SetInts(_DispatchSize, intArry[4]), where intArry[4] was filled with values. It is applicable only on ConstantBuffer and cbuffer declarations. The rest are garbage. y)] Share. In summary - mapping structures from C# to HLSL cbuffers is non-trivial, but can certainly be done in entirely managed code. register. November 06, 2012 05:36 PM. To keep things simple and fast, the compiler indexes the cbuffer register in order to access the array and chooses to keep the component access static. 1. The equivalent functionality to a "cbuffer" in GLSL is a uniform interface block, who's data comes from a buffer object. As a possible optimization you could use a NULL depth/stencil target. One of the hand-wavey parts was how to go from the cbuffer layout in HLSL, to proper offsets where to put the final parameter values within a buffer. Index: Optional array size. When compiling a shader or an effect, the shader compiler packs structure members according to HLSL packing rules. cbuffer { float2 position; //offset = 0, size = 8. So, if you were to compile that HLSL to SPIR-V, you could then ask SPIRV-Cross to turn it into GLSL to find out the GLSL equivalent. The only real restriction is you can't have the same resource bound as an. Instead you should be doing: CBUFFER_START (MyColorCBuffer) float4 _MyColor; CBUFFER_END. See HLSL, User-Defined Type. When you declare a float3x1, you are declaring a matrix with 3 columns and one row. I was programming a hull shader for a terrain rendering with lod today. I am in the process of implementing lighting in my DirectX 11 project. profiles; while '. Wait on the GPU to finish. Vertex shader outputs that are used for pixel shader inputs are linearly interpolated to get per-pixel values during rasterization. [PATCH v2 5/9] vkd3d-shader/hlsl: Detect overlaps in cbuffer offsets. s*#*: A register for a sampler. So, for example, your float3s are actually being padded-out to float4 size in your HLSL. I know that each "float" in the array below gets a 16-byte slot all by itself (space equivalent to float4) due to HLSL packing rule: // C++ struct struct ForegroundConstants { DirectX::XMMATRIX transform; float bounceCpp [64]; }; // Vertex shader constant buffer cbuffer ForegroundConstantBuffer : register (b0) { matrix transform; float. However, on Vulkan only the first light is valid. it says "Material property is found in another cbuffer than 'UnityPerMaterial' ( my property name ) " I did all i can to track it. hlsli","path":"Data/SkyeCuillin/BRDF. 19042. hlsl 文件中提供的计算主光源阴影函数默认主光源是平行光（无透视）、提供的计算额外光源阴影函数默认所有额外光源是有透视的，如果需要额外的平行光，可以自己写一个计算函数。. They are typically substantially smaller, and are used as input and output locations for processor instructions. In HLSL syntax you define constant buffers with cbuffer. You can bind up to 128 texture buffers per pipeline stage. More info See in Glossary. Interpolation Modifiers Introduced in Shader Model 4. cbuffer A {namespace N { }} is tricky to support because the namespace N decl inside cbuffer needs to be accessed by things outside the cbuffer. Windows Terminal HLSL modification. Any corrections, verification, or clarification on this topic is much appreciated. HLSL/Direct3D requires cbuffers to be padded to 16 bytes alignment, pmfx allows you to create cbuffers with any size and will pad the rest out for you. It looks like you need to remove the CBUFFER_START block from comments so you will have a constant named _Color to match your Shader property named _Color. 1. The totality of the concept is called a "Uniform Buffer Object". but I have not got really smart from it yet. And of course, this means that structs in HLSL also. Specifying root signatures in HLSL Shader Model 5. Any insight would be appreciated. This time, locate the Shader Type field and set it to the appropriate shader type using the dropdown menu. Buffer. Download ZIP. Assuming You are talking about HLSL constant buffers, in the HLSL documentation we can read: Constant buffers reduce the bandwidth required to update shader constants by allowing shader constants to be grouped together and committed at the same time rather than making individual calls to commit each constant separately. // animation the vertex based on time and the vertex’s object space position3. Once the file is included you should be able to access the cbuffer like a regular variable within your shader. hlsl files as they cover a lot of the same ground (defining generic engine level transform variables and globals, etc. hlsl in front of other paths, or just simply put #include "Common. 3. See register (DirectX HLSL). COMMON { #include "common/shared. unity. Fork 2. However. I am in the process of implementing lighting in my DirectX 11 project. More info See in Glossary compiler that isn’t covered by other types of preprocessor directive. Hey everyone, I'm a little confused about the -not_use_legacy_cbuf_load command line option, and how it ties into cbuffer layout. uv = TRANSFORM_TEX(IN. . It will have the same blank scene as before, but should have produced SkyboxEffect_VS. You can put #pragma directives anywhere in your HLSL code, but it is a. 8. Each set of user constants is treated as a scalar array of 32 -bit values, dynamically. SHADERed. Now just bind the constant buffer to your vertex shader: m_deviceContext->VSSetConstantBuffers ( 0, 1, &cameraCbuffer ); Note that the first parameter maps to the register you used in your shader cbuffer declaration ( b0 in this case). ConstantBuffer or cbuffer blocks can now be mapped to this storage class under HLSL by using [[vk::shader_record_nv]] annotation. shader. exe command-line compiler or use one of the HLSL compile APIs, like the D3DCompileFromFile API. universal以下のhlslファイルを使うことが. So, for example, your float3s are actually being padded-out to float4 size in your HLSL. hlsl, and DepthOnlyPass. So, a float is 32 bits, which is 32 / 8 == 4 bytes. HLSL half type maps to full 32-bit float type; In native 16-bit mode (compiled with -enable-16bit-types): min-precision types map to native 16-bit types; HLSL half type maps to native 16-bit float16_t type; native 16-bit types have storage size of 16-bits (as expected) Doubles and 64-bit ints have a storage size (and alignment) of 64-bits (8 bytes) Historically the extension '. One more thing, matrices in hlsl are column major by default. // C++ struct IndexConstantBuffer { unsigned indexes [32] {}; }; // hlsl cbuffer IndexConstantBuffer : register (b0) { uint indexes [32]; }; D3D11 WARNING: ID3D11DeviceContext::DrawIndexedInstanced: The size of the Constant Buffer at slot 0 of the Pixel Shader unit is too small (128 bytes provided, 512 bytes, at. fx' refers to a HLSL shader intended to be built using the legacy effects fx_4_0, fx_5_0, etc. if y is a vector, it is treated as a column vector. hlsl file. You may want to create a function that encapsulates the functionality of a vertex shader, pixel shader or texture shader. The memory layout of the HLSL and the C++ struct have to be identical, so watch out for the packing rules. core/ShaderLibrary":{"items":[{"name":"API","path":"Packages/com. hlsl) and there is another one which has a vignette effect which dims the corners of the screen (retro2. 7 to 12. cbuffer MyBuffer { float4 Element1 : packoffset(c0); float1 Element2 : packoffset(c1); float1 Element3 : packoffset(c1. Unity might even split out a bunch of errors if you try this (I haven't). CBUFFER_END . {"payload":{"allShortcutsEnabled":false,"fileTree":{"Packages/com. New subject: [PATCH v3 2/4] vkd3d-shader/hlsl: Check for non-static object references on resource stores. fx' refers to a HLSL shader intended to be built using the legacy effects fx_4_0, fx_5_0, etc. cbuffer_end then in the csharp awake/start, i computeShader. cbuffer member initializers will simply trigger warnings and be ignored by the compiler. To get the 3D effect, I use the typical model view projection matrix multiplication in my HLSL shaders. ConstantBuffer or cbuffer blocks can now be mapped to this storage class under HLSL by using [[vk::shader_record_nv]] annotation. The one output in the Header File Name property of VC++ is the second. if x is a vector, y is treated as a row-major matrix. Using the Properties block To assign material properties to a Shader object in ShaderLab, you place a Properties block inside a Shader block. fx /Tvs_5_0 /EVSSkinnedmain. If you wish to add light and shadow, do it in the vertex function. The main difference is that in HLSL, the access method is part of the “texture object”, while in GLSL, they are free functions. Previous. Thanks! Last edited: Jan 20, 2021. This can only be specified at global scope, not inside a structure, and the packing rules will apply for all subsequent declarations. Take reference/Copy-paste from the UnlitShader for the vert inputs and outputs. Meaning that a cbuffer in HLSL =~ a struct in C++ (at the condition that the struct members are correctly aligned to the HLSL cbuffer aligned rules). 9. Glslang . uv,. Instead, for your new apps, we recommend that you use HLSL's new texture objects (Texture2D, Texture3D, and so on) and sampler objects (SamplerState and SamplerComparisonState). In this article. 0 ``` so that the tests that follow do not get run with the vulkan backend on SM4. MSDN's description for tbuffers is the following: A texture buffer is a specialized buffer resource that is accessed like a texture. Historically the extension '. Unity must know they belong to a group and uploads them together when needed. In addition to the built-in intrinsic data types, HLSL supports user-defined or custom types which follow this syntax:The registers in HLSL are made up of sets of four 4-byte sections for a total of 16 bytes per register. Comparison Operators1. Let's say I want to pass some kind of value to a pixel shader in HLSL. COMMON { #include "common/shared. I have a cbuffer that holds the view and projection matrices and would like to multiply those with the vertices as they are passed. cbuffer : register(b1) { float4 a; int2 b; }; Currently, the shader compiler supports the ConstantBuffer template for user-defined structures only. Build and run your project. 1 Answer. – Maico De Blasio. And of course, this means that structs in HLSL also. cbuffer MaterialBuffer : register. I made a custom Unity shader for the Universal Render Pipeline (URP). In HLSL, you’ll sample a texture called Texture with a sampler called Sampler like this: Texture. Use the following syntax to declare a buffer variable. The common shader core provides a full set of IEEE-compliant 32-bit integer and bitwise operations. h","path":"SimpleBezier11/MobiusStrip. there are no syntax errors in . 18f1 and upgraded to 2022. Your closest way is indeed to work with structs (and make sure that you use the struct both in the cbuffer declaration and as function input. その際、CBufferの変更に注意してください。 シェーダーのパスやCBufferなどについては(これは執筆中です)の記事で解説しているので、そちらも参考にしてください。 00 テンプレートConstant buffer or "cbuffers" as known by HLSL is a buffer/struct which is stored in GPU memory and can be accessed within your shader. IDXGISwapChain1::Present1 the frame. You can also provide instance data in the input layout by using D3D11_INPUT_PER_INSTANCE DATA instead of D3D11 INPUT_PER_VERTEX_DATA. HLSL Packing Rules for Constant Variables Article 08/11/2020 3 contributors Feedback In this article More Aggressive Packing Related topics Packing rules dictate how tightly data can be arranged when it is stored. (why. count * statesB. Work on Vulkan back-end and general rending refactoring since early 2018. #3: Set that cbuffer as active for both shaders before rendering. The additional MarshalAs attribute on the array is the key to getting this to work. 3) Put the static keyword in front. Follow edited Feb 7, 2015 at 11:43. Over the past year we've been chipping away at integrating Microsoft's "new" HLSL compiler, called "DXC". This tutorial is made with Unity 2019. hlsl, ShadowCasterPass. It is applicable only on ConstantBuffer and cbuffer declarations. I'm trying to move over an array of constant structs from a structuredBuffer to a Cbuffer in a compute shader. Note that constant buffers for historical reasons are viewed as sets of 4x32-bit values. Share Improve this answerOn the other hand, if I decided to remove the denominator of Cook-Torrance formula. HLSL register assignment. Does this then follow through meaning that: a. 3. Variables are packed into a given four-component vector until the variable will straddle a 4-vector boundary; the next variables will be bounced to the next four-component vector. #2: Make 1 cbuffer object that matches the layout in both shader files. In HLSL, you pass Direct3D state explicitly from the app code to the shader. 0 and lower, or tests that require target profile 6. The rest of this page assumes shaders do not interact with Unity lights like special effects and post-processed effects. In HLSL, you pass Direct3D state explicitly from the app code to the shader. That's why final matrices are transposed in C++ before being set in cbuffers. What I know: I know that a register is 4 floats (16 bytes), and that a variable cannot straddle two registers so padding is added according to HLSL packing rules. It covers the writing of shaders and drawing multiple objects efficiently. Created June 24, 2021 16:30. You would probably use cbuffer MyCB and then use the GetConstantBufferByName method to find it rather than the unnamed cbuffer for reflection. This was a feature of HLSL used for the legacy Effects system. and then including that file into all the shaders im using. cbuffer MyBuffer { float4 Element1 : packoffset(c0); float1 Element2 : packoffset(c1); float1 Element3 : packoffset(c1. Environment Platform ServicePack Version VersionString Win32NT 10. After that if you want to modify the data you can just modify the buffer itself. } In HLSL, we have cbuffers and tbuffers. One of those shaders might garbage data as the two cbuffer definitions conflict. register. There are five different types of buffer objects in HLSL shaders, and each type requires that shader authoring and resource setup be done in slightly different ways. Compilation. hlsl it's declared with UNITY_DEFINE_INSTANCED_PROP(float4, _InstancedColor) within a. If you define all those properties in CBUFFER named // UnityPerMaterial, SRP can cache the material properties between frames and reduce significantly the cost // of each drawcall. ByteAddressBuffers are very annoying. . struct RTHandleProperties { int4 viewportSize; // xy: curr, zw: prev int4 rtSize; // xy:. You'll almost certainly need to split your cbuffer in two - lights per-vertex and lights per-pixel - with the per-vertex buffer containing the bare minimum of data. but I have not got really smart from it yet. The problem seems to have been that I didn't include a depth only pass in the shader. However, building this library should be fairly straightforward: just compile src/*. Star 1. From: Francisco Casas <fcasas(a)codeweavers. cbuffer TImageParams : register(b0) { int2 RawImageSize; // Actual image size in RawImage } struct TDataOutBuffer { uint Lock; // Use for SpinLock double GrayAutoResultMean; double GrayAutoResultSumSqr; }; ByteAddressBuffer RawImage : register(t0); RWStructuredBuffer<TDataOutBuffer> DataOutBuffer : register(u4);. As. Data Types (HLSL) HLSL supports many different intrinsic data types. New subject: [PATCH v3 2/4] vkd3d-shader/hlsl: Check for non-static object references on resource stores. The plan is to keep the legacy features as is. In the hlsl file I defined the constant buffer as follows: cbuffer FilterParameters { float g_aFilterWeight[7]; }; When doing this, the array will never hold the values I inserted in the C++. NumElements - Array size of the input, which depends on the PrimitiveType as shown in the following table. It is applicable only on ConstantBuffer and cbuffer declarations. Code Revisions 1 Stars 1 Forks 2. CBUFFER_START(UnityPerMaterial) float4 _BaseMap_ST; CBUFFER_END To apply the tiling and offset transformation, add the following line in the vertex shader: OUT. The int and uint data types in Direct3D 10 HLSL map to 32-bit. 1. if x is a vector, it is treated as a row vector. 1 Answer Sorted by: 3 The equivalent functionality to a "cbuffer" in GLSL is a uniform interface block, who's data comes from a buffer object. Name. Scene illuminated by a single mixed-mode light, plus a little emission. To support older DirectX 8 era HLSL programs, matrix by itself is a typedef for matrix<float,4,4>. #include では、計算に使う関数などがまとまっているファイルをシェーダーに含めることを宣言しています。. h","contentType":"file. SetData(GraphicDev->GetDeviceContext(), finalTransforms. Here is my function: float3 load_vertex (int i) { int i_location = i * 12; float3 ret = float3 (0. Sample (AlbedoSampler, uv0); Or, even better, you can easily make it an optional feature by having a known invalid index and check it:If the vertexShader and fragmentShader properties form a valid URL with the file or qrc schema, the bytecode or HLSL source code is read from the specified file. For example, with Direct3D and HLSL, the input to the vertex shader must match the data format in the vertex buffer, and the structure of a constant buffer in the app code must match the structure of a constant buffer ( cbuffer ) in shader code. color in C#. But couldn't found the problem. The following compiles the Pixel Shader using Shader Model 5. 咕了2天，一直在研究阴影的投射问题，A大的ZB雕刻课也开了，每天得抽时间雕模型，更新的速度会逐渐慢下来。. In C++, you should be using #pragma pack(4) for your cbuffer structs. com> We need these checks to properly handle tests that require target profiles 3. 0 Steps to reproduce Write a simple HLSL shader that uses Time such as: // The original retro pixel shader Texture2D shaderTextur. ) so you only want to use either UnityCG. Keep in mind that all registers in HLSL are vec4's. HLSL FX Powerful shader specification and interchange format Provides several key benefits: Encapsulation of multiple shader versions Level of detail Functionality Performance Editable parameters and GUI descriptions Multipass shaders Render state and texture state specification FX shaders use HLSL to describe shading algorithmsSorted by: 4. Working With D3D11/OpenGL Shader Reflection. Let's say I want to pass some kind of value to a pixel shader in HLSL. 1 Answer Sorted by: 8 There are more differences between constant and structured buffers. This is a fixed funtion shader, which currently will generate a Builtin shader rather than a URP shader (if you select the shader and look at the inspector for it, you can compile the 'Fixed Function' code, and you will see why it will not work with URP). hlsl语法cg的引入变成了hlsl的引入，即cginclude endcg变成了hlslinclude endhlsl。. To compile a shader: Compile HLSL shader code by calling. HLSL packs data so that it does not cross a 16-byte boundary. Without that, . (why. Single and HLSL for GPGPU with XNA. buffer object: buffer; See D3D11_SUBRESOURCE_DATA and D3D11_BUFFER_DESC and for a general-use buffer definitions. This means that the the array elements must be aligned on float4; for example, float4 data requires no padding, float3 data needs one float padding for each element, float2 data needs two floats, and so on. 这两天研究了屏幕图像相关的内容，有一些心得记录下来。. cbuffer is a legacy feature for HLSL while type alias is a new feature for HLSL2021. 10. cginc or. One of the scalar, vector, and some matrix HLSL types. What's the equivalent function to this? Any help will be appreciated. You can have a look at any Direct3D11 samples from DirectX SDK, you will see that C++ struct are mapped to cbuffer directly. {"payload":{"allShortcutsEnabled":false,"fileTree":{"Packages/com. In our simple OpenGL ES 2. First, it is possible to attach a root signature string to a particular shader via the RootSignature attribute (in the following example, using the MyRS1 entry point): syntax. So, in a constant buffer, you want your values to align to those 16/256 byte boundaries (and will be required to fill up to the next 16/256 bytes). unity. Posts: 39. In short, for the case of arrays, this means they must start on a 16-byte boundary. Configure material properties per object and draw many at random. uv = TRANSFORM_TEX(IN. Support the SRP batcher, GPU instancing, and dynamic batching. Share. x. In HLSL, there is only scalar alignment required for a load-store with no way for HLSL shaders to signal intended alignment. So, you should be able to just do this: RWBuffer<int> indices; then access it like this: indices [int (id. {"payload":{"allShortcutsEnabled":false,"fileTree":{"Engine_Source/Source/Shaders/HLSL/Forward_Rendering":{"items":[{"name":"Forward_Rendering. isSupported return false. For example using a structured buffer: StructuredBuffer<CInstance> instanceBuffer :. Yes In your HLSL code, you must put per-material variables in the same CBUFFER for SRP Batcher compatibility. 0 Microsoft Windows NT 10. For example, most tutorials that I have seen setup the buffer as. This is also why you may need to add padding between subsequent fields when alignments between the host language (C/C++/C#/etc. y); } See also. This is the fifth part of a tutorial series about creating a . In HLSL, you can use the following types of preprocessor directive to provide information to the shader A program that runs on the GPU. These matrices are uploaded to a d3d11 constant buffer. A structured buffer is another kind of DeviceBuffer resource available to shaders. Suppose i have a following HLSL vertex shader fragment with constant buffers: cbuffer matrixBuffer { matrix worldMatrix; matrix viewMatrix; matrix projectionMatrix; }; cbuffer matrixBuffer2 { matrix worldMatrix2; matrix viewMatrix2; matrix projectionMatrix2; };0. // Textureをグレースケール化させるShader // _Ratioが1の場合グレースケール、0の場合は元のTexture表示. Do you have a cbuffer with a capacity of 102400 lights? Could this be problematic if one uses more than one shader, since one needs to rebind the pixel shader every frame and thus also. 如果对该Shader实现原理层面不太了解，建议移步我之前对 《Shader入门精要》 一书的学习笔记博客。. fx' files without any technique/pass statements. In HLSL, we have cbuffers and tbuffers. My current understanding is that the buffer stores a series of bytes which can be accessed in chunks of 4 bytes (and from testing I believe that accessing a non-aligned address rounds the index down to a multiple of 4). hlslに書いてありますが、LUAから渡されていない変数も多いようなのであまり当てになりません。 基本的には、LUAを経由します。1. Type is one of the following: Type. Single . Shader Model. 0 #pragma exclude_renderers vulkan #pragma vertex vert #pragma fragment frag // The rest of your HLSL code goes here. It seems to be the case, but I. Right click on the . More info See in Glossary compiler that isn’t covered by other types of preprocessor directive. In this example this block is empty. When I added the depth pass it works even in the editor window. herohiralal / GlassShader. Draw Calls. To initialize a constant buffer. Rendering involves a call to populate the command list, then the command list can be executed and the next buffer in the swap chain presented: Populate the command list. For example, it doesn’t accept function output. They provide additional information to the shader A program that runs on the GPU. Note Instead of using this function, we recommend that you compile offline by using the Fxc. 1 Answer. // In this case, for sinmplicity LitInput. // The DepthOnly pass is very similar to the ShadowCaster but doesn't include the shadow bias offsets. register(cb1) settings in the HLSL. To help you better understand how to use vectors and matrices in HLSL, you may want to read this background information on how HLSL uses per-component math. ComputeShader programs often need arbitrary data to be read & written into memory buffers. Variables. Create transparent and cutout materials. md","path":"tests/bindings/README. 1. cpp (in C++11 mode!) and src/cbstring/*. More info See in Glossary compiler that isn’t covered by other types of preprocessor directive. {"payload":{"allShortcutsEnabled":false,"fileTree":{"Data/SkyeCuillin":{"items":[{"name":"BRDF.

I also know that if I compile two shaders (say, vertex and pixel shader) in from the same file the register specified are by shader usage so if I use register b0 two times everything. Configure material properties per object and draw many at random. (A sampler defines the lookup behavior for texels in the texture resource. Supported. } In this particular case I use slot 0 for both shaders. The actual layout of the structs on the c# and hlsl sides do not actually matter that much. hlsl" // Contains PerViewConstantBuffer_t } VS { #include "common. color from the shader will still try to address &light + sizeof (float3)+sizeof (float3) as defined in the cbuffer, but you will get incorrect results due to array organization policy of HLSL. In Unity, shader programs are written in a variant of HLSL language (also called Cg but for most practical uses the two are the same). 0f, 0. HLSL in Vulkan has been achieved through integrating a SPIR-V backend into DXC, Microsoft’s open source HLSL compiler. Over the past couple of years HLSL in Vulkan has made amazing strides to hit a critical maturation point and earned the coveted label of production ready. Buffer< Type > Name; Parameters Buffer Required keyword. 5. Vectors are just multiples of the scalar (so if float is 4 bytes, float4 is 4 * 4 == 16 bytes). python3kgae updated this revision to Diff 448407. {"payload":{"allShortcutsEnabled":false,"fileTree":{"SimpleBezier11":{"items":[{"name":"MobiusStrip. The same shader on the same PC device turns to be not supported on GPU. My current understanding is that the buffer stores a series of bytes which can be accessed in chunks of 4 bytes (and from testing I believe that accessing a non-aligned address rounds the index down to a multiple of 4). Sep 8, 2015 Posts: 186. NelsonP. Functions (HLSL reference) Functions encapsulate HLSL statements. x component. My approach of having constant buffer i want to "share" is to have a constant buffer struct in a include file. hlsl. . This is to some degree hidden by the HLSL compiler since it'll bump the cbuffer size up for you silently. lilacsky824. There are two main ways to do this. This article will cover a part of that, the packing rules of HLSL cbuffers. )cbuffer padding. hlsl' refers to individual HLSL shaders. To match the second c# structure using InternalTestStruct, you'd need to do: cbuffer PerFrame : register (b0) { float3 eyePos; int dummy; //Here you need to force the padding InternalType internalStruct; } If you change internaltype to a size larger than one the padding will then become automatic (but it's always nice to keep it explicit). It will now continue in project form. SetConstantBuffer ("states", statesB, 0, statesB. com> We need these checks to properly handle tests that require target profiles 3. exe に渡しているコンパイルオプションを完全に提示してください。. The library is largely based on the GLSL. Feeding the triangles list to the vertex shader (problem!!!) Instead of using structured buffers (which don't let you bind as a vb), I would look into using raw buffers. The other group. {"payload":{"allShortcutsEnabled":false,"fileTree":{"Packages/com. In HLSL, there is only scalar alignment required for a load-store with no way for HLSL shaders to signal intended alignment. Using SurfaceFormat. This is my buffer: statesB = new ComputeBuffer (total, size, ComputeBufferType.
