ArgumentException: Buffer 'MyBuffer' has been declared as a structured buffer in the shader, but the C# script is binding a different type (ComputeBuffer or GraphicsBuffer)

根因分析

HLSL着色器中声明的缓冲区类型（例如StructuredBuffer）与C#中创建的缓冲区类型（例如ComputeBuffer步幅错误或GraphicsBuffer目标错误）不匹配。

English

Mismatch between the buffer type declared in the HLSL shader (e.g., StructuredBuffer) and the buffer type created in C# (e.g., ComputeBuffer with wrong stride or GraphicsBuffer with wrong target).

解决方案

  1. Ensure the C# ComputeBuffer stride equals the size of the struct used in the shader. For a float3 buffer, stride = 12 bytes. Example: ComputeBuffer buffer = new ComputeBuffer(count, sizeof(float) * 3); shader.SetBuffer(kernel, "MyBuffer", buffer);
  2. If using GraphicsBuffer, set the correct target (e.g., GraphicsBuffer.Target.Structured). Example: GraphicsBuffer gfxBuffer = new GraphicsBuffer(GraphicsBuffer.Target.Structured, count, stride);

无效尝试

常见但无效的做法:

  1. 60% 失败

    Increasing the buffer size does not fix type mismatch; the issue is stride or target, not capacity.

  2. 30% 失败

    Switching to a different shader variant does not change the buffer declaration mismatch.
