Root Cause

A CommandBuffer.SetComputeBufferParam call was made with a null or empty string as the shader property name.

Workarounds

  1. 97% success Ensure the property name passed to SetComputeBufferParam matches the name in the compute shader's [numthreads] or buffer declaration. 
    Ensure the property name passed to SetComputeBufferParam matches the name in the compute shader's [numthreads] or buffer declaration.
  2. 99% success Add a null check before calling SetComputeBufferParam to avoid passing empty strings. 
    Add a null check before calling SetComputeBufferParam to avoid passing empty strings.

中文步骤

  1. Ensure the property name passed to SetComputeBufferParam matches the name in the compute shader's [numthreads] or buffer declaration.
  2. Add a null check before calling SetComputeBufferParam to avoid passing empty strings.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    The shader property name must be consistent between C# and the shader code; arbitrary names cause shader binding failures.

  2. 60% fail

    This workaround removes the functionality instead of fixing the root cause.
