| kernelIndex | Which kernel to query. A single compute shader asset can have multiple kernel entry points. |
| x | Thread group size in the X dimension. |
| y | Thread group size in the Y dimension. |
| z | Thread group size in the Z dimension. |
Get kernel thread group sizes.
Work group size for each compute shader kernel is specified in the shader code itself
(using "numthreads" HLSL attribute). Use this function to query it.
