Description

Adds a command to set a matrix array parameter on a RayTracingShader.

The matrix array specified as argument can be used only by the shaders defined inside the .raytrace file associated with the RayTracingShader. If the matrix array needs to be visible in all ray tracing shader types (closesthit, anyhit, miss, etc.) then CommandBuffer.SetGlobalMatrixArray or Shader.SetGlobalMatrixArray must be used.
