public void SetMatrix(string name, Matrix4x4 val);
public void SetMatrix(int nameID, Matrix4x4 val);

Parameters

name The name of the property being set.
nameID The ID of the property as given by Shader.PropertyToID.
val The matrix to set.

Description

Sets the value of a matrix uniform.

The matrix specified as argument can be used only by the shaders defined inside the .raytrace file associated with the RayTracingShader. If the value needs to be visible in all ray tracing shader passes (hit groups in DirectX Raytracing terminology) then Shader.SetGlobalMatrix must be used.
