| name | The name of the property being set. |
| nameID | The ID of the property as given by Shader.PropertyToID. |
| val | The vector to set. |
Sets the value for a vector uniform.
Only shaders defined in the .raytrace file can access the vector you designate as the argument for this method. To make this vector accessible to all ray tracing shader types (closest hit, any hit, miss, etc.), call the Shader.SetGlobalVector method instead.
