ShaderAttribute::SetShaderParameterValue

Sets a shader parameter value.

void SetShaderParameterValue(int32 slot, const Vector4D& param);

slot	The shader parameter slot. This can be between 0 and 7, inclusive.
param	The new shader parameter value.

The SetShaderParameterValue function sets the shader parameter value indexed by the slot parameter to the value specified by the param parameter. This affects all constant processes in both shader graphs contained in the shader attribute. For vector and color constant processes, all four components of the parameter are used. For scalar constant processes, only the x component of the parameter is used.
