Hi, i need a custom parameter for a material for the OctaneRenderer which must have an unused type. The material should also render as a simple lambert/phong in MentalRay. For an other material, it is working, only the material with the custom parameter makes trouble.
I have build a custom parameter shader type with: CStringArray type; Application().RegisterShaderCustomParameterType( L"OctaneMedium", L"", L"" , 255, 255, 255, type, type); and use it in a shader parameter definition container. In the render tree, all ports are shown how they shall. The new parameter is only used internal and shouldn´t affect the MentalRay output. Now the problem i have. MentalRay don´t known the new parameter and gives me back an error message, which should be logical. Is there a way to make the parameter known or invisible, so that the error message disappears and i can render the material with MentalRay? Stephan
