Shaders rollout The controls on this rollout let you assign a map or shader to the Multiplier parameter. Click the button for a component to display the Material/Map Browser on page 5290 and assign the map or shader. Use the toggle at the left to turn the effect of the map off or on. The button to the right of the main shader button is for shaders that can return multiple parameters. If a shader that returns multiple parameters is assigned to the component, the button's tooltip shows the parameter name. Clicking the button displays a Connect Parameter To Shader dialog on page 5981, which lets you change which parameter is being used. IMPORTANT UV Coordinate on page 6013 and XYZ Coordinate on page 6017 are the only shaders with multiple return values provided with 3ds Max. You might encounter multiple return values in shaders provided with other shader libraries or custom shader code. DGS Material Shader (mental ray) Material Editor > mental ray Connection rollout > Unlock the Surface or Photon component. > Click the shader button for the Surface or Photon component. > Material/Map Browser > DGS Material (3dsmax) Material Editor > mental ray material > Click the button for the Surface or Photon component. > Material/Map Browser > DGS Material (3dsmax) Note: Shaders appear in the Browser only if the mental ray renderer is the currently active renderer. DGS stands for Diffuse, Glossy, Specular. This shader is a mental ray phenomenon (a scripted shader tree) that provides a physically accurate simulation of a surface. With the mental ray Connection rollout of a basic 3ds Max material, or a mental ray material, you can assign the DGS Material shader to either the Surface or Photon component. Despite the similarity in name, this shader is distinct from the DGS material on page 5615. Both, in turn, provide a custom 3ds Max interface to the "DGS Material Photon" shader that is part of the mental images physics library. mental ray Shaders | 5987
