A new tip tutorial from Max Cookie to start talking about Production Shaders in 3ds max 2010 and 2011. We’ll take a look at the Lens Shader called Render Subset of Scene/Masking, useful to create masks using an object selection or choosing a material. It can be used to render different shader setup or when we have to fix some stuffs just on a part of our scene, to speed up the pipeline. For example it can
be used to render different colored version of a product that can be composited later over final image.

We’ll see how to add it in our scene, we’ll talk about all its parameters, and we’ll see how to render a complete scene, and then comp over it just a part rendered using this shader inside Autodesk Composite, (aka Toxik).
