Summary	0000315: Proper support for shader stages
Description	Some shaders with more complicated diffuse stages are not recognised properly, like this: { blend diffusemap map textures/darkmod/stone/natural/dark_rough scale 1,4 } The scale keyword is not recognised for example. I guess these scale operations can be encapsulated into an "internal" MapExpression that does the scaling before delivering the actual image. This is just an example, there are more unrecognised keywords, although not all of them make sense for the editor (like indices into time tables, vertex programs and such).
Tags	No tags attached.
