See http://people.scs.fsu.edu/~burkardt/data/mtl/mtl.html and http://local.wasp.uwa.edu.au/~pbourke/dataformats/mtl/ Basically VSL is out of the scope, V3 materials are pretty close to optimal. Some subset of VSL might be doable though, as in textures/constants mapped to color, illumination, specular sharpness/brightness, transparency, bump and optical thickness. Reflection maps are supported as well, but there's no set way to do them in RS. MTL does have some support for procedural textures as well, but I doubt if it'd be of any use to implement them.
