+100 to these suggestions.

The Disney plausible model is a delight to work with - much better than the spec/gloss model (in which you can make implausible materials quite easily if you don't know what you're doing).

The Merl database is a fantastic array of materials. They provide good solid measured jumping off points for any photo-real material.

Otoy: Like the documentation, but there's haven't been able to deduce which models are used in the underlying code; please can you elaborate?
