I imagine supporting some material proxies might be tough, or at least to support them in the exact same way as the engine.

If I had to choose I would use the source as reference and try to implement my own solution in CG or something like that. For the most part, the shaders are pretty simple and you'll get the same of near enough the same results with your own. A lot of the techniques on how stuff comes together is mentioned in a lot of SIGGRAPH papers so you should be able to emulate it well enough. I think isolating yourself from Source itself will solve any future compatibility problems as well. VTFLib already has code to create/parse VMTs so that wouldn't be an issue and of course it reads the VTF files. So you'ld just need to write your shaders really. - Jed 2009/7/13 Brent Lewis <[email protected]>: > > For some reason clicking reply in hotmail caused this email to go straight > to jed. *shrugs* Second try: > > OK.
