Is Specular + Dot3 + colored lights possible?

Hello, I am making a model previewer program in Blitz3d for someone... but he wants the following features...

specular mapping
normal maps
multiple light setups (meaning colored lights)

I have seen normal maps done in Blitz3d, but I don't believe I have ever seen normal maps being used with colored lights. And I have never seen specular maps done in Blitz3d either.

I have tried searching the forum but finding a definite answer to these questions is difficult.

both have been done, were a few demos a long while back, loki and i both did specular stuff combined with normal maps, a search should pickup alot of code etc

Could you please give some info about where we could find it? It seems very interesting!

I did a search and found what you were talking about. Thankyou.
