Java games rock!

Hello,

For a 2D game, I have a tile map, each tile representing a portion of a bas-relief pattern by use of a grey scale, and/or alpha channel.  What I want to do is combine this with a texture pattern, such as marble, to get a bas-relief marble (or whatever) effect.  This also includes transparent sections where the background shows through.

Thing is, I can't really suss out how to do it.  What I need is something like combining the colours from the texture pattern with the alpha channel from the tile set.

I suppose I could make all these tiles in a paint package but then I'd have to do a set for every level, rather than just combining a tile set & texture on the fly.  I also like having the texture repeat at a larger scale than the tile size (48*48 ).

Any ideas?  Cheers.

You could use ARB_texture_env_dot3 which gives you proper bump mapping instead of crappy old basrelief. Yum!
