Ok, I don't know if anyone already suggested this, so please excuse me if it has already been discussed... But, considering we have a lot of new texturing modes (glow, spec, env), what would be the likelyhood of adding Texture Blending to the mix? This would basically work by having, say, three or four textures for a mesh, where one of the textures specifies the intensity of the others for blending. This is basically the best way to do terrain rendering, but it would also be really good to allow a more seamless integration of tiled maps. The same technique could be used for Detail Maps, something I know Bobboau was already experimenting with...
The only real difficuly here would be to add another mapping channel to the mesh, as I don't know how that could be integrated to the POF data structure, or to the converters.
Comments? And you guys who actually know the code, how hard would this be? And I guess there's one specifically for Kazan too: how hard would it be to add the new mapping channel to the converter? I don't know how Truespace works with these things.
