A hundred of congrats!
There are *tons* of free and comercial lightmappers exporting as b3d!
It packs the whole level thing!
People, grab this now
Also animated meshes!!!!!
(a question...while b3d format I think supports spline interpolation, like x, the dx7 old blitz3d engine did only supported linear, for the dx limits I think...are you supporting to grab the spline interpolation, the curves, from the 3d package? there are great exporters for character animation in b3d format in Character Fx, Max, Ultimate Unwrap, etc...)
Some of the experts in code here, please play with it, so to help the man in possible issues, etc...do so now that he's attending the thread
