The way we have been doing the texturing is at the RSD stage 
of the conversion; the .rsd file itself specifies the
number of textures for the 3d object, and which TIM files
they are. When rsdtool converts this to TMD, the resultant
TMD effectively expects to use various areas of VRAM as 
textures.

E.g. if the rsd model is textured with 1 texture, stone.tim
(eg 16bit, 64 by 64, positioned at 640, 0 in VRAM)
then the tmd created will use that area of VRAM as the texture
for the model. (Clearly the correct TIM must be loaded
into memory then VRAM).


Hope this enables you to do the business
