the old quake formats are very outdated. md2 packs vertex coordinates into
bytes for example which leads to very imprecise models.

i have looked around on the irrlicht forum a bit and the irrlicht mesh
format still doesn't seem to support animation yet.

most people seem to use the blitz3d format, the milkshape format or the .x
format for animated models with irrlicht.

i think the blitz3d format would be best at the moment since it seems to
have a nice blender exporter. i don't know of a milkshape exporter. the .x
exporter has problems and the .x format is a bit crappy anyway in my
opinion.

for static models like the racing tracks i would use the irrlicht mesh
format.
