Making a custom Smash Bros model?

[Random Talking Bush]

1. Models are made of multiple objects -- only one texture per polygon group allowed.
2. The SMDs should work in Blender. Either way, you'd model a character over another's existing bone structure. And yes, 3DS Max is recommended since its DAEs were what BrawlBox was designed around, but it should be possible to make models in other modelling programs.
