, 3DS Max, Blender (with plugin here
), anything that supports smd with 4 bone assignments
There is a tutorial and discussion about using 3DS Max written by Jasana_BugBreeder here
. (Read for info, scroll down for a downloadable tutorial). I found some of Jasana's mesh editing techniques interesting - she builds and replaces part of the mesh, instead of modifying it - one thing to say is the tutorial is thorough. Note she has important info about the Max settings in it!
There's a tutorial by Bobcatben here
XSI Modtool (somewhat outdated):
There is a tutorial with basic info about how to use XSI Mod Tool here
. It was originally written for Meshtool's SMD export, so ignore the MESHTOOL instructions, and go to the Mod Tool information. It will be updated for this new plugin soon as I find enough round tuits.
