Bump!
This really needs an answer. I haven't been able to find any programs which convert .bwm files, although I've seen community mods which make use of original .bwm model files (that neans someone, somewhere knows how).
I'm going over the scripting tutorials and slowly figuring it out, but as a 3d modeller theres some things I'm dying to try to put into the game (heavy infantry, new walls, siege towers, etc
).
So, some charity for the untalented would be nice.
