Better tools not mean better mod. Because the mod itself too complicated, like Sasuke from Naruto game. I need to separate three body parts of Sasuke, fixing the UVW, and rig the model. And some polygons still overlapped after some trying.

The one that i forgot before was GTA 4 character mods actually support several varians models and textures in one model (wdd - wtd). I mean for Sasuke, it's possible the model have various eyes textures (like Sharingan), various clothes in single file etc. Edit : i add some textures varians for this mod.
