Hello smart people! Gonna make this quick so you can understand. 1. So I have made Mecanim character in Unity (all works perfect). 2. I want to edit/update my character model through 3ds max and then export it from 3ds max back into unity3d again (You know so that i can replace my old character with the new one i made/upgraded in 3ds max ) 3. So i have edited my character model and have exported (replaced) back in unity3d. 4. So now mecanim character should have new mesh and everything i had edited in 3ds max........ But the mesh and structure of my character has completely changed,its F messed up (deformed sizes,mesh looks different and when placing character in scene it somehow dissapears,basically its all F UP!) So i want to know,is there another way to edit MECANIM character mesh (maybe detach some parts from mesh,if needed) in Modelling studio (3ds max..) and then Successfully import model back in UNITY3D engine without any PROBLEMS. You smart people are my only hope. Please if you can,help me out,i will appreciate any help. Thanks!
