Here is a preliminary draft document on how to convert NWN creatures to NWN2 using Blender and nwn2mdk (instead of GMax):
I’m still testing the procedure, so it may need to be tweaked a little bit. Anyway, I’m posting it in the hope that one of you would be willing to test it out and independently confirm the steps work. Thanks in advance!
Ed.: Updated to draft version 1.2.
