Im tackling this EXACT issue right now but unfortantely Im working on the max side of things... I have been trying to figure out ways to have it import my mesh without horrible seam screw ups etc and not pre calculating my tangents (Seriously unity wtf man) I dont suppose you can toss up examples of what you did so I can…
Big thanks for creating this wonderful little plugin!!! I made a test example to prove it works. The example is a simple window baked on a very low poly mesh with very soft normals. I made it into two smoothing groups to not stress the normals too much. But I am very happy about the result. Cheers! /Jenz
