I had this issue before with one of the versions of 4.7, but it was resolved in a latter release. Now this issue has surfaced again and I still can’t find a solution. Hopefully someone here has come across it as well and can inform me how to fix it. I’m checking my packs for compatibility for 4.10, and I noticed this. The normals are completely messed up. I’ve tried reimporting, others have suggested in the past to uncheck MikkT normals and that didn’t work either. Any insight into this would be much appreciated.
