[Scene 3D] [FBX] : Mesh normals are invalid (some values are null) and will be recomputed

[olegbeliy65]

Hi, I created a model and when I export it to Substance Painter I get an error [Scene 3D] [FBX] : Mesh normals are invalid (some values are null) and will be recomputed I have created models before and have not encountered this problem.
I have already cleaned the mesh and tried some methods and nothing helps what to do?
Please help me

Hi!
Try to select all vertex and merge their.

I have still to find a direct solution, but I can offer a work around.

Just export the mesh from Painter which now has the new created normals from which you baked. This will prevent any bruising in the engine.
