@tzur_H: I export from modo and modo exports normal data. You can export tangents and binormals in 901 but if you are going for a synched workflow you don't need them afaik. Also binormal shader doesn't need to be on for Unity according to Farfarer. It definitely needs to be on for Unreal though. I doubt that morph cage…
@Tzur_H: can you attach your tangent space normal map? Such artifacts (triangles) are ok for this mesh, because it's very messy. But normal map looks like it should i.e. the same as in Unreal, so I guess it works just not in my Unity. I wonder what settings are wrong.
So after Unity 5.3 release I have tried to do it once again - bake a mesh with one smoothing group and import it into the engine with synched normals. The normal map was converted in Xnormal from object space map baked in modo. It worked totally fine on test cubes but as soon as I import a more complex mesh it breaks: It…
