It seems, like UE has some bugs with importing skeletal meshes from FBX. I have got a lot of models in FBX files, that UE imported with that bug, it’s not the only model’s bug.
Hello. @Steve_T, I know about this way, but there is a problem - 3DS Max can’t handle meshes, that have > 100 morphs - his Morpher supports max 100 morphs. Therefore, I need to import my meshes (with a lot of morphs) directly to the UE.
