Unreal 4 problems importing a mesh?

Evil_Fischi

Hi everyone,
I have stumbled over a problem. Somehow Unreal does not import my meshes the right way. Here It somehow destroys my uvs. The first pic is from Unreal, the second from Max. I have exported the mesh as an FBX.
Does anyone have an solution? Am I missing something? Also I have tried it with checking the auto generate Lightmap uv.

When I export the mesh as an obj, everything is fine, but when I export it as fbx I get those artifacts....

Have you tried nuking your model? As in applying a Normal Modifier to the piece, collapse it then flip the normals in polygon mode so the normals are facing the right way again... then apply a reset XForms and collapse it again as well, then re-export it into UE4? I tend to do this stuff whenever my meshes start acting all weird (Consider it like deleting the history in Maya). I also tend to do this for .FBX models since they carry much more data/settings about the mesh within it, so any scaling/odd rotations etc can be picked up in UE4. .OBJ exports tend to completely nuke the file back to a point where it can be considered a brand new mesh which is probably why .OBJ is working for you and .FBX isn't.

hope that fixes it!

What .fbx version plug are you exporting with? Try rolling  back  to 2014/15 if using newer.

I used to have this problem it's something to do with the FBX exporter try using a different one for now if you put an edit mesh modifier on your object then export it with that on it will be fine

Thank you all!
I have tested out @Adelphia s workaround and it helped. Does anybody know why this happens?
