What's wrong with my UV's?

I’m having a problem with the UV’s after importing a static mesh from 3DS Max

I have included an Image for more detail.

Don’t really know where it is going wrong, any help would be appreciated, thanks.

Hello!

Looks like that when your model comes in engine it has embroidered UV shells and rotated at an angle of -90.
As a user, Maya and Softimage I see this problem for the first time.

Try to triangulate the model manually and remove the checkbox with Triangulate.
Unfortunately, not having the original model hard to determine the cause of this artifact.

Hopefully this will help you.

For whatever reason, this seemed to fix it, though I’ve no idea why when every other model I’ve exported before and after have all worked without any problems.

If anyone else should run into this with 3DS Max (I was using 2015):

  • Convert Mesh to an Editable Poly

  • Select all vertices

  • Choose “Connect” (Very dirty way of triangulating, may not work in all cases)

  • Export with Triangulation unchecked

  • Reimport into UE4

Thanks Dredfort!
