Weird squares on imports

Hey all,

So i’ve had no real problems with Datasmith until recently. When importing my scenes they look like they come in just fine, but after baking my lights i get this weird square look across the mesh. I think what it is doing is assigning the lights to bake on the wrong channel, and when applying them it puts it in the wrong UV locations giving this weird look.

Theirs no common denominator i can trace between what causes this to happen. Its random meshes across anything i import recently. This is all from 3ds max.

If anyone has had similar and knows how to fix it, that would be amazing :smiley:
