Textures Distorted in UE4

I do not know how to fix this issue. The texture looks great in Painter, but gets distorted in UE4 (also happens in Maya). It is the same mesh and same texture maps. Anybody know what is going on?

I am not a substance person (yet) but I am wondering if you tried to specify “use full precision UVs” on the mesh? This should be a setting on the static mesh viewer. It is odd you say it repros in maya too though. I wonder, could substance be doing something other than linear interpolation of the UVs across polygons? I would hope not since it should match what most renderers use.

Did you triangulate the mesh before importing it to Substance Painter? UE4, Maya, and Substance might be triangulating the mesh in different ways.

Zac,

You appear to be spot on. Apparently Substance Painter triangulates differently than Maya and UE4. Triangulating in Maya prior to export corrects the issue. Thanks!
