Distorted UV's only on bevel on import

I’ve been hit with this issue again- it seems really inconsistent- sometimes some beveled edges look fine, but the majority of the time, I get at least 50% of the bevels having this big striped distortion, like an obvious seam in my mesh. I’ve tried all kinds of different UV mapping and it always looks fine in Maya with the checker material applied, but in UE4 the stripes appear on import. Any tips or fixes for this??
