Hi! I am having this issue too and triangulation did not fix it. I also can't seem to find where to turn on "High precision UVs." Would you mind sharing how you did that?
@Mink Thank you for the feedback. I spent a long time trying to figure out this issue. I eventually turned on High precision UVs inside of Unreal Engine 5 and this fixed the issue instantly,
Are your triangles exactly the same? If you didn't export your model with baked triangles before texturing, you WILL have triangulation errors. Remember that quads are extremely prone to creating non Euclidian surfaces (they almost always do) and need to be resolved before attempting to render in any realtime application.…
