Strange dark triangles

Hi guys! I have a problem with some shadows or UV bug. I can’t understand why this problem happens in my project. The UV map seems to be alright, I checked it in Maya and there is no problem with the mesh. Any suggestion how to fix this? It is extremely annoying. Thanks!! It appears even if I bake the light-map. alt text

Set Normal Generation Method from Mikk to Built in in static mesh editor > Details Panel > Import Settings then reimport and see if it helps.

Also, depending on how far your UV chunks are from the 0,1 space in your UV Map. The further out they are you will need to either fix this in your modeling program or you can try enabling Full Precision UVs in the Static Mesh Editor > Build Settings > Enabled Full Precision UVs > Apply.

You can read a little bit more about it here in this post that I had the other day: UV Precision Bug When Importing OBJ Models - Rendering - Epic Developer Community Forums

Thanks guys, you’re right, the distance was the problem. It was too far from the margin.
