I imported an fbx in my scene and for some reason parts of the mesh look distorted 
Once I apply textures they look blurry and distorted. It doesnt happen in the whole mesh though, only small parts. At first I thought it was a problem with uvs and textures but in painter they look good and are working as expected. Help pleaseee!
The UVs aren’t good.
A quick way to fix it would be to just do a box projection, either in Blender or UE.
But, it the material layout is complex, you need to unwrap by hand.
