You might need to add some bias to it(within the material editor), just like when dealing with DFAO meshing. In fact, now that I look at it, if it’s using the DF meshes, set your visualization mode to show the mesh distance fields. Look for any artifacts on the meshes BEFORE trying to add any sort of bias in on the material. If you see some, open up the static mesh editor=>details panel=>lod0=>build settings=>distance field resolution scale=>if it’s at 1, try 1.1=>click apply changes=>go back into the level viewport=>check the mesh distance field for artifacts. If it still has any artifacts, keep on slowly raising the resolution scale in small increments until it goes away. You want to keep that resolution scale as low as possibly. If the mesh is all good, then yeah, you’d have to do some biasing work in the material.
ALSO: It’s very important to remember that mesh distance fields do NOT like non-uniformly scaled models. Even if you simply take a cube mesh and flatten it out into a panel, it will hate you and give you all sorts of artifact/banding issues. So if you’re going to scale anything, try to only do it uniformly.
