Hello, I have a problem with the metal in luxcore.
How can I get rid of these dark edges?
I had the same problem in Cycles, but when I switched to multiscatter ggx in principled bsdf, the problem just gone.
I don't see the multiscatter ggx option in luxcore.

Yes, maybe this is problem with normals. But i don't understand why multiscatter ggx solves this problem.

The problem is in how your NURBS are exported to Lux. This is a part of the mesh exported:Rivental wrote: ↑Wed Sep 01, 2021 7:25 pm Yes, maybe this is problem with normals. But i don't understand why multiscatter ggx solves this problem.

As you can see, there are a lot of problems:
- very low triangles count;
- faceted;
- normals flipped (they point inside the object).
My suggestion is to transform the NURBS in triangle mesh inside Blender, so you have full control of what is going on and than render (i.e. export the scene) with LuxCore.
