I want to get this result but I cant get the anisotropic shader to work.
I have already unwarped the object but the reflections are still not working right. Thanks!

You need to set different values for U- and V-roughness.

Thanks but I would like to get the result on the right side of the picture I rendered in cycles.

Picture:

LuxCore requires a different UV map, you need something like this:

I tried to use every possible UV unwarping I could but the result still looks very different from the reference image or the image I rendered in cycles.

You can see some weird blocky reflection artifacts and the reflections are not centered.

Here is the same scene I rendered in cycles:

Maybe Dade can tell us more?
I actually don't have much experience with anisotropic materials in LuxCore.

UV texture normal map, or physical mesh displacement should work.

Yes I hope he can because I'm working on a project and I'm curently stuck.

The situation in my example file somewhat improves if I use 4 subdivisions instead of 2:

This is a quick test render from my scene where I tried using a bump map for anisotropic material on the control knob. It looks ok but it could look a lot better if I could use the real anisotropic shader.
