anisotropic metal UV problem
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.
Re: anisotropic metal UV problem
LuxCore requires a different UV map, you need something like this:

Re: anisotropic metal UV problem
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.

Re: anisotropic metal UV problem
UV texture normal map, or physical mesh displacement should work.

The situation in my example file somewhat improves if I use 4 subdivisions instead of 2:
Re: anisotropic metal UV problem
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.
