Do you have an AMD GPU ? They are known to have problems with normal maps.

It looks like the link on the first post isn't valid anymore, I think you have to post a new link.

Here is a new link.

I use Nvidia GTX1080Ti. I have a different Nvidia gpu at home so I will try with it to see if that gives me a different result.

Thanks,

I'm getting this out of the box:


I tested on a RTX 2070 Super and a GTX 980. Are you getting a different result ?

I tried with my home computer (GTX Titan Black) and still got black artifacts...What could it be???

I'm using Linux, I will try if there is something different with Windows. Do you get the same artifacts even if you render with only CPU ?

With CPU, I don't get the artifacts, neither with Luxcore 2.5, only with Luxcore 2.6. Here are the results:
From top, CPU with Luxcore 2.6 alpha - GPU with Luxcore 2.5 - bottom GPU with Luxcore 2.6 alpha.

It may be a driver version related problem. On Linux I have:

I updated the driver from 471.41 to 472.47, but the result was the same.
Thanks for your suggestion though.
