LuxCoreRender Forums

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

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.

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

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,

Dade,
Thanks for your help. I re-packed the file so it should include the normal map. Could it be a problem with my gpu? With cpu rendering, it's less noticeable. I will try with different gpu at home tonight.

Sorry, I decreased the Normalmap Height before saved the file.
If you increase the height, here is a result I get.

Hi Dez!, thanks for your suggestions, but they don't seem to help with my scene. Besides, every time I change the "epsilon settings", Luxcore re compiles the kernel, another wait for 5 ~ 10 minutes.

Thank you both for looking into the issue. I checked the duplicates and there is none. Yes, Luximage, If I lower the normal map strength, the black spots disappear but so as bump effects. I wonder why it renders differently from version to version (in my case 2.5 and 2.6 alpha0).

Hi there,

I've been having a problem with some places rendered as black. If I change the angle of the camera, they disappear.
I'm using Blender 2.93.5 with Luxcore 2.6 alpha0. If I render with Luxcore 2.5 on Blender 2.92, these spots are less noticeable and they look like dark stains. Link to ...

That'd be really helpful!
