LuxCoreRender Forums

Here's a quick three day render I've just completed using Blender, Substance Painter, and of course Luxcorerender. Recommendations are welcome.

The scene is over 300 mb; I'll try recreating the carpet and see if that fixes it.

I have been having a problem while trying to add a carpet to a scene where, when I select "UV Texture Map" for the hair color export mode, the hair does not show in the viewport or final render. I remember having this issue in classic luxrender, however the old forums that are linked from ...

Do you get the same error ?

Yes, I do. You were correct however that disabling OpenCL imagepipeline fixes the error.

Do you have also any other GPU aside from the GTX 1080 ? Like a Intel HD4000 on a laptop (i.e. a GPU known to be unable to run some complex OpenCL kernel). I can confirm that it does not work with Nvidia OpenCL, OpenCL on my Xeons, or OpenCL on my Vega FE card (AMD drives). But are you using the v2...

As workaround, you could disable the OpenCL image pipeline and use the CPU version but I don't know if this option is exposed in Blender It was implemented after the v2.1alpha3 release. But if I understand rrubberr correctly, he compiled from the latest sources, so he should have the option. It was...

Since upgrading to 2.1 Alpha3 I have not been able to successfully run a render. I have been getting the error ClBuildProgram when rendering on CPU, GPU, or both. I also get this error if I compile directly after freshly cloning the repositories.

Thank you for the quick fix.

Can you show your material node setup? Are you using the opacity socket or still the old "mix with null"? The opacity socket is a lot faster. If I remember correctly, it should also not be dependent on the path depth, however in a quick test I can reproduce a darkening effect that appears...
