But a psor-cube file is not included in the build, where do I find it?
Right, you can just download a copy of LuxCore source repository from https://github.com/LuxCoreRender/LuxCore (clone or download button). The scene directory includes the psor's cube scene too.

Re: Glass roughness problem

I think the material you should use is "mattetranslucent": https://wiki.luxcorerender.org/LuxCoreRender_Materials_Matte_Translucent https://wiki.luxcorerender.org/images/1/1b/Luxcore_materials_matte_translucent.jpg Roughglass is more intended for opaque glasses like the one used in bathrooms, etc.: ...

Re: PhotonGI cache

So the new PhotonGI cache is not a separate engine but works with all engines? It works only with PATHCPU at the moment (it will work with TILEPATHCPU in the future) and it is intended only for path tracing: it doesn't make very much sense with BiDir because BiDir already traces paths from the ligh...

Re: PhotonGI cache

All other engines work, but not as expected: PathCPU + metro shows no caustics. If you are talking about the psor-cube.cfg, it is configured to use a very strong clamping because caustics are handled anyway by the cache. If you want to render without the cache, you can just remove "path.clamping.va...

Re: PhotonGI cache

There is also a Lightcpu engine (working) I don't remember: Is there a description somewhere? It is another test engine (it is there since the beginning). It is basically a forward renderer: it traces paths from light instead of camera, it is vaguely usable only with Metropolis sampler (and it is v...

Re: PhotonGI cache

The engines tab shows the new Lightcachecpu engine but when I click it the application shuts down immediately including the terminal window so that I have no information about what went wrong. LIGHTCACHECPU is a left over from past development, it was a test render engine and it has been removed (I...

Re: resume render not working

I should have fixed the problem, you can use the LuxCoreUI included in automatic builds (viewtopic.php?f=9&t=736) and it should work fine. The build should be ready in a couple of hours.

Re: PhotonGI cache

Yup, may be reducing the number of concurrent compilations can solve the problem or is it a 32bit vs 64bit compiler problem :?: I have eliminated concurrent project builds for the OpenCL version and apparently this solves the problem. You should find again Windows OpenCL build among the daily binar...

Re: Glass roughness problem

When I try to increase the glass roughness value the edges of the object get very dark. Are also using a volume or not ? It may be worth trying to use glass+homogeneous volume with a lot of scattering, it may be a more accurate simulation of that kind of material. Also, that kind of darkness,may be...

Re: PhotonGI cache

1) Cache entries are currently created only on "matte" material (note: "matte", not "roughmatte"); At first reading I missed this.. So if all my materials are glossy or metals, there will be no caching at this moment? It will bounce over that materials with normal path tracing until it will not hit...
