First about the terminology: ray tracing vs path tracing, physically-based vs non-physical, spectral vs nonspectral, etc. "Ray tracing" is really the top-level term to describe the general method, i.e. following the path of a ray of light. Other terms decribe how that is done, for example:...

Made some more progress today but still not building... Yesterday's error was due to a missing glfw installation Afterwards, I also got a build error with spdlog, which was fixed by using the latest spdlog headers from Github (1.8.0 -> 1.9.2) Now I'm stuck with OpenImageIO resulting in errors, looks...

ok I managed to override the replacement by utils/prepare and seems to have worked for compiling openexr. After that, I needed to install also cmake and patchelf (maybe you want to add this to the LinuxCompile Readme? there is a list of requirements there that I did check before) Afterwards it got q...

Hmm, just to be clear, do you mean in the OpenExr source files? the Error comes from an "ImfTiledMisc.cpp". In any case, I have tried to do that, but it just keeps replacing the file in question with the original... - I edited the file in LinuxCompile/distfiles/openexr-2.4.1.tar.gz - I edi...

Hi, after some absence from here I'm using some holidays to refresh my setups, and also trying to get set up again with Linux - Manjaro right now to be precise. I was using only Windows for the last few years, compiling LuxCore only on Windows also as a result of that. After solving an initial missi...

Oh, I didn't notice there was a link

. Few values are here: https://en.wikipedia.org/wiki/Cauchy%27s_equation Since the examples given there are limited to (optical) glasses, we also have a small list at the bottom of the following LuxCore-Wiki article: https://www.wiki.luxcorerender.org/Glass_Material_IOR_and_Dispersion For artistic ...

To me it looks like there are significant differences in material setup that can be addressed. First example is the table in the front. In the cycles render, it looks smooth and like a typical table furnish. In Luxcore, it looks like bump mapping is very excessive, and it looks more like outdoor tea...

I would also rate is as an improvement in most areas. On the plate, it looks like sometimes there can be inverse behavior between some regions. Since the undenoised result is always available, I guess it should be possible to recalculate after rendering is finished. Thats probably on the BlendLuxCor...

I also can't see any specific difference from this image.

Could it be that it is the result of OptiX denoiser, which is active in your scene?
Have you tried comparing to a preview-render with much longer than 10s render time?
