The code (https://github.com/LuxCoreRender/LuxCor ... l.cpp#L213) uses boost::filesystem::temp_directory_path(): it is unclear what it is used on MacOS but it may be /tmp.

It should be in BlendLuxCore addon preferences

Ah thank you ! Silly me that is the only area I did not check!
I wasn't aware of that you can set prefs there.

I know only because I had exactly the same problem However it makes sense once you know addon preferences exist.

Maybe this is some specially configured macOS that wipes itself after restarts? Or maybe just the kernel cache is created in a directory that is wiped? /tmp ? Some unix system usually delete everything /tmp after a boot ? Does MacOS delete everything after a reboot ? Other possible problem may some...

But I tested that on Linux, and it still shows the problem.
Is the orange juice scene working fine on your end?

Yes, it does.

The orange juice scene is now broken (it uses white shadow color for the glass). It looks like you haven't updated your sources, like I wrote, I fixed that problem too. I only tested the latest build from github (on Windows), which shows this problem. edit: I can also reproduce the problem in the o...

Optix/RTX support should be now complete. optix/denoiser next? would be nice for fast feedback in previews Yes but after some work to use Embree on CPU when using Optix on GPU: v2.4 has to use our BVH code when using our BVH on GPU. I want to improve the situation allowing the use of different type...

BTW, Optix builds the BVH on GPU while before it was built on CPU. Since we started to use Embree to build the BVH also for GPUs, BVH pre-processing time has never been a problem however this may lead to some performance difference if you have a very fast CPU with a very slow GPU (i.e. slower pre-pr...

Optix/RTX support should be now complete.

I'm trying with my test scene..but I can't understand why you said that it become black...I've tested both with glossy and specular material and I can't see the black shape of the area light. Where am I wrong?
