Thank you for the report.
Are you using the very latest daily build? https://github.com/LuxCoreRender/LuxCor ... tag/latest
It might have been already fixed (I had a similar case recently).
Properties > World (Env. Light) is set to HDRI without texture!
That is not a problem, it will behave the same as if "Flat Color" was selected.

Properties > World (Env. Light) is set to HDRI without texture!
That is not a problem, it will behave the same as if "Flat Color" was selected.
With World set to "None" or "HDRI" (as it was set in the file) but with texture, everything was fine.
Just chimed in, of course you sure know more.

With a debug build I get the following SIGABRT crash because of a failed assertion:

Code: Select all

I may have had related issue in Luxcore ui.

As with:

Code: Select all

scene.lights.<light source name>.visibilitymapcache.visibility.radius = 0.0
The radius was auto set to 0.14

Now when i do manual value like 0.014
The scene does not load up.
