It works fine as expected. You have something wrong, try to reinstall both Blender and LCR

There seems to be a problem with geometry export on Linux.

I tried everything to fix it but nothing works. When using CPU computing, only the HDRI appears, while rendering with GPU computing displays the geometry, but with an opacity of approximately 50%. Please refer to the attached images for reference.

Furthermore, I've exported the project to LuxCore standalone, and everything works perfectly—no opacity issues or missing geometry.

It doesn't seem to be a problem with geometry export, as the geometry is present when using GPU computing, but with reduced opacity.

.... try to reinstall both Blender and LCR

I did but not changes.

Any Idea?
thanks

Hi,
I did more test using also old blender 2.93 with Blendluxore 2.6. With this combination all work well. no hide or dissolved geometry. It works very well with this combination.
Just for clarify, for all test I used gnome with Xorg, not Wayland.
I also modify the first post inserting all version of fedora, blender and blendluxcore used in the tests.

Any idea?

Thanks
