Blender luxcore clashes on blender 4.2 for linux (popos 22.04/ubuntu 22.04)

blender.crash.txt

Hi, i like so much luxcore and i've been working with it since blender 2.79. But i am having a seriously problem.. i am stuck with luxcore in blender 2.93.. i tried it on blender 3.6. but it didnt work, so i said its ok and i will still use it in 2.93.

But blender made a critical shift between 3.x and 4.x. so in case i want to use luxcore which is 2.93, i have to save the file from 4.x to 3.6 so i can use the .blend file in 2.93 (which is the only luxcore that actually works for me). so when i knew that there is the alpha for 4.0, i downloaded it. the installation was good, no trace call error. but when i hit render blender 4.0 luxcore crashes.

as for the luxcore3.6 and why i dont use it, because when i hit render i cant see the objects (meshes), its only a sky texture (the one that luxcore already has).

the report inside blender.crash.txt:

Are you tried also rendering using CPU instead of GPU?

hi.. yes .. it crashes also on CPU.. i used it on 3.6 and it crashed (because i have reinstalled it after reporting the issue)

hi again... i tried it on 3.6.. but still crashed.. steps i took:

• removed the old blendlux addon (beta)
• restarted blender 3.6.11.
• reinstalled the blendlux addon (beta2) the one you provided.
• switched from EEVEE to Luxcore for the Render engine.
• in the viewport scene, only a camera and the default cube are present with no light.
• clicked on the Render button (located at the top right of the viewport).
• crashed suddenly.

Hi. If you still have an issue download:

Blender 4.2+
https://github.com/LuxCoreRender/BlendLuxCore/releases/tag/blendluxcore_v2.9beta1

Blender 4.1 (not 4.2)
https://github.com/LuxCoreRender/BlendLuxCore/releases/tag/blendluxcore_v2.9alpha1

Blender 4.0.x (not for 4.1)
https://github.com/LuxCoreRender/BlendLuxCore/releases/tag/blendluxcore_v2.8alpha1

Blender 3.6 LTS (3.6.1 or so):
https://github.com/LuxCoreRender/BlendLuxCore/releases/tag/blendluxcore_v2.6alpha1

it's really weird... in 2.93, it works flawlessly... so for later versions, what changed - it should be the same unless the code changed which means the code should be rewritten in conjunction to 2.93 luxcore addon's code . the issue won't be fixed by installing the newer versions luxcore addons. and honestly i don't believe there will be any fix for this.

From what I can see you have not installed a couple of other addons too.

1. Reset Blender to Factory settings
2. Install with unpacking BlendLuxCore folder to "scripts/addons" folder instead of Install from Zip (if it has not here already)
3. Enable an addon
4. Try to rendering with CPU not GPU (your Nvidia 920M GPU is outdated I guess)

For 3.6.x you must install this:
https://github.com/LuxCoreRender/BlendLuxCore/releases/download/blendluxcore_v2.7beta1/BlendLuxCore-v2.7beta1-linux64.zip
