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).

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.

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

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.

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Try to rendering with CPU not GPU (your Nvidia 920M GPU is outdated I guess)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

Dec 12 '24 17:12 odil24

ok.. i downloaded v2.7 beta and installed it and rendered on cpu, same problem.

I'm on Linux, It will be grate to have a blendluxcore for blender 4.2. What is blocking you ?

Dec 22 '24 22:12 lastrodamo

Closing this issue as a leftover concerning older (alpha) version of BlendLuxCore.

In the last year, a new stable version was released (v2.10) which supports Blender 4.2-4.5. Linux compatibility is also restored.
