AttributeError: 'LuxCoreScene' object has no attribute 'opencl'

[FarbigeWelt]

Crashs with default or any other scene using openCL in any way.

BlendLuxCore 2.4alpha0 registered (with pyluxcore 2.4alpha0)
BlendLuxCore/commit/066bde9cde2a8549194442d3309fabbd2435b480
LuxCore/commit/240dd579d2fc7a89a21ac648af413377f8e4e59e

With current versions and the ones from the last two or three weeks , rendering is only possible if GPU/openCL is not used for any lux job (rendering and tone-mapping).
For what reason ever BlendLuxCore calls an openCL related 'function' even with all user interface easy accessible openCL related properties disabled.
There is also at least one call short after rendering on CPU only started.

[Engine/Final] Finished rendering layer "View Layer"

The moment render engine is switched from CPU to CPU BlendLuxCore calls several openCL related 'functions', leading to error messages continously logged.
Starting rendering (menu or F12) crashes Blender immediately! Exported scene crashes LuxCoreUI with a short delay without further notice.

It is like if you are using an old version of BlendLuxCore, there is no "ui\render_performance.py" file in BlendLuxCore now: https://github.com/LuxCoreRender/BlendL ... /master/ui

Try to delete the "C:\Users\Michael\AppData\Roaming\Blender Foundation\Blender\2.82\scripts\addons\BlendLuxCore" directory and to re-install BlendLuxCore.

[FarbigeWelt]

Hi Dade
After removing the add-on and deleting its folder completely I have installed the build versions listed in first post in this thread here.
Indeed, the openCL error raised by "ui\render_performance.py" was gone.

Now, the render process crashes with log entry ["[LuxRays][13.984] [BVHKernel] Compiling kernels".
It does not matter if I render with BlendLuxCore or with an exported render.cfg file loaded in LuxCoreUI.
Do you have any further hints helping me to render with GPU again?

Do you have any further hints helping me to render with GPU again?

Does it happen with any scene ? Have you recently updated GPU drivers ? This is usually mean a broken driver.

[Theo_Gottwald]

try to render the Kernels with an empty scene, (just Standard Cube and Plane and 1 Light).
Does it work or also not?

Thank you for answering.

Driver should be okay, because I did mot update it since an earlier well running version of render v. 2.4 alpha.

After I deleted startup.blend GPU | openCL version renders the default cube scene again. Finally! I do not know why. But well, I am glad to have a running system again.

Thank you for the hint.

My default scene was not original. I have set up all BlendLuxCore settings as useful for me as possible, including arranging also its menus more comfortable than default of add-on.

After I deleted my specific startup.blend in one of Blender’s folder Blender reseted the startup.blend.
The default cube scene renders now again on GPU | openCL.

For me this behavior is quite strange.

I hope more complex scenes than the default will run as well.

Regards

[Theo_Gottwald]

Here, I just render the default scene once,
thereafter also more complicated scenes often work fine.
Is it strange?
This is all very complicated stuff and the developers of Luxcore only have it partly in their hands.
There are so many (often updated and changed) software-Interfaces, types of graphics-cards etc. involved,
additionally Blender has a very fast turnaround speed to new versions.

That its not easy to get it "run everywhere" at the firs try.
Yes for the user it may sound strange. But a few revisions later it will all work more easy together possibly.

[B.Y.O.B.]

For the kernel compilation step in v2.4, it should not matter from which scene it is started, because it uses a very simple scene internally.

[FarbigeWelt]

Your piece fits well to the puzzled image.

What happened some day earlier..
My first positive astonishment switched (Gna..) in short time after I checked settings and I had to realize (Gna! ...) that I have been testing with v2.3. (S@&¥.!, F^%#!.., .. What? ..!?)

Meanwhile..
I checked if there was any graphic cardr update lately. Indeed, there was what seems to lay between versions of daily build v2.4 worked for opencl on my system and versions from 2020.06.16.

Outlook..
Deinstall Blender and LuxCoreRender and add-on.
Delete all kernel cache files ( where are these located on a Windows 10 Pro )
Shut down, restart after 10 to 15 seconds.
Install Blender and LuxCoreRender v.Versions

Does anyone have other / further suggestions
