LuxCoreRender Forums

Hello!
I encountered the following problem: when I install Luxcore, everything works fine, but when I exit Blender and re-enter, a number of add-ons “don't work,” as if they weren't enabled. But they are enabled. Luxcore is lit up as activated, but it doesn't work until I uncheck it and check it again. And if I exit Blender with Luxcore left enabled, the problem persists. If I exit Blender without saving the add-on activation and re-enable it when I re-enter, it works.

One more thing: in the material settings, I copied the Lux nodes and pasted them into another material, and a Blender error appeared, and Windows displayed a black screen with an error saying that the hardware needed to be fixed and restarted. It's hard for me to say whether the problem described initially existed before this event, as I tested it yesterday for the first time and today for the second time.

Copying nodes closes Blender now, but that's not my main question.

This is the case in both 4.5 and 5.0.
2.10.2

Hi,

Are there any (error) messages printed in the console during the startup of Blender?
If you don't know how to open Blender from a comman line, on Windows you can open the console from within Blender thorugh the Menu "Window -> Toggle System Console". Please share all the text shown there. You can censor your user name in file paths if you wish, or send it to me in a DM.

Regarding material copying, there was a similar sounding report recently, for which another developer already created a fix that will be available in the next version 2.11: https://github.com/LuxCoreRender/BlendL ... ssues/1026
Maybe it can be applied to v2.10, I'd have to try and reproduce the error first.

A complete system crash of Windows is always strange, but usually implies some underlying driver problem, as by the design the operating system is supposed to separate applications in such a way that this is not possible.
What are your system specs? CPU, GPU, and GPU driver version?
Let us look at the errors with the addons first and see if this persists.

A note: Blender 5.0 is not fully supported by v2.10.2 (we noticed more API changes that need adapting), so I would stick to Blender 4.5 for testing.

Hello!
I will look into it and send you what you requested. Right now, I want to roll back the drivers from 591.44 to 581.57 because Vray is behaving strangely on the GPU, and the drivers mentioned above are the latest verified ones.

Oh, I also got the Windows error again, it said something about a device/driver (black screen, white text). And I think it was when I clicked on materials to make the material unique for the object.

Thank you! Have a nice day!
I will provide the next information soon.

Hi,

I have checked about the node-copying crash. Indeed, I can reproduce it with Blender 4.5.5 and BlendLuxCore 2.10.2.
In the latest v2.11 development branch, the crash doesn't happen anymore. I will have to go back to check what change may have fixed this, perhaps I can make a 2.10.3 release until 2.11 is out. Lets see.

About the other addons problem, I suggest to follow up with what I wrote you in DM.
