Error when creating lightstudio

[Anon35236263]

I have a lot of problems with LLS version 2.15 and blender 4.0.2, I can't edit anything in existing profiles because the program closes, I can't delete or create, the only thing that works is switching between previously created profiles :/

This problem occurs when I try to create a new LLS, the error I pasted appears and copies of objects are created, I manually deleted everything from the file related to LLS, restarted blender and still the same.

Hi Anon,

LightStudio has an issue with Blender 4.0+ and we don't have a solution for it yet.

Hello, I downloaded version 2.15.1 which is supposed to fix problems with Blender 4.0 and when I create a new file everything works, but I wanted to add LLS to an existing project in which version 2.15.0 did not work before, the error has changed a bit but it still works the same. When creating the LLS, the attached error appears and an empty copy of the LLS is created, in addition, the "Lights" tab is displayed in the N panel, even though the LLS does not exist, in the new project this tab is not there before the LLS was created. Is there any way to fix this project? I removed everything related to LLS from the file, reinstalled the addon but nothing helped.

I can't replicate your problem. What do you use for chat? I can remote in and see if I can fix it.

I'm in PST timezone.

Unfortunately, I have not been able to replicate your issue. However, please try removing everything LLS related from outliner (with Blender File display mode)

Then please run this script in text editor:

import bpy
bpy.context.scene.LLStudio.profile_list.clear()
bpy.context.scene.LLStudio.profile_list_index = 0
bpy.context.scene.LLStudio.light_list.clear()
bpy.context.scene.LLStudio.light_list_index = -1
bpy.context.scene.LLStudio.initialized = False

After this, hopefully, you will be able to create a fresh LLS.

I ran Windows Sandbox to check if the file was corrupt on a clean install and it appeared.

Virtual machine -> Blender 4.0.2 downloaded from blender.org -> installation of LLS 2.15.1 -> it works in the new file -> I restarted blender -> I opened the attached file (there are only cameras in it, I removed the rest of the unnecessary things) > the problem is same

I hope this helps remove bugs :)

I did this by trying to fix the error myself, but

import bpy bpy.context.scene.LLStudio.profile_list.clear() bpy.context.scene.LLStudio.profile_list_index = 0 bpy.context.scene.LLStudio.light_list.clear() bpy.context.scene.LLStudio.light_list_index = -1 bpy.context.scene.LLStudio.initialized = False

This fixed my file :) Thank you very much for your help! Great addon!
