TypeError: collection does not support a 'None' assignment with Khaos

Hello, I’m using this new addon called Khaos for a project, but I’m constantly running into issues. I select the Smoke/Fire and Dirt options, click Omnidirectional Burst, and then I get this error:

Python: Traceback (most recent call last):
File “C:\Users\jerem\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\khaos3_1_install_wdestoolsparticles_v10_init_.py”, line 3869, in execute
bpy.context.view_layer.active_layer_collection = layerColl
TypeError: bpy_struct: item.attr = val: ViewLayer.active_layer_collection does not support a ‘None’ assignment LayerCollection type

location: :-1

It happens about 90% of the time. I thought at first it was my project file, as it worked fine in a new project, but now that I’m playing with it again, it happens in new projects as well.

It creates the elements, but the simulation doesn’t run.

Any idea as to what is causing the error and how to fix it?

Welcome to BA :slight_smile: you will probably have better luck reaching out to the developer of this add-on directly:

Thank you. I have reached out through Blender Market. Still waiting on a response. But maybe I’ll have better luck with this! Thank you for the link!
