Blender version 2.93.3

Pressing F and clicking on any mesh produces this error:

Hello,

What version of LightStudio are you using? The latest version is 2.9.2 and I can't reproduce the error with Blender 2.93.3.

Greetings, after testing on another computer, there is no error using the light brush... May be an error with python then, I guess I'll have to debug it somehow. I'll try tomorrow and close the issue if it's not affected by the plugin

[leomoon]

Do you have any other plugin installed? Maybe there's plugin that LightStudio is not compatible with.

Sorry for the long waiting time, but I figured out what the problem is. To replicate: Part 1 - set up a simple library file

1. New blender file, delete everything but the default cube
2. Create a new empty
3. Parent the cube to the empty (the empty should be the parent)

Part 2 - set up the file that will use the library file for instancing

1. New blender file, delete everything
2. File -> Link -> link the collection from the Part 1 file
3. Light Studio -> Create LightStudio
4. Add a light
5. Open LightStudio Control Panel
6. Select the light, press F
7. Try to select on of the faces of the linked cube
8. Get error:

My guess is that the plugin is trying to get the normal of the selection, but the selection is an empty, so it doesn't have them. Mind you, this doesn't happen if the model is not linked(if you try to select a normal of a model that is parented to an empty in the original file, the Light Brush works)

I don't know if links work by zipping files, but anyway, here's the minimal setup(I do suggest you try doing it on your own just in case): LightStudioTest.zip :

this is fixed in LightStudio 2.10.0
