Is it possible to save properties to grease pencil data?
bpy.data.grease_pencil[‘GPencil’][‘prop’] = my_prop is working for the current scene but once I reopen the file after Blender was closed, the property doesn’t exists anymore.
I’d like also to do something similar to GP layers. Is that possible?
I’m also facing this problem. I try to create custom properties into GPencilLayer() and it seams that this feature is not supported. I think that this should be supported and if someone could point me into right direction, I could try to code this into blender.
