@jgonzalez Thanks for your reply. The “introduction to python scripting” course, I already took a look at. And since I do have some python experience already, I thought the course was slightly too simplistic. The other two, I only looked at briefly. I will go through those courses too, eventually. The “scripting a custom rig ui add on” is the closest to what I’m looking for, though. But again, seems a big short and more focused on scripting the rig. I was hoping for more in depth stuff, going through the entire process of creating an add-on, different options etc. But if as you said, that something is perhaps in the works already, I’m definitely looking forward to it!
