Hello community!
This is my goal:
- Create a list of all elements (of a linked model) based on the categories of that model.
I am a beginner in python but here is where I am thanks to @jbenoit44 @Julien_Benoit1 and his custom node “Element.GetFromLinkedFile”.
The main question is: how can I edit this python node so it accepts a list of OST categories?
I found this great post but I don’t know how to connect the dots. Thank you all!
