Heya everyone!
First post! YAY 
hate to start my first post with a question, but here goes. What I am trying to do:
- I want to dynamically fill the drop down list with the available scene collections. This works!
- When I select a different object in the scene, I want to highlight/select the collection the object is linked to in the drop down list.
- When I select a collection from the drop down list I want the object to be linked to the selected collection.
I can’t figure out how to change the currently selected item… In c# you can just do this
var_enum = MyEnum.State; But this does not seem to work here… If someone can point me in the right direction, it would be much appreciated.
Thanks!
