I believe I’m experiencing the same issue. I have a camera rig with a bunch of nodes setup and I would like to bind the boom offset to a variable in the camera variable collection I created. I am able to access the collection through blueprints but not in the rig editor. When I click on the 3 little diamonds the camera rig editor does list the collections I’ve define but doesn’t show any of the variables I defined.
I read the solution was to use the Get Initial Variable table call but I don’t see that anywhere as others have reported
