I am new to Blueprints, so I figure it out that rotating the door would be a great practice subject, so I’ve implemented the same approach that I use in CPP now Blueprints.
I am not going to deep into the explanation here, but if you want to play (and improve) with my approach, feel free!
You just need to the SM_DoorFrame and the SM_Door into the Blueprint root element and create the above graph.
Don’t forget to add the Curve reference to the BP (to create the curve itself, just see the link above from my other post)
