Yeah for things like levers its just so simple to handle that its kind of best left up to the end user, the plugin handles all of the gripping for that and the constraint handles all of the limits.
The door is a child actor for only one reason, only root components replicate position correctly with physics and I didn’t want it to be two actors (the frame and then the door). Technically it could probably have been hacked together by using a scene comp to seperate the frame from the door and have the frame be a child component in the doors actor.
However I did make that thing a long time ago, its on my TODO to go back over the setup with chaos out now.
