Thanks! Yeah, I’ve tried binding the door to another bone, and even setting up the skeleton so that there’s a root node, then belair/chassis, then door a child of the Belair/Chassis. So it wasn’t under the root directly.
I’ve also tested/setup the trunk as a socketed attachment, which is a skeleton. Then tried using 1 and 2 bones in the trunk skeleton, and doing various tests as noted above.
I can take a look at the advanced one. Hopefully I can get it to work. Does the advanced version swap between kinematic and simulated states? I would like to have the door “static” so I can animate it and not be always simulating , then when its open/anim end, start the simulation.
My plan though is to break up most of the parts into static meshes or skeletal meshes and attach to sockets. The only issue I had to solve yet is the simulation stuff.
