I am getting the same buggy results.
I found a way to get some of the deforming visible in sequencer, but as soon as you try to render everything goes back to default…
In the vehicleBP try to find the skm_ (theres 3 meshes i guess) meshes and set the visibility to true… just need to figure out, how to get it to render properly. If you find anything, let me know!
cheers
