same, im making a game where you play a dragon so I really need to be able to have quite advanced collisions on it as wings can go right out and it can change position a lot.
If I use skeletal mesh as root I can have quite advanced collisions but A it turns into a rag-doll and B it falls even when gravity is turned off.
other option was to have multiple collisions under root but it seams like only root can collide with anything.
