I am working on this medieval flail. As you can see in 3dexchange the hierarchy is intact and each link is a separate object.
The idea is each link is its own object to be made into a rigid body. I exported this from 3d Exchange as an iProp and look what happened...

...the separate objects merged into one. I know I could save each link as its own iProp and line them up in iClone but that is too time costly for repeating each time I need to use a flail. Is there a way to keep the hierarchy intact for an iProp? Or a way to add the rigid body to each link in 3d Exchange?
