I just wanted to see if Blender could do this : greyscalegorilla.com/blog/2011/10/make-dynamic-chain-mail-in-cinema-4d/
Obviously, it can 
- Pretty cool !
(Render with Cycles)
Always nice such stuff. :yes:
I guess you had to set the ring (before multiple cloning) as triangle mesh collision bounds?
Actually, this is quiet easy. I used a cloth simulation and a particle system. There is a little bit of tweaking to make it work but nothing that difficult.
I may make a tutorial someday if I found the time.
