So basically i'm trying to do a ring attached to small chains... However when i press Alt+A to animate, the "ring" detaches from the two bottom "chain" Mass of "ring" = 30kg Mass of each chain link = 4kg... Scale are x= 2.376m y= 1.422m and z= 28.431 I learned the chain thingy from Blender Guru and he said something about the object being big...i'm not sure Also the top 2 chains(left and right) have Active Rigidbodies but arent Dynamic, the rest is dynamic (even the ring) Someone help pls... enter image description here

    it may be related to subdivisions, or bounding shape, solver settings... having the file would help us to help you better (if you wish so, use http://blend-exchange.giantcowfilms.com/ then paste the provided link into your question or in comments) – m.ardito Oct 17 '17 at 21:11

thanks for the file, it was easy: it's the unapplied scale for all chain rings (even the bigger one). They all have some scale like 1.846...

applying each (with CTRLA then "scale"), it becomes 1.0 and it behaves well...
