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...
