So I was doing a ring attached to chains... I've been helped before and decided to start over again... however this time when I animate by alt+a this happened: the ring stays at this angle... I've included the blend file... any help would be appreciated... thx
And also...can someone tell me how to increase the preview animation in the timeline (so that its longer than 250 frames) setting the end frame to 300 doesn't animate it further than 250... it's like the 50 frames were never there...
