So I made a ragdoll horse in the Game engine using an armature and some hitboxes. I connected these hitboxes with Rigid Body Joints. Now I want to use this rig for animation. However, I animate with Cycles. I know that the Rigid Body Joint does not work in Cycles, and the Rigid Body Constraint set on Hinge in the physics tab doesn't do the same thing- it just stays rigid and doesn't swivel. Is there any way to get the same effect that I get with Rigid Body Joint, but in Cycles?
The game engine rigid body joints do not work outside the game engine. For similar behaviour in Cycles you should use Rigid Body Constraints - these can be created by selecting two or more rigid bodies and clicking Connect in the Physics Toolbox panel (T). When a rigid body constraint is first added it defaults to ‘Disable Collision’ - to enable collision between linked objects you should untick the checkbox in the Rigid Body Constraint physics properties.
