I am making a Rube Goldberg machine in blender and am using rigid body physics for it. My issue is after my ball (an active rigid body object) bumps into dominos which fall down (active rigid body) it pushes a lever on a hinge (with the hinge constraint) which is supposed to release another ball however this ball is floating on the surface which is a passive rigid body object but it should be on the it.
The first image shows how the ball which should be released is just floating. I have tried moving it but it just goes back to this position and I have tried applying all transformations but then it just does something really weird; it just breaks down.
The second image shows how the dominos are also floating but they do fall normally however I have tried moving and applying all transformations as well. The base which all the objects are on is a plane which I changed to shape and is a passive rigid body object set to mesh.
One last thing; I can't get the hinge thing to only move once the domino hits it, I have set the origin of the lever part to 'centre of mass' and this sort of helped but it still moves before the final domino hits it. And lastly, for some reason the dominos jiggle at the start of the simulation. If you have any ideas please let me know.
