Question by ngerbens · Dec 24, 2019 at 05:24 PM · collision physics collider root motion root bone

Collider attached to (root animated) bone causes extremely dragging movement.

I'm working on a rolling cube (done with Root Motion).
When I put a box collider on my main cube (parent) the cube rolls fine, but the collider is not animated. When I attach a box collider to the Root Bone, the collider rotates perfectly, BUT suddenly the cube almost doest roll forward (keeps rolling in place) because a great amount of friction.

I tried to solve this by adding a Physic Material (friction turned to 0) which helps for making it move forward again but this turns my cube into a feather (physically wise).

Does anyone have a solution??

It has something to do with the RigidBody. When I set FreezeRotation to TRUE, the cube rolls perfect again (with the collider). But unfortunately physics do not work when the cube enters a hill or angled object. Right now I switch FreezeRotation on (when rolling) and off (when standing still). Still hope someone knows how to set this up properly...
