I'm trying to make R2D2 move along a path on a curve, but I'm having trouble making sure he conforms to the physics and shape of the path. As you can see in the screenshot, it's hard to make him adjust to the shape of the path without sinking into it or floating over it due to the height of the curve and the difficulty in matching it to the path's shape exactly.
I’ve tried duplicating one of the edge loops of the path mesh and then converting it to a curve, but for some reason it sends whatever you parent it to flying into outer space. I also used constraints (follow path and locked track) but still it makes the empty and R2D2 fly everywhere and warp. FYI, I also scaled everything so it’s not that issue either.
What I’m wondering is whether or not there is a very simple way to make sure your character gets from one side of the scene to the other while respecting rigid body physics?
