I’m in a situation where I would like to have a mesh follow a bone, but still lay flat on the ground. It would be nice to only bind x and z to the bone.
Can it be done?
Hello 
Short answer is “yes”, but it will be “manual”, I think there is no function to restrict the attachment of a mesh to a bone with only one axis.
By “follow a bone” and “bind x and z” do you mean only positionning then ? No rotation ?
I think “no rotation” is what I mean (although rotation would be involved up the chain in the bone hierarchy).
Basically I would like to bind a mesh to follow the average x and z position of a bi-ped skeleton’s two feet so that it’s always flat on the ground, following the skeleton.
Right now I’m doing it by updating the position manually but I thought it would be cool to try if it was possible via skinning.
