hi…
how to stretch it ? in edit mode or pose mode ?
plz guide . thank you.
You’ll want to move that joint in Edit Mode.
You probably also want the lower arm to be parented to the upper arm with the ‘Connected’ option.
Edit Mode…you don’t want the bone to possibly animate stretching from Pose Mode.
You want to stretch the Upper Arm Bone down to the elbow crease for the arm to bend ( Remember to turn on Mirroring) if you grab the lower part of the top arm bone it should automatically shrink the forearm bone…if not just use snapping to get them back together…
