pete Could the order of the constraints be incorrect? Just to be sure, when I show the rig featured in Arman's video (I have it because I purchased that Spine project before!) in 4.3-beta, it looks like this:
Please note that in 4.3-beta, using Clamp expands the range of more automated motion settings. If I were to create a leg rig using the features in 4.3-beta, I would create something like this:
In the rig shown in the video above, when moving the hip bone below its default position, the knee bends and the leg extends or retracts. When moving it above the default position, the entire leg lifts upward, preventing the foot from unnaturally stretching.
I've attached the Spine project here with all image attachments removed, leaving only the bones and constraints:
I hope this will be helpful.
