Hi, looks like you are getting popping because the mainaxis parm for the strech is set to X, it should be set to the axis that faces down the bone. In most cases this would be Z.

That should fix it.

I've attached another way of going about it, based on Will's Chicken and Lucha rigs.

@william_harley what I'm using here is the blendshape method, where you treat the points like geometry and while looping through each joint. Is there a benefit to using the skeleton blend over the blendshape node?

Technically the skeleton blend is pretty much doing exactly what I was doing in the chicken and luchador setup. The big difference is the pre setup. With the skeleton blend you don't have to worry about managing the skeletons like I did, you can simply add them to the folders and plug them in and it will work.

Whats nice about apex, is that you are not limited to using specific tools to achieve a task. You should feel free to get creative with building your setups. I do think some tools are better for specific tasks, and the skeleton blend has been developed specifically for this and should preform better.

Hi there, here is a file showing how to set up skeleton blendshapes in apex.
hope this helps.

I have just done this in a simple edit graph, so you can get a better idea of what it needs to look like.
