Looks good.

And I agree about shoulders being the most difficult. And that's not all, unfortunately multi axis JCMs can also be very hair pulling to set up and more than likely you'll need them for shoulder rotations. The scaling math can get pretty confusing and you'll need ValueOps to set it up. While the relations between a JCM that effects 2 positive rotations is tricky it becomes almost unbelievably confusing setting the scale values for a JCM that works against both a positive and negative rotation. I still haven't managed to get such a JCM to work properly, but I haven't bothered to post a query to the technical forum in hopes of getting Nerd to answer. He's probably the only one who can answer such a problem. My math mojo isn't up to the task it seems... even framing such a question coherently is a bit of work. Fortunately for the simple weightmapping projects I've been playing with I've been able to fix things with weight painting alone. If at all possible try to solve the most you can via the weights, it's much more artist friendly than diving into complex valueOps.

When you get to that point I really recommend finding a maths guru to help you setting these things up.

Best of luck Shane.

Well I'm pretty much there now but I don't think I'll have to do too much valueOps monstrosities, trying to keep things as simple as possible so its easier to rig clothing for. I think between that other thread you linked in another thread some months back where Chuck explained things and the help of PFE it shouldn't be too much of a nightmare. I do have a calculator.

Things like valueOps should be a series of button clicks by this point. Set the joints where you need them, dial the morph to 1 and let Poser do the math. Why isn't this a thing?

It's a little more complicated than that, even with a scientific calculator. It's the scale factor for 2 value ops, an add and a multiply. If you don't know the proper formula the calculator is of no use. Unfortunately the response in that thread seems to only work with 2 positive rotations triggering a JCM. Very easy. A positive and negative rotation? I haven't been able to solve it, and I've been over it and over it in various permutations. Anyway, I don't want to bother Charles with it... if he would even respond. I'm not exactly fondly regarded hereabouts lol. It's a small pool ;)... I make do.

"Set the joints where you need them, dial the morph to 1 and let Poser do the math. Why isn't this a thing?"

Amen to that last bit.
