Restoring figure after ERC freeze

knuckledusterharris_b01188de76

I created a morph via zbrush go-z, applied it to a figure, adjusted the rigging (this was making arms longer, adjusting hand, forearm, and upper arm joints), then did ERC freeze on the morph. When I slide the morph back to zero, other bones move as well--everything back in the chain all the way to the pelvis move. How can I isolate the ERC freeze to just the joints I want?

Was it a standard figure? If it was a newly created figure, you need to memorise the rigging before adjusting to shape or DS doesn't have a starting point.

I created and rigged this figure about a year and a half ago. Most of my morphs are faces, so I rarely do proportions, requiring moving bones around. It always works well GO-z from zbrush to daz, applying the morph in Daz, and saving the morph for future use. This time I was making my arms longer, which meant moving hand bones (very tedious).

I set up the new bone locations on the morphed figure, then go to the ERC freeze menu (I'm having trouble understanding what the variables mean in the menu, so I'm kind of lost there--all the instructional material I found seems to reference an earlier version of the menu--I might be missing a key web page I haven't found yet).

When I test out the slider after doing the ERC freeze, and slide back to neutral on the morph (zero), other bones besides the ones I changed also move--they contract and drop down as well. It's as if I had increased the size of the whole figure when applying the morph, although I didn't, and it wants to go back to some smaller size that never was there.

Adjust rigging to shape moves the end points of the bones so they line up with the same bits of mesh as they do in the base state. ERC Freeze compares parameters with the base state and adds a link to the controller so that when the controller is at 1 (or at the current value when ERC Freeze is run, rather) the properties will have their current values. If your joint settings are not in their memorised base state then ERC Freeze will see the differences between base state and memorised state as part of the changes it should be linking to the morph, and when it restores the figure it will restore it to the memorised state not the actual state on load. You must memorise rigging before using these features.

When you say memorized, do you mean saved? I have been working with the same saved figure in my library for a long time. 

I revised this figure to be a bit larger at one point; now I have two versions of it. This is the larger of the two. When I load them and look at the bones, they're lined up properly on both versions relative to their shape by default. I've been using the larger version for all my sculpts for a long time with no problem other than this. Is there an additional step I should have done to make sure the bones in the larger version are baked in?

ps the amount the bones shift when un-morphing are about the same amount as the size difference between the two figures.

I remember that now from when I first rigged the figure. Thanks!

Works like a charm. And the auto adjust rigging to shape feature worked well when I ticked off the boxes for the face groups and bones I wanted to adjust--especially helpful since I was making the arms longer and had finger bones to move. Excellent, thanks for your patience.
