Hi,
I understood joint control morphs to be applied according to the bending dial they belong to. However, I recently investigated a figure that showed (after making the local JCM's visible) JCM's that indeed had local values > 0.  Because the figure was generated, I am wondering whether this is an error in the figure; but I do not know the common practices regarding JCMs.  My assumption was that figures are designed in the zero pose, where bending dials are all 0.0 and JCMs also.
Maybe someone can comment?
Thanks a lot.

The initial value for slave dials doesn't have to be zero.  In human figures it usually is zero,
but there are lots of mechanical things like venetian blinds or folding tables, where the
ERC function depends on having exactly the right starting point for each slave.

That makes sense. I wonder if there is a good ERC tutorial around that one can read? I was also unsure about ERC and limits. It appeared to me that poser takes local value + erc value and clips this with the limits. The local value must also comply to the limits.

Maybe there is also freeware tool that can display/dump the ERC setup of a figure? I still wonder about the ERC setup of the DAZ4 figures. I noticed that if you do a menu->create_fullbody_morph in the poser gui while a morphform is dialed, the morphform is "partly" added into the fbm.  One is set up to be morph target, one is just an ERC dial, but they are slaved 1:1 as far as I could see. The dial on the BODY actor and the dial in the BODYMORPHS actor get different values then, because only the morph dial is added to the FBM. Poser appears to be unable to properly safe such a pose to the library then. It stores different values for something that tries to be the same through ERC. Interestingly, the wrong value of the BODYMORPHS morph is copied back to the master dial in the BODY actor. Why this is I could not figure out.
Can slaving be bi-directional?

On limits:  Yes, the local value is mixed with the ERC value and then clipped.  The
final number on any joint will never go beyond its own Max and Min.   (Assuming the limits
are turned on, either by the menu command or by "forceLimits 1" in the CR2.)

On Vicky and friends:  the ERC is indeed hard to follow and tricky to save.  Part
of the action happens outside the main CR2.   I don't know much about Vicky...
most likely LesBentley will pop in here to explain in better detail!
