Quote - Got a couple of questions

Whats with the JCM valueParm's, average Joe isn't meant to be able to play with JCM's directly, especially not ones in the Body of the figure.

What exactly does valueParm One do, I know that the scale dials in each joint are ERC'd to it as are a couple of JCM's, but I see no reason for it being there.

You're not alone. I got the exact same questions  from the person who modified the CR2 for use in Antonia Polygon - Standard. :-)

 

The JCM valueParms in the body:

Development tool, plain and simple! It's much easier to treat the JCMs like normal PBMs and slave their master to the joint movement rather than fiddle with each channel individually. One can load alternative JCMs for the same joint and switch them on the fly, modify the strength, etc.

I guess for average Joe, a possible application of the channels would be to dial down a JCM if it leads to poke-through in some clothing that doesn't have the JCM, or something like that. But mostly, it's meant as a development tool.

I'm not entirely sure why I put them in the body, but I think it was because Poser has some restrictions that can bite you when you do multi-level  ERC like that. The body is usually the best place to put intermediate channels.

 

The One channel:

Sometimes one needs to add (or multiply with, etc) a constant. The simplest example is a scale dial which is at zero for the normal size (100%), positive values  for larger and negative values for smaller. You take the dial value, add 1 to it, and voila, you get the desired scale value. That's what the One channel is for. Poser does not have an ERC command to add a constant, so one has to introduce a channel with a constant value.
