Don't worry, I had the same problem. I got a little symbol next to the cursor which seemed to suggest the dial was being dragged, but I couldn't find anywhere that it would drop. It could be a Poser Pro feature?
Ok, just a brief overview of the text approach due to time pressures. I'm assuming you've delved about inside CR2s before, and know about stuff like keeping the opening and closing braces matched, and of course make a copy of whatever you work on in case it goes wrong!
Here's a value parameter dial, in this case from V4's Body channels. You could cut and paste it into the channel stack for any other actor.
valueParm SCLHeadSize
{
name HeadSize
initValue 0
hidden 0
forceLimits 1
min -0.5
max 1
trackingScale 0.004
keys
{
static 0
k 0 0
}
interpStyleLocked 0
}
And here's the scale section from V4's head, which is one of the parameters that SCLHeadSize controls.
scale scale
{
name Scale (xyz)
initValue 1
hidden 0
forceLimits 0
min 0.1
max 100000
trackingScale 0.004
keys
{
static 0
k 0 1.05
}
interpStyleLocked 0
valueOpDeltaAdd
Figure 1
head:1
SCLHeadSize
deltaAddDelta 1.000000
}
The valueOpDeltaAdd section is the part that does the work:
head tells it where to look for its controller - change this for the name of the body part where you've moved the master dial.
SCLHeadSize is the controller's identifier - note that this is the part after the valueParm statement and can be different from the name on the dial, as it is in this example.
Of course, in the usual case where one master controls several actors, you would make the change in every affected actor to make sure they all look in the right place for their controller.
There are many more permutations, but I'll avoid over-complicating things at this stage!
Sorry this is brief, but let me know if it helps - and if it doesn't, where I can explain further.
