Um, colour me a bit thick, but... I've just loaded the VSS_TemplateSkin_PR3_WIP.mt5 and I'm trying to figure out what to hook to what. In the previous version there were nodes with a 'PM' prefix right up against the left-hand border. This node arrangement looks a fair bit different, with the nodes all higglety-piggelty all over the place.

I mean, they work a treat! Synched, rendered, WOW... and no nose-glow, BUT, now, reading this thread, I'm wondering if I did something wrong setting all this up. Here's what I did.
Deciding to start from scratch, I loaded my figure, loaded the textures, loaded VSSPr2Test (even though in the props list is still says VSS_1... that '1' must be an incremental number) and then I loaded VSS_TemplateSkin_PR3_WIP.mt5.

Was this wrong? Did I leave out a step?

If I did this correctly, I've got another question... in the previous sortie of your shader, Bill, I connected my Lip_Blender node to PMC:Color_Tint and the Math_Add for the lips to the PM:Shine node. I've been having a very close look at this new U-Beaut shader but I'm at a loss what to hook to what.

For instance, your PM:Shine output to Pow (.97,50), which output to Mul, which output to the eccentricity input in Blinn, which fed the Value_1 input in Color_Add_2, outputting to Color_Add Value_1, output to Color_Mul_2 Value_2 which fed Color_Pow Value_1 which connected to the Alternate_Diffuse channel in the Poser_Surface main node.

Is that right?

Now, looking at your PR3 and working backwards from the Alt_Diffuse input, we've got:
Color_Math_2 (Pow)... okay, I can follow this on out... Value_1 is fed by Color_Math (add).

Oops. Come aground. Previously, this was a multiply.

No matter, I'll just go by the input channel (Value_2) which is hooked to Math_Functions_3 (divide) which ... nope, a completely different clinical picture. This isn't going to work. Can't just follow node trails around and expect to find the analogous node to connect to: have to know exactly what node is doing what, and how they inter-relate.

Back to remedial nodes class...
