Poser - OFFICIAL F.A.Q (Last Updated: 2025 Feb 07 8:53 pm)
Subject: Can someone explain the use of the component node in EZSkin?
This is described in the manual:
The Component node is useful for extracting the red, green,
or blue components from an input color...
0 = Red
1 = Green
2 = Blue
The EZSkin one you described is pulling info from the Red channel - if I remember correctly it's to modulate the way that bump and / or specularity is applied.

Hmmm, so the question is why would they use info from the red channel to control the intensity of the bump & specular? Why not blue or green?
Because skin is mostly red, so the amount of precision in the red channel is greater than the other two. The goal is to detect body and facial hair (which generally is darker than the skin) and not apply skin-style specularity there. This is not a perfect strategy and is only included because the vast majority of skin textures do not include a skin/hair map.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

If you wanted to disable this feature could you set the component to say 5? The only reason I ask is if your texture has no hair on it. Or is it better to just remove the node entirely? Or maybe I should just leave it on if it won't hurt anything?
On a side note, you wouldn't happen to know of a chat room with lots of Poser related 3D discussion and techniques, where everyone is collaborating to improve the quality of their renders?

I'm looking at the EZSkin setup right now. There is a component node inside with these settings:
Component: 0
Color: White 255,255,255
Point: value
The Color part of this node is tied to the diffuse map (V4's body color map).
The question is what is happening here exactly? Is the node trying to extract all the red from the texture? I looked at the manual but still don't quite get it.
