In either the Principled shader or SSS shader, there is a value that seems to take in RGB values that you input and uses them to change the size and color of the scattering, called “Radius”. This value appears like it would be far easier to control if you were simply able to select a color through the color picker, then adjust the size/distance of the scatter separately. However, even though there is an input socket available, it doesn’t really like it when you plug something in.
So, my question to you comes in two parts:
- Is there a way to control the Radius values as stated?
- If there is no way to control it externally, why have an input socket in the first place?
My current progress:
As you can see, the size can be increased this way, just not the color. No matter what I set the color to, it doesn’t change. Also, this only works with the Principled shader, the SSS shader won’t be effected at all. I’m completely willing to accept that I have no idea what I’m doing.
Any help would be great!
