MATERIAL TEXTURE PROBLEM Constant 1 Vector missing in Version 12.5

The vectors that I have avaliable are Constant, Constant2. Constant3 and Constant4 showing up in the pallet all colored yellow nodes…
The Node that is called Constant is only a green colored node (its not colored yellow). So Its not a vector node. I need the Single Yellow Color Constant 1 Vector node but I can’t find it in the pallet or is it been put under a different name?

I don’t know where it is in Version 12.5. I need to get rid of the white eyebrows problem I’m
having in trying to texture this model. The Opacity mask should’ve worked but if I don’t hae the correct constant 1 Vector node
it may not work unless you guys know another way to solve this white eyebrows problem…

Constant is constant. The problem is not in the node color.

Well alright, where have I gone wrong in the setup, this is supposed to make the texture white background become transparent.

Your Constant 1 Vector node is called Constant. Simply because it is not a vector but a float value. And it never had yellow color. Always used to be green.

For masked materials, opacity mask black values define transparent regions, not white ones.
