Public parameters in functions (Pixel Processor) for Substance Painter.
Hello!
I'm new to using Substance Designer, unfortunately I'm stumped.
I made a node tree:

I built a node called "Pixel Processor" like this:

In Substance Painter, I need to change the "Float" value in this tree (red color).
How can I make this number "FLOAT" a parameter available in Substance Painter?
If this problem requires rebuilding the tree, then how do I change it?
For surface nodes (not in functions) I can click on "Edit exposed graph input", but there is no such thing in the function editor 😞
