Can’t find One Minus in BP, is that because it’s not there?

It’s not there. You must do it the hard way

What Everynone means is you just multiply your value by negative 1 float and you get the same result

What exactly are you trying to do?

This ^^^ but multiplication would not work well here. The hard way equivalent in question:

But I believe espr3ss0 is well aware.

I thought a one minus node was just inverting a value like converting 1 to negative 1.

The closest I could find is Map Range, with One Minus 1 becomes 0 and 0 becomes 1.

Been looking through some game programming vids on Youtube and is mentioned but not found how yet.

It’s just this, mate:

Thanks but not seeing how to implement it?

Plug what you need where zero is. That’s 1-x

But that’s not even how 1-x works…

It’s just the reminder of 1, so if X = 0.25 the remainder is 0.75.
