How can I invert the value range of a node group's input node? I am making a simple edge detector group, and I want to expose a value to its input. The only problem is that the value I want to expose is mapped differently than I would like. It goes from -1 to +1. I want to create a slider that controls this value such that the slider goes from 1 to 0 (backwards) instead of -1 to +1.
Here are images:


Hopefully this makes sense.
So I found the solution pretty quickly! I just needed a &quot;Map Range&quot; node.
Here's a link to the documentation:

Hopefully this will help someone in the future.
