I have a model that I'm trying to offset on the X axis. The model is separated into two different vector groups. I want the left half of the model to move in the negative direction on the X axis while the right half of the model moves in the positive direction. Ideally I would be able to control all of this with one slider.

Is there a way to invert the value of one of these nodes? I want them to always be offset by the same amount, just in opposite directions.

Is it possible to link these two vector math nodes together somehow so that when a slider is used, one vector is offset by -1 while another is offset by +1?

There are many ways to do this. One flexible way that I like is to use an Input node for the slider. Feed it directly to one of the Vector math nodes. Feed it to a Math node set to Multiply and use -1 as the multiplier. In this version I've added a combineXYZ node for flexibility:

Node group described above

This way, the Input slider directly drives both Add nodes but in opposite directions.
