I can’t imagine I just change that 1, 1, 1 vector to be the center value using math, right? Surely that will mess up the location to coordinates calculations, no?

The white balls are the points that are mapped. The yellow sphere is the object’s location. And while it is technically the origin since all coordinate values are positive, I need it to be the center.

actually, the math is wrong. The formula you were trying to use is to get the midpoint between two points, so you were supposed to add, not subtract their vectors
