Trying to get a color ramp across a rectanglular polygon,
Where the center is white and the edges are red.
I'd like to them base the red's thickness based on polygon size.
Should I be diving into VEX to accomplish this.
Thanks!

Because its a rectangle, I could try a bounding box
or centroid, but would still want a look-up to a color ramp
of some sort.

vops would be the way to go imo

Originally wanted to make the white portion square instead of circular, but I'm still failing at this.

Instead, I was thinking I could make the circle look better on a rectangle if I could increase the short side (width or height) by the ratio between the two. This would stretch the circle into an oval to better match a rectangle instead of a square. Just not sure how to do this with distance. My attached file has the ratio ready but nothing to use it with. I think I need a smarter distance that adds overall height and width into account.

Thanks again for your help.
I understand the file better and where the color is coming from.

I've figured out a way to stretch the white circle by expanding the Z point position by the height/width ratio of the rectangle. I can do this procedurally but if the rectangle is taller than wide, I'll need to set up an if/then or something to differentiate between the two. In this later case, it will be increasing the X point position. Not quite sure how to do this yet.

I'm trying to make this VOP SOP works for a set up random sized rectangles so they all have the same color fade no matter it's size. I think I'll need to take into account the area of each rectangle so I can multiply it by the Parameter, or Max Range in the Fit VOP. This way I can increase the color effect (more white than red) on all rectangle tiles (only working with one right now and will update this thread when it's working on a plethora).

Also, can anyone can figure out a way to make this a white square instead of a circle. I think I'll need a second vector instead of just the centroid used before the distance vop.
