Removing hundreds of gradients at once in a low poly image
So I used a web tool to make one of those low poly mesh images that look like 3d modeling. It's not this image, but the same style. There are hundred of triangles that make up this image, and most of them are filled with unique gradients. I would like to "flatten" these gradients to the average value of each triangle (so I would keep some of the 3d look but I could alter for screen-printing). Any ideas? I know I can click on each triangle individually. Should I move to photoshop and posterize?
