It’s a bit unclear for me, where in this case we assign color to group? Could you please prodive some pictures?
In my case every begin play event I want each group of Sphere BPs get their own random color. On the first run all spheres on the right become lime green, spheres on the left - dark blue. On the second run - left ones become pink, right ones - black, on third - yellow and brown, etc. And there will be a lot of different groups…
