I am having an inconsistency between outcomes using the node Geometry>Random per Island

It is the same node setup behaving differently between 2.83 and 2.9

2.83: I will get the colors assigned to the color ramp distributed within the meshes that have that material. The limitation is the “island” meaning that closed meshes will have one color assigned.

2.9: Every different face of my mesh will get a different color from the color ramp. This is not what I need since I am trying to assign random colors to multiple assets, but each asset in itself can not have a different color per face…it looks really funky

Have you experimented this?


not sure if answering 9 months later is going to be helpful but I came across a similar problem yesterday. In my experience Random per Island works fine until you use autosmooth (Botom Row of the picture) thats when it gets funky, it also changes if you are using hard normals (first column of the picture) or smooth normals (second column).
