Thanks for the quick reply. For now I am happy that it is introduced in 4.26. Strange that is hasn’t been there before. Wonder how other “auto landscapes” have implemented this. I think have a workarround tough for other UE4 versions if you are interested. Simply output the masks on separate layers and apply a physical material on these layers.
Great to see some activity on the anwserhub, haven’t been here for years after UE4 went free.
