two-sided landscape usually works. However, have you guys tried out the Voxel 1.2 free plug-in from Epic? for some reason I don’t get a hit on the Voxel terrain… I tried multiple different settings and at first, I got it to work then it died! and haven’t been able to get it to do it again. I spawned several rocks both above and below the voxel terrain, but they won’t move to it. (Procedural Placement isn’t available in the Voxel free version).
