No overlays. Just layers and layers of micro-displacement and various other shaders like fake stones are used. I tried displacement but Vue slows down a lot and at times crashes with using this feature. Getting into the function editor is easy enough. I was just wondering if anyone ever tried at such small details of barrens terrains close up like this.

To me it seems to take longer to render using displacement although i may be wrong about this. Had anyone else experienced a slow down using displacement?
