A lava terrain processed in TE-Filters v1.14 and left grey. A bit of transparency, specularity and anisotropy. The camera looks through the GWL (gigantic wide-angle fisheye lens) onto the terrain. The ring is the horizon. The main light is from the Icefire HDRI (that comes with Bryce 7.1, but specular convolved) and the sun brightens up dark parts.
