That terrain looks very very cool. how did u do it...displacement obviously. but was it just procedurals?

The lava still doesnt look quite right IMHO....you could try using a top/bottom material...that could work....maybe

Yeah the lava sucks :P
The lava rock on the other hand I am very happy with, simple really, a dark grey mat (solid color) with just a bit of reflection and the displacement

[DaForce]

what did you use for the displacement?

Displacement map is a photo of a lava flow
