Todays work done! It's the Ko Tapu rock formation located in Thailand also known as the "James Bond Island" where it has been featured in the movie "The man with the golden colt".
The rock is a dense mesh that I built from a simple polygon shape displaced with various Bercon Noise maps applied at different subdivision levels in conjunction with a lot of volume select modifiers. The texture was sourced from photgraphs and patched together. Vegetation is of cours GrowFX.
