Here's kind of a Wip/process.. not sure really..so if you are interested.. Basically blocked out the terrain with Tools -> Terrain.. (default 16 x 16 patch) in the UDK editor.. And then painted it with textures using the terrain painter (Shift + 3).. =)
The basic idea I have in mind is inspired by an Asian Naga temple (Angkor Wat and Neak Pean).. Mmm.. I quite like the idea of it.. =) There's some ref at the end so you can see what I like =)
Also made my own skydome and played around with a post process volume (there's a volume brush on the right hand side of the editor if you want to play around with the depth of field using a process volume).. =) Mmm.. Also put in a dominant light source to make the ambient lighting and then set the reflected light in the world properties.
Next, I'm going to try and refine the terrain a bit and then try work in my own building materials and textures. I may scrap this test altogether though, see how it goes =) See you guys =)
