So I just remembered that I've never posted any of the work that I did at BMW on here (the non-secret stuff that is) so here goes...
These shots are of an environment I created when there when work was quiet. It started out as texturing practice, where I wanted to really get the most out of tileable textures. I started with the road an built outwards, and as I progressed people started to like it and suggested that I turned it into a realtime environment in which to view cars.
The setting is a mountain race track, featuring the iconic tunnels found all over the Alps and similar mountain ranges.
The rocks are made out of a modular system, where a tiling texture is placed over one rock formation. This rock is then duplicated and intersected to make a wall featuring interesting grooves and ridges. I picked this up from Crysis.
This scene is rendered in real time, with RTT Deltagen, one of the programs I did the most work in at BMW. I also rendered a HDRI from it for reflections and Image Based Lighting.
