Thanks for the advise :)
I was baking the ambiant occlusion into the diffused maps.
The image is that apeals to you is an Architectural concept (SiFi)
I wanted to create a building you might find on the set of Space Odyssey 2001
I drew up some rough sketches and built a model in Sketch Up which i exported to Maya to render AO and shadow, then merged them together using photoshop creating different moods light and dark.
I enjoyed the process and i hope to do more architectural environments.
Mayo for Sam!! :P
