Ambient Occlusion Baked

I've been baking a number of Ambient Occlusion maps recently onto my models. I started with the bedrooom at 512 samples and it took roughly 5 hours to complete. I'm having to do this over night!
Its a fairly simply process of using Mental Rays ambient occlusion shader, then turning up the samples to 512 and using the baking feature. Then once complete (ensure to have your project set up correctly) the maps will be avaliable in the renderData folder within your project. Then simply take the map and the texture file into Photoshop and do a multiply blend mode. There you have it baked maps.
Some examples below
