Ambient Occlusion 2

Once I have worked out how to make ambient occlusion on the simple primitives i tried to make it on my actual model. And what a surprice! mental ray doesn like my textures, it simple gives me and error mesagge saying this jpg. files are not recognizable. I have found a way around it by dublicating the scene and deleting all the materials and history of the objects (because of that i won't be able to work out if ambient occlusion works for bump maps, there are plenty of them on the crown body) Only then ambient occlusion worked well.

ambient occlusion

combination of both

makes a big difference to ornament elements.
