I just finished my ambient occlusion map which will be used to add shadow detail to my diffuse map. It proved very awkward to create. I created it by splitting the model into 4 parts and AO'ing them. I had some issues with this too. I had to get rid of any overlayed UV's until there was only one set left there. I also ended up with many small artifacts which I had to remove. I also ended up hand painting a fair bit of it as I felt some of it should have more/less pronounced shadow. Overall I think it will be helpful to my diffuse. I also have it setup so that I can edit it further once I start adding more details to the texture (in case it doesn't look right). Next I plan to either create the diffuse map or the normal map.
