I've checked all configurations and i've bean trying several ways to export and inport in different settings and nothing worked. The AO is a setting in direct lighting no in path traising , i'm talking about realistic resaults , not for previews.
What about the UV , can you give more info ? You all ready have my dropbox file all together (obj, png, textures, sketchup file) what is the matter with them? I saw a youtube video of a guy that has a scene of 4 million triangles and octane runs like crazy, (is that a non official video ?) my scene has about 51000 triangles and although i have only one gtx480 , i did not expect so slow renderings (i don't mind about the time but the final pict aren't so good , poor light , lot of noise you've sean some of them) I've send an email to refractive and Terrence told me that i'll find help to the forum, still haven't find an answer that is specific, just controversial opinions.
