Higher values yield smoother results but render more slowly, while lower values render faster but look grainier. Diffuse needs slightly more artwork - I like to start by painting a basic tiling texture over the uv islands (in this case, mostly galvanized metal), and then adding the ambient occlusion bake over the top with a "hard light" filter. Values in the range 16 to 64 cover most situations. So the Ambient Occlusion (from now on I’ll simply call AO) throws shadows Environmental linked to the proximity of objects and – above all – is not linked in any way to the light present in the scene. 8 bytes per point on a 32 bits OS - with a maximum depth of 10 - and 12 bytes on a 64 bits OS - with a maximum depth of 21!). , 2008) with models then opened in CloudCompare (version 2.
