I saw on the Renderosity home page about them asking for renders to use in advertising etc.

One question I did not follow is the 300 PPI - pixiels per square inch. Thats something I am more familiar with in the definition of a monitor. - I figure it means the same thing for a render - but how do you know if it meets that criteria or how do you set the Rendering engine to meet that? - which is probably the better question.

Thanks
