Worldposition pass without AA

[Siahpoosh]

Yes,

Render Setup/Corona Settings/Actions/Render only elements (without AA)

Yes, for now there is no workaround for that. You'll have to render twice. However, when you're rendering utility elements, A) you don't need AA, so 1 pass is sufficient, and B) you don't need GI, so the pass will render in seconds.

right , but its not fast enough in large scenes.

How do you figure? If you can't afford the extra render time from rendering a single pass without AA and without path tracing, perhaps you should be using a faster engine with more bias, like V-Ray with irradiance caching or whatever?
