Position Buffer or Reconstruct from depth?

Graphics Shaders & Materials

Is it possible to output a position buffer or do I have to reconstruct the position from the depth buffer?

Unity 3 RC1 btw

Thanks

Reconstruction position from depth is both easier faster I think. You can check how deferred lighting light shader does it (Internal-PrePassLighting.shader in builtin shaders)

Ok thanks again Aras.
