Better Alpha Pass

[Daniel Doerksen]

For compositing mainly if i do a render with trees and theres sky in the background.then take it into Photoshop and place mountains in you get a halo effect around the trees. whats the best method for getting around this? Is there a way up creating a better quality alpha map.

use a black background instead of the sky. If you need to keep the environment for reflections/lighting use the vray environment overrides.
