Depthmap for alpha mapped leaves?

["Morten Bartholdy" <xsi(at)colorshopvfx.dk>]

I am doing a jungle shot where many of the plants have alpha sprite mapped leaves. Now I need a depth map, and using etither BA Raylength or scalar state works almost fine with sprites - only problem is a thin line of brighter pixels on the aliased edges of the alpha  - do you guys have any ideas on how I get rid of those?
