blurry alpha channel edges
I am trying to render some foreground stuff in a separate pass so I can later composite it into the background, but the edges in the alpha channel aren't sharp enough, resulting in a blurry halo around the foreground objects. Does anyone know how to make the edges of the matte sharper?

Thanks for the tips! The image i'm trying to get is of an island with some vegetation on it. I did the vegetation with Paint FX and I was just simply unable to get a good alpha of just the paint FX and their shadows, so what I did was I rendered a pass with both the island and the paint FX (top pic):

The problem I am having now is getting a good ocean pass. The biggest problem is getting rid of the Sky portion of the Water/Sky envFog Material. Even if I set it to just Water, there still seems to be some Sky fog showing up. The pic you see here of the alpha channel had the levels adjusted in photoshop to more clearly show the lingering fog. The last pic I tried rendering against a white background, but that didn't work either. I have no idea where to go from here, any help would be greatly appreciated. Thanks!
