White Halo around Alpha's - Help

[conceptdesign]

I have several 2d photo people with alpha channel I am adding to my scene - When I render these they have a white halo around them - is this a vray thing? The alphas are really good -How can i get rid of this? I would prefer no having to deal with it in post or with different passes - Thanks

Can you post an image, or a small part of it?

Best regards,

Michael,
Try changing the curve in your output setting for the map you have in the opacity slot. Attached is an image of a curve I set after a similar halo problem. You can adjust the amount of halo clamping by moving the middle point.
