Alpha mapping foliage white border

AnArtAccount

Hello,

I have a small question: I wanted to make a render of a plant I made in 3DSmax in Toolbag. The transparency works fine in Unity3D but when I want to render it in Toolbag, it get's this white border as shown in the image below. When I zoom in really close, the border is gone. But the more I zoom out. How bigger the border gets.

Does anyone know how to fix this?

Thanks

Generally this happens when your image background is white. If you change the BG to a neutral green closer to the color of your leaves that should sort it out.
