Opacity Map (White Edges)

Hey guys, I was wondering have any of you had a run in when dealing with opacity maps in Unity, where the edge of the plane had a white edge on it. I have run into this many times, and was wanted ot know, if I was doing anything wrong, because the opacity map looked fine in Max.

Thanks

This could be from the wrapping mode of the texture. If you select the texture used for the map in the project view, you can change the Wrap Mode from Repeat to Clamp.

If that doesn’t help, a screenshot of the issue would be helpful in figuring out what it is.
