I tried to duplicate your issue using 2 different textures and 2 kinds of light colours and intensities but don't get the white outline effect you're suggesting.

Alright i found out what the white outline was its the background that i original used wen i made it transparant. i changed the color to green then selected it. new layer in gimp i save it as tga wen i import it i get a green line around. i have no idea how to remove it.

if you need a picture to show what i mean let me know i will make one.
and thank you for taking your time to help me :D
