Sprite image not displaying properly

[clumsy_culhane]

Hi guys, for some reason this is happening :


There shouldnt be a black border around the explosion.

Ive tried editing the alpha channel of the .tga with Photoshop, to no avail.

Any help would be very appreciated.

There is no alpha channel. Either use a particle class that uses additiive blending instead or add an alpha channel.
