muzzle flash

how can i make a muzzle flash.
i know the animation and the plane but how do i get alpha to tranperant.
because the black is stilo viseble.
is there a video on the internet?

try setting the texture to add in the uv texture tab (2.49)

i am using blender 2.5

Are you using GLSL? because there is a different way for GLSL and for multitexture.

try this (http://www.blenderguru.com/how-to-create-a-muzzle-flash/comment-page-2/#comments) probably not exactly what you are looking for, but is good for realistic muzzle flashes

i think i am using multitexture
and 52 Studios: good vid but to hard for me
