I've had this muzzleflash desire for a long time, and after a couple of hours of tweaking, I managed to come up with some cool stuff.
If you look closely, you may notice some random sparks. I've watched some real weapons' muzzleflash videos, and I've documented myself regarding the speed and colour and I can shamelessly say, it looks perfect.
I will have a video pretty soon, I need to get a proper gun first.
/me goes off wondering where's that 3D modeler...
