I've been trying to modify with the sword trail from the UDK GDC level. I'm trying to have the trail be a bright JRPG-like slash. An example I guess would be this image:
However, I'm not sure I'm approaching this correctly because my trail doesnt look smooth at all. Not only that, the color doesn't even get close to the glow. I can see the rough edges of the emitter spawns as the sword moves in air.
Any idea how to make a glowy slash like the one in the image?
