Im happy, now i have such an effect in my weapon script. Not perfect, but pretty cool, 4 my taste. Invested some work into smoke - sprites + alpha channels, combined them with player's movement vectors. Then i "rayp-ed" an Shade-C(evo[beta]) - effect, normally used 4 steam, softfog etc.
Code:
sc_ent_softFog (ent, vector, vector, vector, var); // see shade-c(evo) script 4 more infos
"ent.alpha" keeps working with this effect applyed, nice ^^

In some weeks ( maybe month ) i planned a small videoupload, if someone interested, he / she can watch it then to see the result / effect in motion.

Maybe one of the shader-gurus is bored ... would be a nice contribution ^^

Peace
