How to make decals fade away?

[il Duce Primo]

How would you make decals fade away? I'm making footprints and I want to make the decal fade so it doesn't just rapidly vanish.

Look at the effects for the plasma rifle bolt projectile and see if you can apply the same concept of the fading glow to footprints; not sure if you can, though.

In the decal tag, go down to Animation.

Loop frame is 0, speed is 1. Lifetime is whatever amount of seconds you want it to last (keep both numbers the same to be constant). Decay time is how many seconds it takes to basically die/start to die. The rifle is around 180 seconds in lifetime and 20 seconds in decay time. Keep yours shorter. I'd say 60 seconds in lifetime and 20 seconds in decay time to be more realistic.
