blizribbon help

i have trouble w/ blizribbons

dont get me wrong i can use em pretty well like create them nd stuff, but they dont usually turn out how i want them to

for example i wanted a ribbon that goes pretty fast but leaves a really long trail. when i tried doing this it looked all weird since the colors were almost opaque. how would i choose the colors of ribbon--like i wanted white on the inside and blue on the outer sides of the ribbon--what are the requirements for the "texture" button on the ribbons and how does it uv map it

also for some reason i cant get the ribbons to disappear immediately, it that even possible, if i want a long trail and suddenly they all disappear?

by the way, does anyone kno how to make a cool lookin explosion?
thnx

well, there is no uv mapping on them, their looks goes towards their texture and vertex colouring. Your problem is strange, so i cant help you.
