Nubie question on animation

Does anyone know where i can find a good tutorial on how to do lighting effects? Also is there a tutorial that anyone knows of that can show you how to move bubles throught a transparent tube?

I think that I made a post on bubbles a while back in this forum… I’ll see if I can find the post

Lighting isn’t easy… there are a number of different lighting effects.

Did you do the “Ray Of Light, revisited” tutorial on Kirupa.com?
