Gotcha. Thats right. I guess I have a few of those tools from Maya unlimited. If I think of another way, I'll try it. I would like to make something like a wine glass that can move and have the liquid slosh around inside. Obviously a still volume set to transparent can be placed inside the glass and made to look like liquid in a still scene, but in a moving clip it won't slosh around like liquid. Anyone know how to do this? p.s. i am glad you think it looks cool. I am really a newbie and wonder sometimes how bad I suck..........we all get better I guess
