cloud tutorials

Hello,

I'm here to ask if anyone has a really good tutorial on how to make really awesome, stormy looking, puffy clouds in 3dmax9? If anyone does, I'd greatly appreciate any help on how to create these for a movie I'm making. I also need to know exactly what plug-ins I'll need and where to get them if I need any.

I found a few and tried to follow the directions, but always ran into a snag. I get to a point where they ask to add an item and I do not have them. I've tried to download a few but got viruses and had to delete them.

I need a complete step by step tutorial on how to create these clouds and add some animation to them to make them look as though they are moving in all directions. I do have a picture that shows what I'm looking to create but don't see any place here to attach it.

I'd apprciate any and all help in this project.


Thanks
