Using the DDM...

[Xion(810)]

Can I get a quick rundown on what stuff does for the DMM? (DMM is Dynamic Movement Modifier...right)

[UnConeD]

It's dynamic distance modifier. It allows you to express a formula which changes the 'd' polar coordinate depending on a formula. Sort of a more limited version of the dynamic movement, but it works differently.

...is there any kind of demo or tutorial for those two items? I think that if I add those (or one of them) to my presets they may get better...

[Jaheckelsafar]

There's a few. A pretty detalied one went on between nic01 and cmountford. I think its "Sneak peek at AVS pack" in the presets section. Do a search, look at the Unconed's FAQ. You'll find something.

Dynamic Distance Modifier is like such Dynamic Movement, however, you can use only d. (D meaning distance).
