I'm working on a mesh at the moment and just trying to figure out which way to go with animating it and collision. Basically they are large contra-rotating gears and I need to have the teeth with collision so they have to be Mopp. Can anyone remember seeing any complex animated nifs with multi Mopp collision animated?

I have no clue what a Mopp is, but I always use http://www.nexusmods.com/skyrim/mods/34399/?, which has large animated gears... not sure if that's helpful or not
