I'm talking wind and moving leaves and branches and things. Did they provide any sort of tool that could be used for that purpose or is there some other way to do it?

Trees are NIF's this time, so I bet it's possible to get them animated with the same system. It might mean a lot of hand editing in NifSkope though, I'm not sure. MERP's modelers are creating trees, but they're still mostly busy with the look of the model itself and not yet the tree animations.

Bump, would like to know if anyone else has info on this.
