Any idea how to extract and edit AO weapon models?

I am interested in extracting the 3d meshes and textures of the AO weapons. I have googled and searched, but no luck. Could someone point me in the right direction please?

The models of AO are stored as NetImmerse files.

You can view them with [Only registered and activated users can see links. Click Here To Register...].

But to see all texture you have to "convert" the texture dds files first, since ndoors/nexon are using "custom" headers. ([Only registered and activated users can see links. Click Here To Register...])

Ok, thanks, I have NifTools, what is the filename extension that I am looking for to extract?

*.nif files are containing the "model description"
