Like one of the people in the following threads i have been following the guide http://forums.totalwar.org/vb/showth...its-to-Rome-BI to try and get a m2tw model into rtw.

So far i have imported the model into 3dsmax, then i come to the part in the guide "they come with several models in 1, so to speak, pick a layer and delete the rest" does that mean i have to do something in the first of the attached screenshots. Also it says " import hide it and import a unit from RTW using the .cas importer, use that skeleton/bone", is this step neccessary? I expect the model already has a skeleton doesnt it? I'm new at this, so any help is welcome.
