I think everyone's sorta hinted in various threads at the need for a solid tutorial to explain how to port stuff from BC or SFCIII to Legacy. If a gracious someone feels up to the job, I'm sure the effort and tutorial would make all us rookies feel a lot more comfortable with Milkshape. :)
There is a tutorial to Milkshape3d on Armada2files.com All you have to do is importing NIF file and then just follow the tutorial http://armada2.filefront.com/file/Milkshape_3D_SOD_Tutorial;24066
If you don't understand "Parents nodes and other stuff like that" , download "DoW Galor and Keldon" from Armada2Files. Those two are stock .sod files and You can open them in Milkshape3d to see what's inside.
