It can be done.
But it involves several things.
1st
Animations need to be created.
This takes someone that knows what they are doing just to get the animations ready for import.
Then the actual import of those animations into a working dat.
2nd
Every unit that you want them on needs nodes added to place the animations.
Then the eqp files need corrected to allow them to appear.
Your talking about over 200 ships for GWX 2.1
