Polycoutin generals/zh should be below 1000 for units and for buildings you might get up til 1200-1300!
Donno what you wanna now about animations?!
For tutorials on how to use gmax/renx look at
www.discreet.com.
Fot tuts especially generals/zh related issues with Renx/gmax, eg. settings you have to use, when exporting your models, try the tutorials you can find here in the download section or search for Proclone's tutorials (google!)
Btw: don't get that wrong, but your grammar is horrible, makes it very hard to understand what you wanna know, try to be more exact in your future posts
