.. but i don't undestand now extract and reimport these animation data..
Extracting animations only works with 3DSmax 2008 and the NWN 2.0.1 import plugin by tazpn.
tazpn's code for animation data isn't complete and it's specifically written for GR2 animation files from NWN.
That it sometimes works for GR2 file from other games is just sheer luck, because the GR2 format defines an enormous lot of animation structs. It's quite a hassle for a programmer to create code for all that, and to correctly identify and read those structs. Then there's also differences in the file format and DLL functions definitions between v2.5.x, v2.6.x etc.
I don't think that a newer version is backward compatible, so a general GR2 reader would have to check the file version.
An updated version of grnreader is my 'grnreader98', debug v1.4.0.3, which I re-uploaded to
http://tatooinebase.star-fleet.org/UPLO ... .debug.rar. This version was explicitly developed for the game Sacred 2, and a tutorial for it can be found here:
