I just added Aurra Sing to my map and have the problem that she doesn´t work the way she should.

If i´m right she has only one attack anim. Not enough she will stop using it and everything else like mine laying after a couple of times. The only thing she can then i just running around.

I get following errors:

Message Severity: 3
C:\Battlefront2\main\Battlefront2\Source\SoldierAnimatorClass.cpp(1881)
Can't find soldier animation obiwan_sabre_stand_dashattackend(_upper)

Message Severity: 3
C:\Battlefront2\main\Battlefront2\Source\SoldierAnimatorClass.cpp(1881)
Can't find soldier animation obiwan_sabre_jumpattack_recover(_upper)

What have i done before:
I copied the odf and msh files to my sides IMP folder and the obiwan.anim zabin and zafbin files to the sides imp munged folder.

Next i replaced here first weapon in the odf file (will switch back to the original weapon once i found the needed files):

WEAPONSECTION = 1
//WeaponName = "rep_weap_lightsaber_obiwan"
WeaponName = "imp_weap_lightsaber"

Last i added aurasing to the imp sides in the LUA file.
No other changes.

What is missing or what did i wrong?

Your error log is telling you that a couple of animations are indeed missing from your animset.
