How to change the model of the player's body and viewhands? (I need a model of the Russian soldier mission Seelow)
Like this but in zombie mod

Fixed image.

First you need to find both the player- and viewmodel via the asset-viewer (which is located in root/bin, has a simple search-function).
Then for the viewhands you have to got to root/raw/maps and copy the _loadout.gsc to your modfolder (if you used the UGX-scriptplacer it would be root/mods/yourmapname/maps).
Then open it up and search for (normally by pressing shift+F):

else if( GetDvar( "zombiemode" )

a few lines underneath you should see this line:

set_player_viewmodel( "viewmodel_usa_marine_arms");

(it's necessary to search for the other line first, as the second one appears multiple times.)

Then you only have to replace viewmodel_usa_marine_arms (leave the ""!) with the viewmodel you want.
(would be more complicated if you used one from another game.)

I sadly don't know how to change the player model though.

Map's csv:

include,common_player_rus
xmodel,viewmodel_rus_guard_player
xmodel,viewmodel_rus_guard_arms

_loadout:

set_player_viewmodel( "viewmodel_rus_guard_arms");
set_player_interactive_hands( "viewmodel_rus_guard_player");
level.campaign = "russian";

Thanks all!)) It's work!
