i made a destroyable model of the famous German 88 gun. The basis was the model and textures downloaded from www.cadnav.com.
To make it destroyable in the game, the player need to assign a "version" actor to it and set resistance (i.e 6) in HDD Editor.
If anyone is interested, i could send the model and textures via e-mail.
Any feedback will be appreciated!
