You mean like an animation? With a script like:
:state=0,shotdamage=25:setframe=1,state=1
:state=1:incframe=1
:state=1,frameatend=1:state=2
That way if the object is shot at then it plays an animation, useful for making a chair break or something. Of course, you could also add some randomization (3 diffrent animations for breaking):
:state=0,shotdamage=25:state=1
:state=1,random=2:setframe=1,state=2
:state=1,random=2:setframe=2,state=3
:state=1:setframe=3,state=4
:state=2:incframe=1
:state=2,frameatend=1:state=20
:state=3:incframe=2
:state=3,frameatend=2:state=20
:state=4:incframe=3
:state=4,frameatend=3:state=20
If you make future model packs (or want to expirement with the idea) feel free to use the script

Haven't tested it though
