When working with TTT as the parent addon. You have access to addition features in ModelDoc for your models. This page contains all customs features and what they do

A node to add to a physics prop that will change how it behaves. Below is a proper setup of the node and descriptions for the properties of the node.

Determines how much damage a prop will deal with physics (propkilling power). Higher number will deal more damage, 1 is default.

Set to 0 if you do not want the prop to deal damage

Determines how much force breakpieces get when broken. This is determined by the direction of the damage from where it was hit (ie hitting with a crowbar will send breakpieces flying away opposite from where hit).

Set to 0 if you do not want this

Determines how much breakpieces will explode from the center (ie an explosive barrel exploding out from the center). Uses the origin of the model as the center of the burst.

Set to 0 if you do not want this
