Destructible How to #1: Effectively using “Import FBX Chunks” for Destructible Meshes
In this setup I’ll be using a parking meter as an example.

This such a great feature that really gets overlooked when thinking about destruction meshes. Often you think destruction and things have to fly apart or break free from other pieces. However, this is not always the case. If you’ve ever played any GTA game you’ve seen this method used very often, especially in the city.
The goal here is when enough damage is taken by our destruction mesh it will destroy (swap the meshes) and trigger a particle system for added effect.
Here are the settings that were used in the DM:
Enable Impact Damage: True
Impact damage: 1.0
Default Impact Damage Depth: 1
World Support: True
Support Depth: 1
Impact Velocity Threshold: 750
By setting the impact velocity threshold higher or lower you can determine how fast something needs to be traveling to cause damage. Anything below that will not affect the DM.
Also, note that this is one particular setup and can be used in many various ways.
