How do I make a destructible mesh take an impulse?

I’m using the First Person Blueprint example that comes with UE4 to learn how to use Blueprints currently and I’ve been messing with adding a destructible mesh to the mix. The problem is, is that the destructible mesh won’t take any impulse, or move at all… Is there a different way to do this that I’m not aware of? Is there maybe another way to go about it?

anyone found a solution to give an impulse to a destructible mesh?

My destructible mesh is just breaking and fall on ground without any impulse cause i dont see on what object i have to give the impulse :o

Hi Skeleton60:

Do you have “start awake” unchecked for your destructible mesh. This will keep it from destroying immediately and waiting for contact from your projectile.

Let me know how this goes and if you need help feel free to ask! :slight_smile:


Hi Skeleton60,

We’ve not heard back from you in a few days. I’m going to mark this as resolved for the time being. If you’re still having the issue feel free to post here to open the thread back up.

Thank you!


Hi guys, i having the same problem … How do I make a destructible mesh take an impulse?


Here is the setup I use in my Level BP for testing a DM taking an impulse. You can then apply this however you need, but this will at least get you to the testing and then you will need to implement it with your needs.

For your DM in the details panel once in your level:
Generate Hit events marked as True.

Then setup up the following: I have a trigger box in my scene that is triggering the simulate physics and apply the impulse when entered.

In this one I’m using an Add Impulse. It’s a simple bump to the mesh.

This other one I prefer to use the Apply Radius Damage because I can control the radius, damage applied, and the impulse strength all through variables that I can make editable.
