I’m working on a project with destructible structures. I’d like to apply damage to actors that are hit by fractured destructible mesh chunks based on their velocity. I’m attempting to read the impulse from a destructible chunk hitting a collision capsule and am getting 0.0,0.0,0.0.

I’ve tried several workarounds to try to track the impulse of chunks (including reading several of the variables of the hit struct, most of which read the same 0.0,0.0,0.0 value, save for impact normal) to no avail and am at a lost as to what what else I can try. Any help would be appreciated 🙂

Hi ElChipacabra,

Thank you for the report. I was able to reproduce this behavior so I created [JIRA UE-34953](https://issues.unrealengine.com/issue/UE-34953) and our developers will be investigating further. You can follow that link to monitor it’s progress on our online bug tracker.

Unfortunately, I don’t have a workaround for the issue. You would likely need to implement it through code. If you want to look into this, you may want to post a separate report in the C++ section or the forums.

Cheers,

TJ

Understood. Thank you for taking care of that and for getting back to me, TJ.
