Destructible pieces mass/gravity not respecting Mass Scale?

Development World Creation
1

Unreal 4.8.2, we’re using the Destructible component to explode a wall, only the chunks fall at a pretty slow rate. We’ve tried adjusting the Mass Scale, but it doesn’t seem to have any affect. I found an older thread (Destructable Mesh blowning apart too hard - World Creation - Epic Developer Community Forums) which mentions a bug (UE-5642). Our quick look at the source code doesn’t show anything being set by the Mass Scale.

Is this still an open issue?

Hi SignalZak,

This issue is still open and is currently backlogged at the moment due to other priorities.

As a workaround you can try using a Physical Material assigned to the materials used for the Destructible. In the Physical Material you will want to adjust the Density value to be higher.
