Hello.  
I have a question regarding Chaos physics engine. Is it possible to make Geometry Collections affect Navigation Mesh? I made some tests and even when I turned dynamic mesh generation, Geometry Collection object (before and after destruction) did not affect NavMesh and my AI couldn’t pass it.  
Is this functionality implemented? I’m using UE 4.25.3 compiled from source to use Chaos.

Thank you very much for help.
