Hey ,
Thank you for this awesome thread and the work you’ve been sharing.
I’ve currently run in to a snag and I’m wondering if anybody else is having the same problem. If I create a blueprint to run line traces agaisnt the dynamic meshes I’ll eventually get the following crash:

I’ve confirmed that in other projects without the dynamic mesh instances that I cannot reproduce the crash. I’ve attempted to debug the issue by running the engine from VS with debugging on, however instead of a break it simply freezes and crashes to desktop. I’d be grateful if someone else who’s implemented the dynamic meshes would try and run a few line traces to see if they see the same thing. Otherwise it might be something on my side unrelated to the dynamic meshes. Here is my blueprint for reference:
The trace will fire and show up on the meshes a few times but eventually crash. Sometimes it crashes early other times I have to spam it about 20-30 times to get it to crash.
Thanks.
