Hello dear strangers,
I’ve managed to bring Nvidia Flex and VXGI under the same roof that is 4.14.3 , my issue is that i have an editor crash while loading one of the test map of Flex (flexsurface).
I would like to figure out what the issue is. If anyone could point me in the right direction or even help me solve this, it would be highly appreciated !

Looks like SetMesh is involved.

The CrashContext.runtime should highlight the issue, haven’t fully dived in yet. If anyone wanna help, you’ll be more than welcome :rolleyes:
