100% repeatable crash when selecting a box brush in a blank level and converting to a static mesh.

That’s not good, can I ask for the project logs from ~/Library/Logs/Unreal Engine/?

That will include more details of the failure that we can use to diagnose this problem.

There’s an assert firing that one of the objects isn’t valid so with a bit of luck that won’t be too hard to track down next week.

Apologies that you’ve hit all these issues, but thanks for filing them all so clearly as that really helps. Knowing what is broken makes fixing & improving the Mac version a lot easier.

Being a full-time self-employed Mac developer myself, I completely understand. :slight_smile:

There are a couple more — one of them is driving me insane every 3 minutes or so, but I haven’t figured out how to replicate it consistently and it doesn’t cause a crash so I have no log to send along…

Having the same problem here! Hopefully will be a fix soon- for the time being you can create the static meshes in 4.3, and re import!

This appears to be fixed in 4.4.1.
