Hey Guys,
We found a bug where some Union failures wipe the Physics data of a Union. Trying to figure out exactly where and why this happens and it doesn’t happen 100% of the time either. It’s not catastrophic because you can separate the “lost” part and then re-union to get the Data back, but still be careful.
You can be on the look out for this behavior by going to File->Settings->Physics->ShowDecompositionGeometry
When you are in this mode, the part that loses it’s data simply becomes invisible (but you can still select it). I’ll update here once I know whats going on an an update on the fix.
So far it doesn’t seem to be super far reaching, but I figure I’d let you guys know ASAP just in case!
