HEADS UP: Solid Model Physics bug in the wild - Physics Data disappears when Union Fails (rare)

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!

Does this include only UnionOperations or does it also include parts? I’ve seen parts snap to the origin of the workspace after a failed union. Maybe that’s a different bug.

That’s a different bug and we have a fix that we will try to get out in a Studio patch asap.

This should have been resolved in last night’s patch.
