Unity Probuilder prefab cause lag/freeze/corrupts

Question

Here’s my experience:

• I created some normal objects in Probuilder, which basically are just merging Spheres and Cylinders together, nothing else, and everything was fine.
• Next thing I did was make all of those objects become prefabs.
• First one was normal, the second took a few seconds, a bit laggy you could say, and the third one just took…it never finished.

I made a new, blank project and ran it. Everything’s fine, copy all of the things in the bugged project and the editor just fell in a loop of loading and it also never finished.

So I checked the “clone” project’s file and deleted the prefabs that I made from Probuilder, because that was the last thing I did before all of these things happened, and it works! Everything turned back to normal and never froze again, unless I tried to make those prefabs again.

So why did that happen?

I never know. I have read some close to similar threads such as Unity became slow or frozen loading screen or something…Anyway, I hope this will help anyone who has the same problem as mine.

Can you please report a bug and attach your prefabs and scenes? You can find more info about bug reporting here https://unity.com/releases/editor/qa/bug-reporting

Answer 1

We just got bitten by the same issue and couldn’t work out what was going on. Unity would hang for 1-2 minutes when ever we loaded the game scene or made a small edit.

When we removed the prefab that contained a ProBuilder mesh (and expanded it into the scene not as a prefab) everything worked smoothly with no hangs.

Thanks for reporting this @Adkinson as we thought we were going mad.
