[Bug] ProBuilder meshes not editable

I have multiple ProBuilder objects in my project. Now I noticed that some of them are broken. I have three behaviours:

• The object works as expected (about 50 % of objects)
• The object is not editable. No error present. If I try to export it or make it into a prefab, all the geometry disappears and the object has size 0,0,0 and complaints about missing normals and UVs. If I reload the scene the object re-appears.
• The same as above, but the object disappears as soon as I select the object in inspector.

Unity 2018.3.1f1 with ProBuilder 4.0.2 .

EDIT: Edited the ProBuilder ver. no.

 

Hi,

Sorry for the confusion. I meant 4.0.2 . I observed it at 3.0.8 before and tried update to see if it would resolve the issue. Somehow the two numbers mixed in my brain.

I can't unfortunately say at which point exactly it stopped working, since I was not touching those for a while. I can go back to a version where the meshes still worked but I would have very hard time trying to track exactly where it happened.

Is there another information I could provide? I can try to make a project with the broken file only if that helps (will need a bit of time)?

 

Ok, I managed to make a example case project (the repo has 40GB normally that's why it's difficult to seek versions explicitly).

Case 1120730

If you figure out a way how to fix them in the current version I'd be super happy, it would be a pain to have import-export all the objects from older version of the project.

 

No problem, thanks for looking into that.

For the repair, the behaviour is the same:
- If I do Convert to ProBuilder 4.0.2 it launches the utility with the message "ProBuilder is up to date".
- If I click any other option in the Repair tab (Rebuild, Remove triangles, etc..) the objects dissapear (same behaviour as above).

 

To make the bug report I created a new project, copy&pasted a single scene from my project and removed anything else but the ProBuilder objects.

I tried also the approach with removing the Pro Builder Mesh script and putting it back, but the ProBuilderize button does not do anything on the object afterwards (no script created, no error written to console either).

 

So when you clicked "ProBuilderize", there were zero PB scripts on the object, right?

Yes - before I remove it, the button is grayed out. But once I remove the script the geometry disappears:

Does it work on a standard Unity cube?

Yes, no issue there.

 

@gabrielw_unity This sounds like the same issue I mentioned here. I tested a standard Unity cube and can confirm it does work without issue there. Any other mesh seems incompatible since 4.0.3.

 

Update on the bug report: "We have been able to reproduce this bug and have sent it for resolution with our developers."

 

I'm still having this issue with the most current version. After using the merge function, I lose the ability to select edges, faces or vertices.
