Roblox Unions - Bug Report

Important Info:

So i’ve been trying to make a showcase… and im making an inner wall design… I had no problems when making half of it on 1/26/2023. However when I went to make the rest today 1/28/2023 the unions started glitching… 1st it would give error -11 like shown in the picture below…


Also Important Info:

I’ve spent hours trying to fix this… I tried remaking the entire wall with new parts… thinking maybe the parts themself got corrupted or something. That didn’t work… So I tried doing smaller groups of unions since it was 94 parts… that just gave a different glitch… After a while it “worked” but then it caused the union to not function properly… For example if you tried to drag a part onto it then it acted as if it was inverted. I forgot to take a screenshot of this glitch but I couldn’t recreate it either so it probs doesnt matter.

Extra Info: (Isn’t important)
Anyway… Just wanted to report this because I have games to make and deadlines to make and this isnt letting me do what I’m supposed to do… I’ve literally stayed up to 6 am trying to get ahead because I was behind just to encounter this…

This is possibly caused by the Beta Feature CSG Engine 3. Disable it and try unioning those parts again.

That worked thanks… Idk why I didn’t think of checking beta features… lol

CSG is not recommended for use. In the future, do not use unions. Unions have an 80% consistency rate for mobile users, meaning that 20% of the time the union will not load at all. If this wall is significant to the game, I recommend using parts instead.

its just a showcase… its not like im making an actual game… i would just use blender for a game.

Hi @HuskeeTheDev,

We’re collecting examples where CSG v3 is producing those kinds of errors. If you still have an rbxm or rbxl file that has a -11 or other CSG error, we’d love to take a look and fix it. Thanks :slight_smile:

I put it in a new place and it still seemed glitch with CSG v3… It’s not getting error 11, but its also not letting you undo the union either so I hope this still helps.

Also just a completely different topic question… Do you know anything about the roblox questionnaire updating on the dashboard but not on the game page itself?

Thanks @HuskeeTheDev, we were able to reproduce an error using that file, much appreciated. We’ll take a look into what’s causing the issue.

About the roblox questionnaire, sorry, that’s not something I’m familiar with
