CSG is super super buggy what changed recently?
Unioning them one at a time works
Is there a way to use unions without 30-50% of them turning invisible?
I’m still a newb but to me it seems like any model with more than a few unions creates fatal issues for roblox.
You can try enabling “DisableCSGv2” in Studio settings.
CSGv1 was far more stable and didn’t corrupt unions as often.

Thank you. I tried that but it did not seem to help. I’m assuming I just change the setting and restart studio, is that correct or am I missing a step?
It’s just an older CSG system.
It will not affect unions done in CSGv2, nor will you be able to edit them while having CSGv1 enabled (from what I know).
So it’s not a setting that you switch and everything gets fixed. You have to use it, make unions with CSGv1 system, and you should see the difference.

Uh, I tried “unioning” two unions together to make a grid and this happened:
However, when I separate the union, the unions are the unions from before (I mean they’re completely fine).
You need to add a repro file for this so that they can investigate. A picture alone doesn’t help because they don’t have your setup parts.
Studio crashed after that so I can’t get a repro file, it was a brand new file too…
Right, here’s mine. Things just turned invisible after union, and then they disappear after being separated. I’m no expert, so I’m not sure of the specific cause. And I can’t remember how it looks like so… I’d really like to solve this.

That’s a known issue that isn’t really being solved. Another reason I don’t like to always use unions. Basically your union was corrupt. You can see the outline, but if you try to alter the shape of it/union it, then it deletes itself. This has happened to me on MULTIPLE occasions, one time literally destroying my whole game which I spend about 4 months on and was almost complete.

I guess this falls under CSGs that create invisible/extra parts.
Basically, I was in team create with my development team working on a game. We found that during the team create, if you negate something, no one else can see the item you negated. Others can undo the union ans then see everything, and you can move it, etc. but you cant see it when testing it or viewing it in studio.

Steps to replicate:
Create a Group Team Creat with 6+ people(this might work with under 6 players but I’m just going off of how it happened to me) > Get some parts, and have some negated parts > Union them
It’s getting really annoying not being able to negate items. I hope this gets fixed soon.
I’m pretty sure what’s happening with your example is the union is having too many tris for one instance, so it’s reducing the try count by basically decimating it. Super annoying, it happens to me all the time.
This falls under CSGs that can’t seperate.
When I try to union the union to the 2 parts, it returns with error code -25. Trying to separate the union results in the union just getting deleted, and nothing happening after that.

EDIT:
Bug has been fixed, just had to reopen studio.

Hey, so if this still happening have you tried only saving to file and not publishing and just bringing the stuff youve made from the files to the published place?
Should be noted that recently, CSG objects are randomly disappearing after creation. This can occur a day, or several weeks after the Union’s original creation date. I am not sure if there’s a repro for this, because it’s extremely random.

My unions for a door has been acting very weird. So i have the same door union in 2 different places (place 1 and 2). In place 1, the union is fine, everything works. But in place 2, if i were to insert the unions in. It looks fine, but when i test/play, some of the unions are gone. And if i were to close and reopen studio. the union is just disappears in place 2 (forever). And if i play online. it’s just gone. Help would be appreciated. Thanks!
(Before playing/running/testing in place 2) - In Studio
(After playing/running/testing in place 2) or (After openening studio again in place 2) - In Studio and online
place 1 doesn’t get affected by the issue. But place 2 does. Help would be appreciated. Thanks!

Mega-topics about a single feature are not that useful as they do not stimulate users enough to provide all the necessary details, so closing this in favor of small, individual bug reports about specific issues.
Please file separate topics in the Studio Bugs category when you encounter issues with CSG/unions.
