CSG Union Returning with Error -11:

Bug Reports Studio Bugs
#1

Reproduction Steps

  1. Go to Roblox Studio, select/create your baseplate, and insert parts;
  2. As having two parts, union them and duplicate further (for my case, 13 was the amount I did);
  3. Duplicate the 13 union parts four times and move in a bit far distance;
  4. Go to MODEL, and select Union.

Expected Behavior

I expected that it could union all of the selected parts to make it more simple and efficient for my construction using it.

Actual Behavior

Once pressing Union, the screen loads and in around 0.5-1 seconds, it prints me the information that CSG is printing the error code -11.

Hi Wither, I’m trying to reproduce this issue and having difficulty getting the error.

You mentioned on the other thread that it was happening on parts that were created on a previous release. If you create parts on this release, do they have the same problem? Do you have a file that you could share that has the problem?

Thanks!

Hello, I’m having this same issue with a script and it seems to be consistent with and without the CSG V3 beta enabled.

When I tested using the select tool and tried to union them there, studio instantly crashed. Though I’m pretty sure that’s an unrelated issue and not my main problem.

Hey @L3Norm, I have returned to this topic to report that I have reencountered the bug… As having two Union parts with 112 parts each in my experience “The Fallen”, I decided to merge them and in the LogService (the property where it sends texts at the Output tab), it printed the error -11:

It’s been a while but following up on this topic again…

We were able to repro the issue and should have a fix for this relatively soon.

It will require switching over to the newer / more robust GeometryService CSG APIs if you have not done so already (They are a clear superset of the old APIs so it should be as simple as switching some API calls)

We will report back on this thread once the fix is in for the GeometryService APIs. Thank you for reporting this and apologies for the delay in addressing this. (It was a gnarly one!)
