Unions Consistently Fail to Load: HTTP 404

Help and Feedback Building Support

I’m currently trying to model some in-game items, but unions are consistently failing to load.
Whenever I create a Union and then attempt to save the game, I encounter the following error:

Mesh Manager: http request failed, contentid: 'https://www.roblox.com//asset/?id=4990415408', exception: HTTP 404 (Not Found)

I’ve tried the following, all of which have failed:

  • Waiting after creating the union, and then saving
  • Moving the parts of the union
  • Trying with a different union

At this point, I’m essentially unable to make any unions at all, which is greatly hampering my ability to model. I’ve looked through older posts but I can’t find any functional solution.

Any assistance would be appreciated.

There is a big issue lately, with unions getting corrupted very easily.
Seems as that is what happens to you, too.

Sadly, I don’t know any way around this, or any way to revert back corrupted unions.

For now, we kind of are obligated by Roblox to switch to 3rd Party Software to create complicated parts.

At least that side is supported.

Thanks for your reply. Since this post, I’ve found a solution, albeit a weird one.
What I’ve taken to doing is exporting my unions and then re-importing them as meshes, then inserting the re-imported ones and deleting the originals.
That seems to fix the issue, and I can save the game without them vanishing.
