I have run into a problem when testing my game. My game works fine in studio, but not in-game, for some reason the unions won’t load. I have posted this here because it’s just happening in my game.
What I’ve tried:
Publishing as a new place.
Copy, and pasting into a new place.
*Re-installing Roblox.
The unions are invisible for me in the file you sent, and attempting to separate one causes it to disappear. This means it’s corrupted, and to my knowledge, there is no way to fix it.
The only thing you might be able to do is to fish through previous versions of the game or file, if you have them at hand, for ones that aren’t corrupted.
For this reason, it’s usually best to:
build without unions where possible
leave any unioning work to be done for toward the end of the build
For a work-around to this issue, a good tool to learn is blender. Meshes are the same as unions but just made differently. They are very customise-able, allowing many shapes unions just can’t recreate. Plus: you can also UV unwrap them and add textures, allowing for all sorts of details.
Personally, I’d recommend steering clear of unions altogether. If you can get away with it, use wedges and parts to replace unions or even meshes.
