I did as much research as I could before making a Forum Post about this issue.
When I was working on my Build I noticed every time I published a game to Roblox all unions get corrupted, if I try to separate them, the unions just delete. I’ve known about this issue happening to other people but never because publishing is the root of there problem, this only started recently and I have had to re-create all of my unions before I realized I should make backups before publishing.
Okay so, instead of using that many parts to form that shape for a Union, WHICH WILL ADD A HUGE AMOUNT OF ADDITIONAL LAG! You could make that shape in Blender in the slightest bit of time. If you have any more questions I’d happily answer them, on how to do this, and some tutorials you can watch.
It seems to be a temporary glitch I’ve mentioned before where you union, try to publish and it disappears. If you restart Studio then go back, your union should still be there. Now if it disappears altogether even after starting the whole application, your problem is an entirely new breed.
And slightly off topic but is it just me or has Studio been incrementally becoming more and more unusable within the past few months for building?
