Hello… I’ve been facing an issue with my ROBLOX Studio…
I had built a few models, and as you can see there are parts in the workspace which aren’t visible, I checked the transparency, I checked in Test Mode, and I even tried turning off all my plugins and trying it in a new Baseplate.
I’m completely unsure on how this happened, and if other people are having this issue as well, I’d like to see if we can find a solution.
I’ve actually encountered this same problem many times. I’m almost certain the problem you are dealing with are unions.
It’s a really annoying bug. Try separating the union, I don’t remember if this worked or not but give it a try anyways. If it doesn’t work, you just have to remake it. You should try to keep a model file of it saved just in case if these things ever happen. You could also try to revert the version of the place.
Never trust unions, I almost never use unions anymore; they are high poly, lag your game, and in my opinion don’t fit the overall Roblox style. Stick to parts, you can achieve the same shapes without unions.
Unions if many are used or really any, have a chance of being corrupted. My best bet is exporting the parts to Blender and re-importing them as a mesh.
