Even if I import the mesh from my computer, it is not uploaded at all with the error message below.
The mesh doesn’t even upload to Roblox at all.
It does not seem to be a triangle problem, a problem with the obj model itself, or a problem with the obj name. Because even though I tried all of these things, it didn’t work.
Even after reinstalling the studio, the issue continues to occur.
It is a group creation project, and our developers are experiencing the same problem. (Even in their own personal studio projects)
