Ok. I made this crappy hat mesh for my roblox game.
I have the hat in replicated storage.
I don't know if this has to do with cloning the model it's in, but it gets all messed up (had this issue in another game too).
Here is the hat before test: https://imgur.com/7g2snD1
Here is the hat after test: https://imgur.com/XedVO9j
PS: It is broken when I test the real game too!
This mesh seems like it has no texture, and the blue color looks like it might be glass, ice, or foil texture. Simply: -Create a texture for your hat: I see you might have done that?
-Have a script set the color of the hat using the BrickColor or Color3.new.
