Even though MeshPart’s have the Resize method, calling it and inputting a number will not do anything, you can however cause errors should input the wrong parameters. (At least that works)
Simple reproduction:
1.) Insert a MeshPart
2.) Run “game.Workspace.MeshPart:Resize(1, 10)” in workspace
3.) ???
4.) Observe as nothing happens.
