I found a bug related to meshparts that are guaranteed to crash studio 100% of the times. This is a Studio bug as you are required to have Studio’s scale tool in order to reproduce this bug. This bug will always occur if you are working with a mesh that is perfectly flat (an example of this would be a mesh such as a “plane”, whenever uploaded it would be sized x,0,x where x are arbitrary size values).
If you do not have access to make a simple flat mesh then here is a .rbxm and a .fbx with the same mesh
FlatPlaneMesh.rbxm (2.2 KB)
FlatPlaneMesh.fbx (10.8 KB)
Repro steps:
-
Create a mesh that is perfectly flat (if you use blender just insert a single “plane” and export it as a .fbx or use one of the files I provided above)
-
Insert the mesh into a meshpart.
-
Select the meshpart with the Roblox studio “Scale” tool (Ctrl + 3 is the default hotkey for this tool in studio)
-
Hold in “Shift” to scale the meshpart and select whatever handle it is that corresponds to my green colored handle as shown below.
-
Studio should now have stopped responding.
Additional information:
If you don’t hold in Shift when scaling the meshpart then you will get this result. So in order to repro this bug you are required to use Shift + Scale or else it will not work!
