Question: Why does roblox studio delete my model vertices?

Hello,
I am trying to make cool story-FPS, horror game and I have one problem. When I tried to upload revolver in my game then roblox studio deleted some vertices from this model. I tried to look to the blender but there wasn’t any problem. Can’t anybody help me here?


Feel free to reply.

Studio isn’t doing anything wrong, you have your Faces inverted in Blender.
Google “Blender show normals” since this is an issue with your Blender mesh, not a Roblox issue.

in the mesh properties, select “Double Sided”

as a quick fix but not great practice to rely on

OP go to mesh > normals > recalculate outside

As @MP3Face stated, if you make it DoubleSided then it effectively makes the Mesh render with double the number of Faces it requires. Do this enough and your game’s performance may suffer.

On another note, I recommend you select all the Faces you want smooth and select Face>SmoothFaces. The flat “curved” surfaces of your gun won’t show the sharp edges anymore.

Hello,
your advice was good too. Just Blender developers changed some controls in version 2.93.1, so new shortcut for “Normals” was Shift+N.
