Transparent No Camera Glitch Parts

Hello.
So I am making a roleplay style game on which we have a lot of tech without a player whitelist.

How can I make a part completely invisible whilst making the players camera not being able to glitch through.

Any advice would help.

if i understand right this is what you are searching for

You can achieve this by inserting a SpecialMesh into a visible part, change the MeshType to FileMesh and set the scale to 0, 0, 0
