No Animations

Stops the game from trying to replicate your animations in the server. You dont have animations in the server but you do for your client

{
    "DFIntReplicatorAnimationTrackLimitPerAnimator": "-1"
}

Max Raycast Distance

Raycasting is the use of intersection tests to solve problems in ROBLOX. The most common use of raycasting is to determine the first object intersected by a ray. This is done by casting a virtual ray from a certain point in a direction and determining the first surface it intersected with.

{
    "DFIntS2PhysicsSenderRate": "-30"
}

Invisible 2

Locks your character's position on the server to (0, 0, 0), having the side effect of turning you invisible. This only affects the server and other clients, not you. server-sided things that rely on your position, like clicking to get tools, will not function. In some games these can be abusable.

{
    "DFIntGameNetPVHeaderTranslationZeroCutoffExponent": "10"
}

Invisible 3 (BEST INVISIBLE)
