Superfreeze
Toolmode to completely disable movement of objects.
Superfreezing an object will prevent movement, saving on performance and getting rid of the floaty movement when walking on top. Great for bases, rollercoasters, space stations or just about anything that remains stationary.
Primary fire will completely disable movement on an object
Secondary fire wil resume movement
Reload will put an object to sleep, a "soft freeze"
Holding your sprint key will apply these effects to all constrained objects.
Primary fire on a NPC will mark them to have their ragdoll frozen the moment they die, secondary to unmark.
If you’re a server owner or just playing singleplayer and know some Lua you can edit Precision Alignment to allow superfrozen props to be moved by going over its files and replacing every util.IsValidPhsyicsObject(ent,#) with IsValid(ent:GetPhysicsObject())
