So the monitor works fine and I can place it but when I try to place a camera it creates an error and if I go into the console to find whats happening it says this:[RT Camera] lua/weapons/gmod_tool/stools/rtcam.lua:75: attempt to call method 'SetKey' (a nil value)
1. LeftClick - lua/weapons/gmod_tool/stools/rtcam.lua:75
2. unknown - gamemodes/sandbox/entities/weapons/gmod_tool/shared.lua:240 (x21)
