VRChat U# - Access Trigger System (Patreon)

What we utilize a string that we call

"public string[] allowedUsers;"

Remember that the Name that is this field needs to be a exact match to how it is in VRChat. 

A username that is "Abc123"
Is not the same as
"abc123"

Import the script and place it on any object, It will turn itself into a interact button.
