CVARs
Console variables (CVARs) can be used to set various editor and runtime options in O3DE. O3DE ships with many built-in CVARs.
Working with CVARs
You can define your own CVARs in code using the CVAR macro functions .
You can invoke CVARs in the Editor via the console .
You can also pass CVARs on the command line when launching O3DE binaries via --{cvar name} {value} or --{cvar name}={value}. For example, ServerLauncher.exe --sv_somebool=true.
Common CVAR prefixes
O3DE prefers to use the following prefixes for certain groups of CVARs:
