Rt camera help

I saw this on a old post and nobody replyed. When i was recently playing garrys mod my RT cameras are were working. When i pressed the button the camera to view on full screen it wasn’t working.

This is the error code it gave me.
[@gamemodes\sandbox\entities\gmod_rtcameraprop\int. lua:89]bad argument #1 to ‘random’ (intreval is empty)

I’d really appreciate it if you could help me.

:doh:

RT cameras can’t go fullscreen. Spawn an RT screen to use them.
