CSGO: cl_leveloverview - black / green screen

Hi

I'm working on a map and wanted to add a Radar. I've followed the instructions shown here: https://developer.valvesoftware.com/...evel_Overviews

Unfortunately, when I'm trying to work with cl_leveloverview, I get a black screen (Game is still working, but I cannot see the map).

I've tried different values. When the value is low enough, I get a green screen with some parts (to be exact: The lowest func_detail parts) of the map.

I am not able to see the whole map, no matter what value.

What am I doing wrong?

Thanks,

Marc

ah well, I joined as spectator and not as a player with noclip... that was the problem. Thanks!
