How can I make it so that Hornet Race can not be selected as the game type for my map? I've added all the race initial spawns, respawns and checkpoints and labled all of the spawns and respawns as race_driving, but hornet race still shows up as an available game type when I play a custom game. My map is really only suited for driving, not flying of any kind. Does anyone know how I can ensure Hornet race is not a selectable game type for my map?
There is no way to do that. If the overall gametype is available on the map (Territories, Race, etc) then all variants will be too. It's pretty clear that a race map is not for flying gamemodes unless specially noted, so you should be ok.
