I can't figure out how to use Arma 3's spectator mode without having seagulls spawn in all over the place (giving away where players have died).

Removing the seagull spawn would make the spectator mode viable for PvP play.

EDIT:

For anyone looking for a work-around, you can add the file "onPlayerRespawn.sqf" to your mission folder, and within put:

{if(_x isKindOf "seagull")then{_x setPos [0,0,100]};
}forEach nearestObjects [player, [], 250];

It's a bit crude, basically just moving the seagull to the bottom-left of the map, but it seems to work fine when using the respawn template "spectator".

i thought that they already did that, anyways, you can find a way around it, and i like seagulls, so downvoted.

Who doesn't love seagulls? Still it feels really weird that they aren't disabled by default when using the spectator mode. You can instantly see where and if people have died by gazing at the sky, which has tons of implications in some game modes.

Still present with GROUP respawn after no AI left - and quite silly!
