So I have been playing around with the mission editor allot more today and there is one thing I still can't get to work, I have looked up tutorials, tried a 1000 different ways and I get the same result. Every time I try to set troops to embark on the player helo, they run around a bit usually not in the direction of the helicopter then stop and do nothing, I also notice I don't have the radio option to embark troops. Any advice would be greatly appreciated I'm still learning this mission editor and its allot different from say ArmA 3. Here are a couple photos to maybe help diagnose the issue. btw was not sure if this post went in the Missions section or Belsimtek Mi-8MTV2 so apologies if its in the wrong place. EDIT: I just noticed there is a mission builders sub forum...oops..

Yeah after I posted this I found the option in the options under game play tab, was hoping for a key in game to flip them on or off. Thanks for the speedy replies.:)

I was hoping to gain a little FPS boost by disabling them but I cant find a key stroke or option, am I missing something or can you not disable them or flip them up or something? As I believe this is my first post here I hope its in the right place.:P
