Unless I'm mistaken, there are 2 different types of markers that NPC's will interact with while on a sandbox package: Furniture markers and Idle Markers. Furniture markers obviously include furniture like chairs, beds, bunks and so forth, but they also include markers like push-ups, leaning on a wall, leaning on a rail and tending bar etc. These markers are NOT a piece of furniture but for whatever reason they are still called furniture markers and are listed in the furniture section of objects.
Then there are Idle Markers that are the flat, blue squares that you place on the floor and have a big I in the middle. They are like the Rivet City Museum Idle marker where an NPC will walk up to it and pause for a bit and act like they are looking at the museum displays. There are others you can set to cause an NPC to stop and sweep the floor, smoke a cigarette and even pick their nose, lol.
The issue I'm having is that (just like in FO3) the vanilla companions will NOT interact with the Idle markers no matter what I try. On the other hand, they will hit and idle at EVERY furniture marker I place in the room. My custom NPC's will hit all of them, but for some reason the vanilla companions will NOT use the Idle markers, only the furniture markers.
Does anyone know why and how to fix it? And, yes, everything is checked including idle markers in their sandbox package. The reason this is important to me is that I have a little museum of sorts that I want the vanilla companions to wander around in sometimes and act like they are looking at the displays. The only way I have been able to make them go in there and fart around is by placing furniture markers (like warm up by fire) in there. But they look stupid doing that animation in my display room.
