I take pictures using Fraps, so everything I don't hide shows up i my screenshots. What I'm wondering is if there's a way to hide the little round green icon that comes up when you're not directly looking at your active sim, the one with the white bar that moves around depending where the sim is. I'm sorry I don't know the proper name for it, but it keeps showing in my pictures and it's annoying to edit it out.

Press "c" on your keyboard to take screenshots without the UI. Only things that will show up are thought/speech bubbles and the green icon that appears above your active sim's head.

"hideheadlineeffects on" will hide the plumbob and any speech or thought bubbles over Sims' heads
"maptags off" will hide map tags- I believe you need to use "testingcheatsenabled true" first to use this one
