So I've been using RTMS to make some screenshots, particularly on SP maps, but when I'm seen by monsters, it tends to ruin good shots. Even if I use invisibility, smarter enemies like Skaarj are able to see through it. Are there any mods that allow monsters to completely ignore the player? Yes, I know I could just remove them and replace monsters accordingly, but then there's the issue of them being on an angle or seeing me immediately.

The cheat combination playersonly/ghost is no option?

PS: What is RTMS?

RTMS is Real-Time Movie Studio. A Tool used for making Machinimas.

And Ghost/Playersonly could work, but most of my Screenshots are on EXU2 and G59, meaning that If I look at the map slightly wrong, I'll get the Occlude:Renderframe crash due to their immense detail.
