Is it possible to change the AI's view distance, so that when you are outside in an open field, they can see you from far and also hear an explosion in your area from afar. Obviously it would have be tweaked for indoors. Is there a script that can do this? I find if this could be possible, sneaking would be harder and would make the player more careful where he/she steps.

Yeah you can edit FSneakExteriorDistanceMult and FSneakMaxDistance for starters.

Pretty much every overhaul tweaks detection distances.

why hasn't anyone tried this with realism mods? I think its one of the biggest flaws regarding stealth.

well i havent experienced any like that. I was hoping Arwen could implement this feature as soon as she has time for it of course. She has been working hard on her module for a while, so I can wait.

- Sneaking is now much more realistic, making stealth game play more effective, but also more difficult (especially with low Sneak skills during the brightest time of day). It is now easier to remain hidden in darkness/shadows; and it is now possible to re-hide after being detected (but it can be very difficult to re-hide, once the enemy locks on to you). And your sneak skill level is now a much greater factor in your ability to remain undetected, and your Perception stat is now a much greater factor in your ability to sense enemies further away.
- But your PipBoy Light is finally a decent light which will now enable you to find your way, even on the darkest night. The light is now 3 times brighter, illuminates twice the radius, but has much less glare (so you will not be blinded by an indoor light that is way too intense).
- My Dynamic Stealth Script: Uses separate stealth values for interiors vs. exteriors, time of day now dynamically affects your ability to avoid detection (finally makes it just as hard for the NPCs to see you in the dark), and weather conditions now dynamically affects your ability to avoid detection (you will be a bit harder to spot when it is cloudy, and even harder to spot when it is raining or snowing, and very hard to spot on a rainy/snowy night).
- NPCs will be a bit more alert to your presence, will stay alert longer, will spend more time looking for you, and will search a much greater area for you (up to 4 times further than in the default game). NPCs will detect you if they get close (they will no longer stand right in front of you without seeing you). And when you are hiding in the shadows, the enemy will detect you if you move when they are nearby.
- Doubled the detection of noise that you make while sneaking. Running makes 3 times more noise than when walking - unless player has Silent Running perk (default was only 50% more). But it is now easier to be stealthy when wearing lighter armor (under 11 pounds), while it is now much more difficult to be stealthy when wearing heavier armor (over 11 pounds). Plus NPCs will now sleep a bit sounder - they will not wake up quite as easy when you are nearby
- NPCs will now respond to explosions from much further away (2.5 times the distance in the default game). And if you fire a gun, anyone nearby will know exactly where you are (no more picking off enemies one at a time, while they all just stand there). But guns with silencers will not give away your location, unless NPCs are very close (they will focus their search on where the bullet hit, which you can use to distract them).
- Other Stealth changes: Your PipBoy Light will now make you very visible; and other player actions (such as jumping and opening doors) will now alert your enemies.

But what about not sneaking? I find myself walking along and see a bunch of raiders a long distance out. They can't see me even in danger mode, plus I can shoot a bunch of them with almost no reaction. Besides them running over to look at the dead guy I just shot. I uses responsive kill reactions with arwens. Anyone know if this has something to do with it? Couldn't figure out if RKR was suppose to go before or after arwens tweaks =/
