Is there a mod that fixes this and determines how easily they can detect you depending on the light sources? Since sneak internally uses detection depending on light sources can this be done? For example, if an NPC is holding a lit torch he would be able to detect anything nearby that is within or near the light source given out from the torch. On the other hand the player sitting there in the dark can see the NPC but the NPC can not see him because there needs to be that light source or being close enough to the NPC it would be obvious he would notice something moving. Then the other way around, if the player is holding a torch and the NPC is not, the players light source would be giving out a much larger radius to be noticed. Same would go if the NPC was also holding a torch, it would make no difference.
Most of this probably made no sense, but I just think NPC/monster spotting me in pitch black darkness kind of svcks and hoping there has been some sort of mod that has implemented something similar to this. i have noticed a few mods that make sneaking with a lightsource give yourself away. I know that light sources must play some kind of factor in Oblivion since it does with Sneak so could it possibly be expanded beyond just sneak?
I will be looking into this further as maybe I could consider making it myself but it typically takes me a few weeks just to get down the basics of modding for any game I ever have.
Thanks
