There are quite a few lighting mods worth looking at:
Relighting Skyrim by NovakDalton
Enhanced Light and Fixes by Volrath
Overhauling light source for ENB and vanilla by JawZ
And I think More Dynamic Shadows had some fixes for lighting as well.
Could someone create these mod threads please?
Maybe there we should create a thread to discuess this very thing? Admins? Yes, No? I don't think CoT brings as much to the table as RCRN does and from what I can tell most of us use RCRN. TC and Z have both created ENB's using it (TC exclusively with RCRN Plus).
I disagree Sairven, I think in its current form its perfectly ready for use. Right now it covers all of the interiors in towns, villages, and inns. I don't think this mod needs to cover all the caves and ruins for it to be valuable and consistent for the user. After all, other lighting mods already do that.
There is talk in STEP of jumping ship from CoT to RCRN or another lighting mod. I think before this mod is decided on, it should be clear which lighting mod will be with STEP in the near future.
Lighting/ENB/weather will likely be handled via STEP
Packs in the future (aside from 2.2.0b). This will allow for several options to suit a variety of tastes. All will be pretty cool, I think.
The SkyRealism ENB presets I made for the big three lighting mods are my own dabblings in this area. There are tons of combinations though, so we will be looking to the community for alternatives. We'll include instructions for authors creating these lighting STEP
Pack variants. One idea is to evaluate the best variants to be placed on the wiki as a supplement to the STEP
Guide ... there are far too many possible variants to include most, so the candidates will likely need to be classified by genera (fantasy, bleak, cinematic, realism, etc) and limited to the top pick for each.
This might conflict with anyone running RCRN as they already have dynamic lighting. Does anyone know if this would conflict with the realistic candle lighting mod that is already a part of STEP? (Real Effect Candle) Since this does more than candles it could be a replacement, although it doesn't work everywhere like Real Effect Candle does.
SkyRealism - Cinematic with RCRN - Classic and Real Effect Candle Mod.
I think that REC exacerbates the lightsprite *problem*, so not a big fan myself.
