"Enhanced lighting system for the Sims 2. Uses physics laws of light
to ensure the most realistic lighting possible within The Sims 2."


2.4 APL-29
-Added optional files. 2 types of unlit room darknesses and a balance to all lights
-removed indoor sunlight color saturation.
-Increased unlit room brightness at night
-Decreased orb lights and few table lamps diffusive Strength
-Changed two street light colors from yellow to white
-Adjusted Sims and object overall light strength
-Adjusted seasons, morning, and evening
-Adjusted winter, Spring, and Fall indoor portal spill to match better with summer
-Adjusted cloudy day, will now resemble winter as but a bit darker and grey
-Fixed street lamp from M and G from casting a very weak light, again


This is all based on Gunmod's Radiance Light System 2.1 and 2.2 made compatible for all expansion packs including stuff packs. I've included the pool shader from 2.2, It should not be used with Seasons if you have useshaders on true. All credit belongs to Gunmod, Previous versions are not needed.

General Changes from 2.2:
>Compatibility for all EP's and SP’s
>Specular highlights for indoors and with usershaders on.
>Fixes to errors found on certain objects and lamps in base game.
>Corrected Dance and Neon lights and color.
>Adjustments to Day, night, Seasons and weather.

>Adjustments to Archways and Glass doors to make them cast more correctly.
>Adjustments to all light objects and windows.
>Adjustments to Userstartup.cheat
>Increase all light brightness and fallout range.
>Increase Doors and windows fallout range.

I noticed in the installation description that some folders in the /EA GAMES folder get overwritten? I have empty templates, so I'm wondering if this mod will affect and/or overwrite them? Thanks in advance. PS. I plan to use the Scriptorium method of installation btw, not the manual.

This may need to either be put in beta 1.5 or 1.4a, when taking photo booth pictures, the pictures become "over exposed" so to speak, or better yet, you get a silhouette of the sim when the photo booth pictures come out.

Wow this mod is really realistic!!! I downloaded it then played a few of my houses and my lighting now is way better than the Maxis lighting. I really enjoy also having dawn and dusk now it looks real nice. And night now is really darker than before, I saw that I have a moon and stars which I never knew I had!

Well thanks so much for this its great, S.R. Home Designs

daydream_queen - Niol's pond water mods work fine for me. Use this, not in the thread with Targa's stuff. I've got all EPs and have been using this mod and Niol's together just fine. The issue with chris997's mod is also unrelated to this one - you need to turn your view distance in your game options to max, otherwise the skies will look like the default.

Update: So I went ahead and installed it manually, and to my relief, it didn't overwrite my empty templates because the mod only alters one folder in each EP...*ahhh

Anyway, cool mod. Thank you.

HP, I am having the same issue you're having with custom lights being way too bright. Have you found a personal work-around for this? I really want to keep my custom lights in the house for decor reasons, but maybe I can turn them off and use Maxis ceiling lights or something? Any suggestions would be very helpful .

it is fixable but when I reduced it, it also further reduced how lights were casting when there are multiple windows next to each other. I'll still be trying to find a workaround for this.

I haven't tried reflective floors yet. The shaders shouldn't be conflicting with each other as they are affecting different things. a least what I know.

Changing sealed room shadows will also affect every other shadow darkness in the game. as I find it best to keep it at the desired setting it is already at. This is a limitation with foundations and decks that are treated as a portal. Lighting on the foundation will not affect the walls above or below it. and are your using smarter lightings?

I may have to readjust the outside night global lighting as well as lamps as they will all get affected by this.

No, but that a great idea.

only thing it gets over written is the lights folder. as long as it came directly from the zip. For custom lights you might have to create a new .txt containing the lights objects lighting profile and have it use lighting profiles from RLS instead. I don't know any easier method than this.

I've tested it and I was unable to get that problem. It was resolved during the pre-beta stage. Re-install the mod and try again.

One thing I absolutely LOVE about this mod is the way the outdoor flood lights actually work how they're supposed to! In the screencap there you can see the red lines where the floodlights hit Huge Bill, and the blue lines where they hit the Breadfruit Tree in the background. Previously when I tried to light something big like this up I could light up the knees and not much else no matter how far back I put the light. And the other thing that shocked me is how this mod stops the light from shining BEHIND the light when its pointed in a given direction. Before now it had a normal flood effect like a table lamp but now its really realistic.

One thing I'd like to know is if you could make a mod of these lights (not a global one) so that the light's brightness and intesity stays constant (i.e., lighting up a wall on the third floor from the ground) Not that you have to but I think if you can get this done that's probably just a hop and a skip away.

a potential alternative is to heighten the grid points next to the wall bottom and tops all the way up high to increase such likelihood.

When I go into lots everything is pitch black. I have to put in alot od lights to see. Is this normal? If not how can I fix it?

EDIT: Answered my own question. Changed lighting to high. Hehe, silly me.

Interesting to see this updated again. I used to use it before Seasons but it was d-a-r-k. Now, however, I have a new computer with lots of RAMz, whizzy graphics card and other high end goodies so I'll give it a try again. I've been meaning to reinstall the Scriptorium anyway. Kudos to you (and Numenor).

I have to say I was reeeally nervous about installing this. I've used GunMod's 1st Radiance Lighting mod for the longest...but BOY am I HAPPY I installed this one!

The lighting in my game is phenomenal! The stormy weather looks so cloudy, dismal and gray outside. You can tell it's about to storm.

The lighting is soooo realistic inside and outside my homes. I can't stop taking pictures. I especially LOVE the way my Sims' homes look inside at nighttime, now.

This pic was taken around 1 am. I didn't add any brightness to the pic in PSP, either. Just sharpness. And you can see the light still spills over into the livingroom even though there's a floor edge between the kitchen/living.

I use Smarter Lights with this, and it really looks great.

I'm overjoyed with this mod, thank you SO MUCH!

The Sims 2
The Sims 2 Pets
The Sims 2 Seasons

does AnyGameStarter create its own files the in the ea games? I remember putting the lighting files in there to test it on stand alone expansions. Might have been something else though.
do you have The Sims 2, Pets and Seasons inside your config folder? there not suppose to be in there. I don't know what unknowns.txt as it doesn't use that. Check whats inside of it or delete it. If you don't have a userStartup file you can just use the one in the zip.

I absolutely love the lighting in the game, but sometimes THIS happens to me:

Objects black in a room that should be dark (usually occurs after someone exited it)

Any idea why? It's been happening for the past coupla weeks now, usually in the early morning (between 1am and 4am). I mean, it's a minor annoyance because it never lasts that long, but I would still like to nip it in the bud. FYI: I also have the SmarterLights hack installed, and I have every EP up to FT installed. Lighting and shadows are all on high.

Thanks in advance.

It seems to be an issue with smarter lights. I've noticed without it, lots will light up on both objects and such correctly. Although you will be losing the effects of the new auto lights. You might want to try it without smarter lights and see if it helps.

I figured it was probably SL. You mean try it "without" it? I will remove it and see if it helps. Pity though...the hacks work great together.
