Testers Wanted: Seasons Atmospheric Lighting Tweak

I absolutely love the seasonal lighting that they introduced as part of Seasons, but I found the exact settings for the defaults were not exactly to my liking. Therefore, I tweaked things a little bit to make things more like how I want them.

The changes I have made are VERY subtle (as is the lighting to begin with, honestly) so rather than viewing my comparison picture which is attached, please see these individual pics so you can flip back and forth and see the difference:

Default-Spring / Tweaked-Spring
Default-Summer / Tweaked-Summer
Default-Autumn / Tweaked-Autumn
Default-Winter / Tweaked-Winter

My changes are intended to lessen the over-saturated golden yellow of spring and make it a bit more green, but still quite warm and bright. Summer has been taken from, well, what looks like default lighting to a warmer pale orangey yellow, to give a sense of heat. Autumn looked like sunset all the time to me before, so it has been given a nice golden tint with a touch of grey, which goes nicely with the leaves but still feels cool. Winter I've left the colouration roughly the same, just darkened things a smidge so it feels a little more dreary.

I have not changed the sky tint whatsoever - my changes that I tried to make to the skies didn't seem to work. I will continue fiddling with that. I also am trying to change the storm effects for darker storms, and I'll post an updated version when/if I can figure out how to make that work. I'd also like to make nights darker and less blue. Consider this version 1, to "fix" the effects for more atmospheric gameplay, pending more fiddling and tweaking and many many in-game tests. I will likely be doing several flavors for different preferences and styles, so watch this space.

Radiance Lighting: This version is not meant to work with Radiance Lighting, as Radiance is not fully compatible with Seasons (just check out a lot with heavy snow at sunset and you'll see what I mean) - however, it SHOULD still work even if you have Radiance installed. I just advise against using Radiance with Seasons right now as it looks, well, weird.

You will likely need your Lighting settings turned up to high to see the seasonal change effects, and a decent enough graphics card to handle it. If you can see the seasonal lighting without this modification, you'll be able to see it with it.


1. Go to Program Files\EA GAMES\The Sims 2 Seasons\TSData\Res\Lights
2. Copy the file Lighting.txt
3. Paste the "Copy of Lighting.txt" file into the Lights folder.
4. Rename that file to LightingBackup.txt
5. Now from my rar file, copy Lighting.txt and OriginalLighting.txt to Program Files\EA GAMES\The Sims 2 Seasons\TSData\Res\Lights
6. When it asks if you would like to overwrite Lighting.txt say YES.
7. Run the game. Your seasonal lighting effects should now be tweaked.


1. Go to Program Files\EA GAMES\The Sims 2 Seasons\TSData\Res\Lights
2. Delete the file Lighting.txt
3. Rename your LightingBackup.txt file to Lighting.txt
4. Run the game. The original seasonal lighting effects should be back.


I have included my copy of my original lighting file (OriginalLighting.txt) just in case you either forget to make a backup (by the way, MAKE A BACKUP!!) of your own file - you should be able to use it instead of your LightingBackup.txt file if you want to restore the original lighting. But seriously, back up yours. It's just better that way.

Please note that this mod is QUITE experimental. I make pretty dresses and hair - I just wanted prettier seasonal effects for my game, so I'm sharing my tweaks for my personal use with ya'll. I realize that the exact tweaks are personal preference. If you would like to tweak the seasonal lighting to your own liking, it's VERY easy, and I have basic instructions on doing so posted here.

To be sincere i like how the atmosphere is in the game(especially the spring yellow lol), but people have different tastes so this will be certainly useful for others ;-) Thanks HP!

I can't see any difference in the pics, but I'll test it out for you - I know the pics don't always do the item justice

this is great HP...but I noticed in game that each season has two colors, early in the day in spring it can be a slightly yellow tone, but as it approaches noon-2 o clock it gets a bit more white. Same with the other seasons. Dose this address that?

Just checked the links in-post and I can see the differences now - looks much better already, can't wait to check it in-game, cheers

Thanks. I hated the yellow light in Spring especially. It's not too good for contests.
#7 Old 12th Mar 2007 at 5:27 AM
Ah yes, my good pal Hysti! I'll definitely be trying this. I agree--there's a tad too much saturation on some of the seasons. This fix will be subtle, but I'm thinking it'll nevertheless be worthwhile. I guess if I really want it much better than this, I'll just have to wait until 2009.

sim~obsessor, the change in lighting effects through the day is handled by a different lighting file that has not been modified (that file is from the base game). The daytime/nighttime/morning/evening effects appear to modify whatever the seasonal effects are, so you will still get a slightly different light quality at sunrise and sunset, but the overall tint should still be modified properly.

CormorantEnt, if there are effects or tints you prefer, it's -VERY- easy to change. Doesn't even need SimPE. I linked to the thread where I started discussing the seasonal lighting effects on S2C, where I posted instructions. All you need is something to get the RGB values (Photoshop or any graphics editor - even websites that list RGB codes for colours), a calculator to convert the numbers (divide the RGB values by 255), and Notepad to open the Lighting.txt file.

I meant...too much the original. Yours is just fine. Sorry for not clarifying. ;-) By waiting till 2009, I meant when The Sims 3 is scheduled for release.

You're getting this about as good as it's gonna get given the limitations of the second-generation game. To improve any more, we'd almost have to wait for the third-generation game to be released.

We can crunch numbers to fix lighting all we like, and build all the custom skintones in the world, but even at their best, not even GunMod and Chocolate Pi could fix everything. At her best, Helaene cannot fix how silly animations in-game distort the beauty of her details.

Yes, we know how to fix GraphicRules.sgr so it doesn't destroy textures. The issue is, that the fixes are even necessary in the first place. For that to go away, we simply have to wait for Maxis to do what it does best--improve on its original design.

I love the Tweaked Winter one. It looks much more icy and bitter, which happens to be the perfect Winter atmosphere IMHO.

Excellent work.

Being a Photoshop addict, I notice a HUGE difference between each pic! I might be getting seasons, if I do then I will definately d/l this! Thanks and well done, it looks very realistic!

Default Thanks So Much!
You are amazing! The coloring looks a lot more realistic.I love your default skins in my game as well, for the same reason.
The skintones are now so much richer,and I KNOW that this will look awesome in the game as well! Thanks so much!

OK I might be a complete moron but, when I go to the Lighting folder as you directed my lighting file is a package file not txt so when i added this in it didn't overwrite it since they are different types.
#17 Old 25th Apr 2007 at 9:06 AM
You looked in the wrong folder. Use Lights, not Lighting.

1.Hello, HystericalParoxysm!
2.Can you make the Bon Voyage version, If necessary (afraid
to test it, because don't wanna crash the game)
3.Oh, and before the 2. - does this work with Bon Voyage?

1. Hi Ralfijs

2. I don't have Bon Voyage. I'm not really planning on getting it.

3. No idea, not having Bon Voyage. I would guess that if you only replaced the one lighting file and no others, it'd probably still work, but I have no way to test that.

Hi, HP! I absolutely love your stuff, in general, and I've decided to try this one. I've kept the original settings for winter, since I already found the Maxis winter too dreary, but I love your other tweaks. I was a bit weirded out by the yellow light in spring, too. I mean, I live in a very warm country, and even here spring doesn't look like that.
Anyway, thanks for this mod!

One of the great things about modding is that you can tweak a game to be exactly how you like it, and this is a perfect example of just such a tweak. I always thought autumn and spring were a bit too "orange".

I can see quite a bit of care has gone into this creation, good job.

It occurs to me that I don't *post* thanks enough I use almost all of your stuff, and never seem to get around to doing more than hitting the button. Eternal lurker.

And alas, I'm being true to form now, because mostly I'm posting to ask where the tutorial for this has gone: I'm interested to see if I could tweak it to change the colour of the sky in a more drastic manner. Unfortunately, the thread seems to have disappeared, and five searches have failed to locate it.
