Research on Global Lighting

In order to keep tatlopuyo's thread cleaner so that he can use it for releases and previews and user comments, I've created this thread so that the community can provide its collective research on any lighting parameters we can discover inside the global.iff file.

Tools you may want to use:
Global Editor - http://www.mediafire.com/download.php?zi783vl61w43ozb
Recurring Hex Patterns - http://www.mediafire.com/download.php?eb524c5l72iz5br

The first one is an automated tool that changes the lighting parameters that we already know about, and can also give you the float value of a hex string or the hex string of a float value.
The second one looks for recurring hex strings in any file's binary data, and gives you the float values those contain, if any. The result is saved in "My Documents\Recurring Hex\log.txt". In the same folder you'll find a "log_normal.txt" which only contains hex strings that contain a float value in the "normal" range. That means it skips all lines of the original log that contain "#E-#" or "#E+#" or "NaN". Float values that contain "#E-#" or "#E+#" are actually floats, but they're too small or too big to be lighting values normally. I doubt that the programmers used a lighting parameter of 3.82*10^-26. Still, if you want to take a look at those as well, you'll find the "log_allnumeric.txt" file contains all the lines of the original log that don't contain a NaN (not a number).

So, the first set of parameters that tatlopuyo discovered are a pair of floats with a hex string of "000040BF6666863F". This pair occurs 96 times inside the global, and has been proven to affect lighting. What I'm trying to do is discover other values that could also affect lighting. Using the Recurring Hex Patterns tool, here's what I've got. In the following quotes, I'm only including float values that are in a "normal" range and don't require a power of 10 to be represented.

12-byte sets that contain 3 float values, including the two we know about (ignore the line number; first number after the line number is the times each hex string occurs).

Line 10387: 36 0000803E000040BF6666863F 0.25 -0.75 1.05
Line 15878: 24 CDCCCC3E000040BF6666863F 0.4 -0.75 1.05
Line 18663: 20 000040BF6666863F9A99993E -0.75 1.05 0.3
Line 32336: 12 000040BF6666863FE4380E3F -0.75 1.05 0.5555556
Line 35452: 12 00004040000040BF6666863F 3 -0.75 1.05
Line 205899: 4 000040BF6666863F0000803F -0.75 1.05 1

Here's what's interesting about this table. If we ignore the 4th line (the one with the 0.5555556, which is the least probable number to be an actual lighting value), the other lines sum up to 96. However, the parameters are sometimes after the two lighting values we know, and sometimes before. Still, judging from their values and the total times they occur, they could be lighting parameters.

16-byte sets that contain 4 float values, including the two we know about.

Line 153968: 4 000040BF6666863F9A99993E000080BF -0.75 1.05 0.3 -1

4-byte sets that contain 1 float value, occuring 96 times.

Line 6295: 96 FC9BF23F 1.895385

Line 6344: 96 5855D53F 1.666667
Line 6346: 96 9A99CD41 25.7

If you ask me, of the above only FC9BF23F and 5855D53F seem to be in the range 2K usually uses for lighting values. The other are too large or too small. 2DBC6EBC could be as well.
Still, the above doesn't say much, because the values used for the lighting parameter could show up more than 96 times. The below table is more interesting though.

8-byte sets that contain 2 float values, occuring 96 times.

Line 4513: 96 000040BF6666863F -0.75 1.05
Line 4533: 96 0000803FCDCCCC3D 1 0.1
Line 4542: 96 000000009A99CD41 0 25.7
Line 4551: 96 0000504100009641 13 18.75

First one is the one we already know about. Third and fourth look suspicious, due to their large values. The second one however could be a pair of lighting values. It occurs 96 times and is in the range 2K uses.

good stuff, but when I was manually checking parameters in the uniform files, I found that if the float was an exact number, like 25.7 or 18.75, it controlled something. Also, I did run into infinite repeating numbers like the 58.3333 or 1.666667, so I don't think those should be discounted either since they represent 1/3, 2/3, ot 5/9 for the .5555555556 one.

This is some very useful stuff though, thank you

here are new values that changes the lighting/shadow effects on the players.. 9A 99 19 3E 00 00 80 3E..it appears about 101 times..combine this with the previous one 00 40 BF 66 66 86 3F and you can fully edit the shadows lighting..its amazing..try to play around with it..

i tested it again without changing the values of 00 40 BF 66 66 86 3F and just changing the values 9A 99 19 3E 00 00 80 3E...i think thats what we are all looking for..shadow mod without change of lighting to the players.its awesome..try it..

Awesome news. I'll implement the values in the Editor tonight so that we can all experiment.

thanks leftos..im experementing on it right now..but i got the shadows without change of skin tones..and it adds glow..but right now its too yellowish..wait..ill show you a quick screenshot..

effects are noticable and theres a certain glow on players...we just need to find the right values..

here is another screenshot of the effects you will get when you change 9A 99 19 3E 00 00 80 3E...i know the color is not good but you can definitely see the difference than the default one.. ill play with it again later when i wake up..hope you guys can find the right values for that by that time..it will save me some work..tomorrow ill also share the the offsets where you can change the ball effects..

The 2 new parameters have been implemented, v0.3 of the Global Editor has been released!

Let's get the value experimenting going again!

you figured out how to have full reflections??!!

Apparently he has! God, so much awesome in a matter of 24 hours, my head's about to explode. My fingers are just typing away code while I'm headbanging to dubstep.

I don't need drugs. Days like these are good enough.

WOW... That is absolutely stellar. Looking forward to what you guys can come up with. Wow.

Hey Guys,

It´s possible edit only the Acessories light?

because i love it the default light on players/uniforms, but acessories, socks are no black...

tatlopuyo mentioned a value that alters the accessories shininess, he may have more to say on that front.

@lagoa..yes its quite possible but u have to manually change the values on the hex editor..coz if you change every value to another one you wont get the best results..here is the the values to change for accessories.. 7B 14 3E C0 00 00 80 3F

do you guys also want the values for the ball?

tatlopuyo, the more info we can gather here, the better. So post the ball parameters as well.

You're saying that it's better if we edit each accessory's lighting separately? How many times do these parameters show up (the accessories ones I mean)? Can they be separated into blocks that make sense and can be changed together?

@lagoa..yes its quite possible but u have to manually change the values on the hex editor..coz if you change every value to another one you wont get the best results..here is the the values to change for accessories.. 7B 14 3E C0 00 00 80 3F

U have any screen about this?

Working on socks? What values i need to change for this (7B 14 3E C0 00 00 80 3F) with a Hex Editor?

Thks for the info!

ill show you an example..its complicated editing the global...im having a hard time..




im still experementing how many (7B 14 3E C0 00 00 80 3F) we need to change..and what part of it needs changing...

Wow!!! Niiice man.... just change the acessories "contrast" ? Not skin or faces?

And white is nice too? Can i help you in some stuff? =)

that will be wonderful if you can help lagoa...


anyways,hex editing the global is more complicated than i thought..i was studying what john doe did on the global last year..and its really complicated..he changes almost every value in the gloss sampler which 2k12 doesnt have..but 2k12 have a fake shadows sampler...and each offsets of it have different values... heres a sample offset where we have to change the values...
the offset is b1b660 and we have to change the values from b1b66b-b1b7a8 and thats just one...theres about 20+ fakeshadowsampler in the global....its hard.spent most of my time yesterday trying to figure out what to do....had some progress but not enough..maybe you guys can figure it out better than me..i have very little knowledge with hex editing.i just got lucky sometimes..by the way ill share the full reflections and the ball offsets next time..my head hurts researching thisl.

ill show you an example..its complicated editing the global...im having a hard time..

Sexy black socks!

my problem with socks is in closeup, they are black, but during gameplay, turns gray....
