modding nba2k9 sharing knowledges

[deepinto]

we could put together everybody's knowledge about how to mod nba2k9. For everyone expecting to be more efficient with a few answers.

[deepinto]

Here are the 4 textile types with there corresponding colors that we can find on a texture correspondance map :




All the 3 colors are pure red (255;0;0) green (0;255;0) and blue (0;0;255)

Correct me if I am wrong :p

2 exemples

raptors 2008 textile top

here are some cleaned DXT5nm nomral map textures :

Alpha is at 50% (seems to be the ideal amout)

DXT5nm nomral map : jersey : shorts




DXT5nm nomral map : jersey : top : round collar





DXT5nm nomral map : jersey : top : V collar (Lakers)




PSD settings I use :

When bumping up (eg Prinical logo and nba logo)



When bumping down (textile reason, not very important), just change the setting to the down radio button

And here is a cleaned crowd color map :

I saw this map once. Then it can be moddified.

Dafont is a good database where we can find similar (not exact) fonts found on jerseys.

I use as many vector as I can. All my logos are *.ai files imported in photoshop. I first start surching on websites (eg webchantier) for brands logo, associations and countries. Didn't have to find Nba logos yet. (eg : the fiba logo that I had to work on)

Nice work deepinto, can you save these as .IFF? I'm guessing not, but is there a plugin for photoshop that will let you?

I checked and photoshop can't open the nba2k9 .iff files despite the use of the .iff plugin.

how to edit colour of accessories?

find the right map with texmod and change the design a bit or totally. Then reload it thanks to texmod again.

sorry....new files uploaded

Ok, then insteed of doing the job. If you are using photoshop, i ll try to teach you. On the top right of the picture for the bump maps setting I posted, is an area called opacity. Keep it in mind. Next, if you have several layers, select one that is visible and press CTRL+ALT+MAJ+E to create a copy of what's visible on a new layer. That will make the job easier to change the document opacity to 50%.

[pernos76]

i try your tutorial but the problem isn't solved (

i try to make the phila retro jersey...but the text mod don't see the bump image .png.....and the picture is orrible white...

can you make for me the bump image and upload? please deepinto help me...i use the photoshop for the fist time.

[Billy King]

if you are exporting transparent files, make sure you change your export settings to .tga and when you save them, it's easier to only include a single layer. that will prevent the image from saving with full opacity.

[pernos76]

thank you billy king, notthing to do
this job is not possible for me (( desperation...

if you want i give you my .png white philadelphia home retro yersey and socks and you create the complete jersey
and after i post in the forum the jersey...if you want: i'ts ok?

You don't need to edit the "bump image."(It is actually called a normal map) The one NBA 2K uses is perfectly fine and there is no need to mod it unless you are highly skilled in the area of normal mapping. So, recreate your patch without touching the bump/normal(the green one with the jersey folds) map, and you can add those fine details to the image that contains the logo. Nobody zooms in that close anyways. You can use the green image as a guide on where to place the details since the jerseys color map is pretty flat.

[deepinto]

I dont want to argue on this but

this type of 3 colors map is a normal map



Imo the green one (even green and not black and white) is closer to a bump map because it does not actually displace the vertexes. It s more about painting a fake volume on the mesh. It can also be a displacement map, I did not check but I don't think so because what is particular with bump maps is that the volume effect disapear when looking from the side.

That's right. You don't need that much to work on that map if you don't know how to do it. But you will get kind of a ghost shape of the modded jersey. And if you use a cleaned green map a 100% opacity you will have some aberation around the top of the jersey.

Anyway sorry to contradict,

[Patr1ck]

Not trying to be a dick, because I know what you said is correct, so I did a search and found out why some of the normal maps in 2K9 are only green.

Code: Select all

DXT5nm Compression

DXT5nm is the same file format as DXT5 except before compression the red channel is moved into the alpha channel, the green channel is left as-is, and the red and blue channels are blanked with the same solid color. This re-arranging of the color channels is often called swizzling.

The Green and Alpha channels are used because in the DXT format they are compressed using somewhat higher bit depths than the Red and Blue channels. Red and Blue have to be filled with the same solid color because DXT uses a compression system that compares differences between the three color channels. If you try to store some kind of texture in Red and/or Blue (specular power, height map, etc.) then the compressor will create more compression artifacts because it has to compare all three channels.

Rewarding piece of information. Thank you.

Deepinto the jerseys and shorts you've posted - can they be used as a base for editing? I know a little bit to be dangerous, sorry, but was wanting to have a go myself.
