Normal Maps: That Green Jersey Texture

Greetings of mana and peace from the heavens. This is Lean of the NLSC Team and today I am going to explain how I do the green texture for NBA 2K11.

This green texture serves as a bump map for the jerseys and becomes more visible if the global lighting file is modified.

Also, the green textures are present since NBA 2K-Who-Knows-When but when 2K9 came out on the PC, these textures are already there and was used again in succeeding games thereon.

I will provide a blank green texture which I got from NBA 2K9.





Let's get on with the tutorial using the new Washington Wizards jerseys:

Editing the Green Texture


Drag the logos and wordmarks onto the green texture.




I have my layers listed as seen on this screenshot:




Press CTRL and left-click the layer thumbnail of your logo or wordmark, in this case the nba logo layer.



You'll have a selection that looks like this:




I created two new layers as the selection is still active. One layer is filled with a bright green 00c700:



and the second one filled with 023700:




With the selection still active, nudge the selection a few pixels to the top and to the left...



...and hit Delete.



Do the same on the layer with the bright green.






Press CTRL + left-click again on the thumbnail of your logo, create a new layer under the two green layers you created and fill it with green (#008001)



Do the same on other logos on your jersey and you should come up with something like this:

Saving the File


From the previous step, go to the Channels tab and CTRL + left-click the Green channel:



Your selection will look like this:



Create a new layer, and fill it with green. Copy all of that layer, and paste it onto a new document. Your image should look like this:




Save the file as a PNG and import in onto your game.


This is how it looks like in-game:

I hope this helps.

Thanks man

I didn't know it was this simple. Thanks man

I didn't get the last part..

"Create a new layer, and fill it with green. Copy all of that layer, and paste it onto a new document."

He uses the IFF editor so if you use the IFF editor you have to do that... If you use modtool, you don't have to do that, just save it as dds.

now I get it.. thanks mythbuster!
