Just looking around some Doom 3 mod sites and I found this brilliant texturing tutorial. It uses Photoshop but I'm sure people here without it will be able to find a way in GIMP or something.

Here's the link

its cool, but i think it is unneccessary unless you are going for the ultimate realism. still a cool technique though.

Seppuku.... you said that this would help me.... but it doesn't really.

I've created a texture from scratch, and I want to know how to convert it into a normal map....

I apologise for being a complete noob.... but it's just who I am

I wrote a normal mapping tutorial for one of the newsletters a few months back. It covers making normal maps from both high poly models and also textures/photographs:

http://www.thegamecreators.com/data/newsletter/newsletter_issue_48.html#6


Remember, you'll need a grayscale version of your texture, the parts you want to be RAISED should be whiter, and the parts you want low or RECESSED should be darker. Generally the more contrast the better. Simply desaturating your image WILL NOT work 99% of the time. Then run your grayscale image thru either the Nvidia Photoshop filter or the free Crazybump program to generate your normal map.
