Just as the topic says, I'd like to know how to create normal maps for the skins I make in HL2. Say, I make a new skin for the combine cop, and I wanna make parts of it pop out. So, I go to create a normal map(which I mostly know how to do), by getting the metrocop_normal.vtf Fragger made, using Gaussian blur 100 so it's all one color, and I paste it, desaturate, set to overlay, emboss height 1 amount 500. I'd like to know how to properly make one though.

Do you know how to create height maps? If not, cheat. Take the diffuse texture (the original color skin) and desaturate it. Then use the normal map filter on it. For custom normal maps like my elite, you need to know how height maps work. Basically, they're black and white images where white represents the highest elevation and black the lowest.

Sadly, I don't know how to make a height map. I do know what each shade stands for! White=highest grey=medium black=flat Am I right?

Yes. The secret is to learn how to think in 3d. To test your height maps, create an image in Photoshop and fill it with 50% grey, create your height map as an alpha channel and apply the lighting efects filter using alpha 1 as the channel and checking "white is high".
