How To: Make bump maps in SoC

This is something that keeps popping up lately so I figured I would give people a very straightforward way to making bump maps.

What you will need:

Paint.net
Photoshop
nvidia DDS plugin for photoshop

1. Open normal texture in Photoshop
2. Filter > NVIDIA Tools > Normal Map Filter
3. Height Generation: 9x9, Height Source: Average RGB, 3D View: Animate Light, Alpha Field: 1.0. Click OK.
4. Save texture as DXT5NM
5. Open texture in Paint.net
6. Adjustments > Invert Colours
7. Save texture as texturename_bump#
8. Adjustments > Levels, deselct Red & Blue channels, move slider all the way to the top
9. Select Blue channel, input 0.55 into Output Gamma field
10. Adjustments > Hue / Saturation, increase saturation to 155
11. Save texture as texturename_bump in DXT5

Done.

Its really that easy. Do note all of those steps you can do in Photoshop but I've found it faster to use paint.net for some of the steps as its a lot faster at saving DDS files than the nvidia plugin is.
