I've been searching the internet for some time to find a simple normalmap generator and mostly found commercial stuff like CrazyBump or bloated programs that do a lot more than is needed for me. Another possibility is a free Photoshop or Fimp plugin. As I don't own Photoshop and am not much of a friend of Gimp I decided to write a generator myself.
Actually it's a rip from a bigger editor I'm working on so don't expect too much.

Do you combine the normalmaps of three different blurr stages? It would probably be nice to have a little more freedom, but I guess the results are already better than those, still too many people are working with. What about maybe some batch functionality? The results may aren´t perfect for each texture then, but I am lazy and have quite a few textures without normalmaps wink

The map is scaled to 1/4 and 1/8 and rescaled again so it's actually bilinear filtering only. Batch functionality should be possible. Maybe I'll implement it but rotating the preview cube is more important right now.

That is great, thank you!

A little bug:
The "generate" process did not stop (the progress bar was complete) and the generate window did not disappear after I clicked the button to create the normal map a second time with a higher "big detail" value.

Do you use the CPU or the GPU?
I started dev such an editor using pp effects wich was indeed quite fast, but then I decided to wait for the engine feature wich allows you to modify a bitmap through a shader directly (instead of the rendering only) since using ppEffects is not so handy tongue

Nevertheless, great work! wink

that's actually a nice idea, Hummel. I'll think about implementing this. Will post a new version than where you can move the cube and the light source
