Mattn:
the normal map should not include details like the texture - see sitters normalmap from above - or even better, try to understand the tutorial in the artwork wiki article that i linked. normalmaps are just a kind of heightmap (basically). it often help when you flatten the image colors to e.g. 5 or 6 colors (in your image 3 colors would be the best - 2 color for the squares and 1 color for the gap between them) then gaussian blurring might help a little (also depends on the image - convert back to rgba and encode the height in the normalmap.

Well, sitters normal map has a texture, although it is very subtle, because it's just cloth.

And why shouldn't it, does it take more calculation time to apply a complex normal map than it takes to applly a simple normal map? As far as I know it doesn't.

I don't think UFO:AI let's you zoom in far enough that it matters, but it doen't hurt to have the detail either.

I think we might be talking about different things here. I do understand the concept of a normal map, and that of a bump map. I was not aware you could have both in one, that's all.

The normal map I made does not include any texture information. However, it obviously emphasises some of the details that can already be seen in the texture (dirt, scratches, dents). As matter of fact, the normal map was not created from the finished texture, but in parallel.

I have reattached both pictures in a higher resolution below. The normal map _is_ mostly flat apart from some detail of course. As DuKe says: more detail shouldn't hurt.

The alpha channel makes it a bit difficult to see the colour information in the gap between the tiles.

Happy new year everybody.

I had a stab at another texture: wall013. Let me know what you guys think. I'm still learning, so any constructive criticism is most welcome :)

Are normal maps implemented in trunk? Could somebody maybe post a screenshot with the texture in action? I haven't taken a look at compiling the sources yet.

@Mattn: I'm having some trouble uploading the pics. Says the upload folder is full. Could you do the honours again? Thanks!

thanks for the texture - yes - normalmaps are implemented in trunk. but i can't post a screenshot - my notebook is not capable of running the glsl shaders.
