Well once upon a time you could use crazy bump to do all normal/specular/etc maps for textures but that's had its format changed and now you need to actually pay for it to use it![]()
After compiling the textures, here's how it looks in-game:
![]()
EDIT:
So, I revised the texture a little, following the advice given in comments on this thread; mostly rounding off the normal map edges, and adding some brush strokes:
![]()
And if anyone's interested, the PSD is available (7zipped, 18MB).
If you've got any questions about the details of a particular step, please ask.
How did you round off the Normal map?
How did you keep the edges detailed?![]()
