I just spent a full hour to send you a PM and then this ****ing forum decides to log me out... I did a detailed tutorial for mipmaps, spec/bumb mapping etc... Press send: "you re not logged in" i sure was and never logged out...Not your fault but here's the links...
Read this from start to the specular, forget the examples and height map section: http://www.modwiki.net/wiki/Texturing#Material_shaders You can find better examples from google image but the concept is the same.
You need normalmap filter: http://developer.nvidia.com/nvidia-texture-tools-adobe-photoshop
Mipmaps:
http://en.wikipedia.org/wiki/Mipmap
I'm sorry but i really can't be bothered to write everything again, at least if i get logged out now, the text is still in the cache, unlike in the PM system here... What i basically tried to say in the PM that mipmapping is more important in racing games as we are constantly looking at objects that are far away and all of them gradually comes closer with some going from kilometers to inches, something that no other gametype does...And mipmaps increase BOTH performance and quality, mipmap bias defines when the GPU switches from different versions, too high and they become blurry, too low and they begin to shimmer. Most materials use small negative bias. That's it, now i grab a smoke and breathe normally for few minutes..
