Guns Guns Guns

here's an update.
I finished my normalmap yesterday.
for those of you who don't know what it is: a normalmap creates the illusion that there is more geometry than there actually is. by talling the specular where to go (speculars are calculated by the shader using the normals of an object.
it's possible to store the normals of a smooth opbject into textures for a chunky low poly object. this is done by calculating the difference between the chunky low and the smooth high poly, and storing that in a normalmap, which is applies like a texture.

here I've 'baked' the way the blue highpoly looks onto the chunky red and it makes the bottom chunky one look as smooth as the top most!



cheers!
