exporting textures

how do I export my textures in blender to use in other projects.

I dont think you can export them…You probably can apply them to a plane, make the material shadeless, and then render with the camera directly overhead in orthographic mode.

actually, I mean exporting materials.

You can’t. Every renderer has its own material system. The .obj and .fbx formats have some very basic material logging built in, but it’s pretty much limited to color and specularity and isn’t at all useful for modern render engines.

To use materials in other blender projects? You can use the materials by appending them into another scene. File>append

awsome,thanks

Also, while this wasn’t really what you meant anyway, Rich’s first answer was wrong - if you have a UV map set up for your object you can bake textures (including procedural components, dirty vertex colours from vertex paint, ambient occlusion of the model, etc.) to an image.
