exporting from blender to unity

ok i have a few question about blender. I shouldn’t be asking here but blender site never seem to be up. I unwrap the cube in blender, edited in photoshop, renderer in blender and it looks great. when i export to unity, only the cube and its green color that i apply in blender got export. where is the texture or material that i edited in photoshop? would someone help? my other question is what you render in blender is that the object that get export?
