In my latest project, i have an object that I have drawn using Adobe Fireworks. The object is "inner beveled" in a manner that gives it a top down but semi-3D look. To pull this off, on side and the bottom is "darker" while the opposite side and top are highlighted. This is very effective until you wish to set the angle of the object.
Is there a way (using a shader) to always illuminate from a constant direction?
Thank you in advance!
