I want to create the appearance of a shape being cut into another shape, kind of like an inner bevel. Please see the house icon in the attached image for the exact look I'm going for. (This image is from http://vectips.com/tutorials/create-a-wood-grain-texture/) I don't care about the wood grain, but rather about the look of the house shape being cut into a block. Can someone explain how to do this or point me to a tutorial?
Thanks very much!
