Shading on a logo
Hello. I've been "volunteered" to recreate this logo for a company that cannot find their vector original. I have the shaped, and have been playing around with gradients and masks and 3D, but can't figure out how to add the shading. It's not just one-sided shading as there is a slight shade around additional edges. Since it's a logo, I have to be precise about it. Anyone? It will be used on very large displays, so I really don't want to go with raster.
