If you could render an object invisible using optical camouflage, would it still cast a shadow?

I was playing Metal Gear Solid 4 last night and was driving around the MKIII robot with the stealth engaged, when I noticed that the robot was still casting a shadow on the ground. This got me thinking, if you COULD make an object invisible, would it still cast a shadow? I mean, there is still an object there. Assuming the camo is dependent on displaying whats on the other side, not bending light, wouldn't there still be a space where the light isn't passing through the object itself?

In your description of how this particular invisibility works, something like a display mesh that identifies its surroundings and projects light as though it were passing through the object, it's entirely possible that the maximum amount of light the mesh is able to output wouldn't equal the light reaching us from the sun.  Such an object would have a shadow, though that shadow would likely be less dark than an object without the invisibility mesh (whatever amount of light the mesh was able to produce would lighten the shadow some).  There could even be multiple shadows if there were multiple light sources that exceed the mesh's light output (very bright spotlights, etc).
