Object shadows

I’m working on a augmented reality application for mobile devices and I need to cast the shadows of an object. I need that the shadows stands “on air” I mean, there isn’t any plane or somethig like that where the shadow is projected. Anyone knows how can I do that?

Thanks

You need geometry for the shader to process it. I don’t have pro so I don’t know if it works, but you probably can create a plane, child of the object, make it transparent and make sure it still receive shadows.
