I need a little help I actually got this pf track program working pretty well I am now in maya with the tracked data and want to put just a poly cube in the scene...got that but I need it to have shadow that apprear to drop on the table from the real world. I thought that a plane with a surface shader applied would give me just the shadow from the cube, and not render the plane??? didnt work...basically I need a shader to apply to the poly plane that is under the cube so that I can see the shadows from the poly cube, but the plane needs to be invisible. thanks
