if i stick a cube in the middle of the stage in swift then it just sits there in the middle of space and does not cast any shadows etc.

if I put the cube directly ontop of a plane then I get nice shadows cast onto the plain.

Is there a way i can get swift 3d to react as if there is a plain there and produce shadows etc. without having to export the plain in the final file?

This is an issue because i want the shadow effects, but need to sit the objects sat on a transparent background created in flash.

I could just remove the plain from the exported file frame by frame but was hoping for a more automated solution.
