multiple shadows using projector

[theuberk]

I'm trying to create multiple shadows using the projector module. It seems however that only one projected can exist at one time. For example, the following code only produces one shadow (proj2):

enviro = viz.add('C:\\Program Files\\WorldViz\\Vizard30\\resources\\tut_ground.wrl')
image1 = viz.add('cars\\carShadow.png')
image2 = viz.add('cars\\carShadow2.png')
proj1 = projector.add(image1)
proj1.translate(0,0,0)
proj1.rotate(0,90,0)
proj1.affect(enviro)
proj1.ortho(2,2)
proj2 = projector.add(image2)
proj2.translate(6,0,0)
proj2.rotate(0,90,0)
proj2.affect(enviro)
proj2.ortho(2,2)

Any help would be greatly appreciated.
