Is there a way in Poser 5 that you can render the shadow of a tranmaped item and have the shadow look like it came from the tranmaped item? Like a leaf on a tree.

i the mat room you can add such a map to one of the lights( best is to use a spotlight) and you can get effects like shadows from leaves. Think at rundna there where some free mats for such purpose

If you're using the Poser 4 renderer, you have to use a square prop (or some other prop) in place of the ground plane. For some reason, the ground plane doesn't display transmapped shadows with the P4 render engine. This isn't a quirk of Poser 5, either; the same oddity occurs in Poser 4 and Pro Pack.

If you're using the Firefly renderer, it'll cast transmapped shadows properly, even on the ground plane. Make sure that that Transparency_Falloff is set to 0.0.

Let me see if I get this straight Little Dragon. If I use a flat square prop for the ground plane it should work? That is not a problem.:) I do however have a question about Firefly. What would the setting be for such an effect. I don't use Firefly because I am not sure what to turn off and what to turn on.:) Can you help with that? If you haven't guessed I confuse easily. :)

The only setting you need concern yourself with in Firefly's Render Options is Cast Shadows. Enable it, and you're ready to go. Assuming you've installed the latest service release, Firefly will properly render transmapped shadows, whether the lights use shadow maps or raytracing. What you have to watch out for are your material settings. Again, when you apply your transmap to a material, make certain Transparency_Falloff=0.0. If the transparent parts aren't truly transparent, neither are the shadows.
