Shadow on invisible object?

Michal P.

I am using HDRI for background (Draw Dome = On, Environment Map). Objects cast shadow on the ground. Now imagine dome where is building. Objects in scene should cast shadows also on the wall.

Is there any way to cast shadows also on the walls? My idea was to create invisible wall in the scene which would recive only the shadow. Is is possible? How? Or any other trick?

Yes, you need to use the Create Advanced Iray Node Proeprties script (Scripts>Utilities in the Content Library pane under your Daz Studio Formats cotnainer), then turn on Iray Matte in the Parameters pane.
