TEXTURELESS geometry just for shadow casting?

n.drju_6d88cb4c15

So I guess the title explains what I intend to do...

I want some objects rendered in Iray due to its marvelous quality. But then, I would like to paste them into a scene that is going to be rendered in another program.

In order to make the final composition realistic though, I need to have proper, terrain-reliant shadows made in DAZ Studio. Otherwise, the shadows simply use a flat ground as a shadow base which is no good. :(

I actually imported a portion of the terrain from the program I intend to render the rest of the scene in, but I am left with a greyish husk that should not be there.

So the question is - how can you import a portion of the terrain that has no color and is just an invisible geometry that receives shadows? After all, DS does something like this with the default shadow in an epty scene - the ground is invisible but the shadow is.

Help much anticipated... and appreciatied! :)

1. Create or load your shadow catcher and make sure it is selected.
2. Go to Scripts>Utilities in a content pane (DAZ Studio Formats>content directory>Scripts>Utilities in the Content Library, or use a category view) and open Create Advanced IrayNode Properties.
3. In the Parameters pane, under Display, turn on Enable Iray Matte.
