View Full Version : What's a shadow caster?

05-31-2009, 07:10 PM
I see in the 4.0 previews that there is a shadow caster, (or is it shadow catcher) usually assigned to a ground plane or floor. What's the purpose of this? Doesn't a floor normally pick up the shadow of an object once a light shines on it?

I hope i explain this properly.

Letīs assume you like to integrate a 3D model into a photographic background like shown in the car example. If you would render this scene without a shadow catcher object the shadow would simply not be shown there (at the proper perspective position in the photo) at all.

Hope this makes sense.

This tutorial is for Cinema 4d but it is a good visual explanation of what the feature will do.

Thanks, that makes sense. The demo I saw online was using a environment as the shadow catcher. The ability to make your own 3d environments and save them an exr looks very cool in 4.0.
