Rendering only the shadow of objects.

Good Day!

Once upon a time, I could render a scene on 3dlight, but make it so that some objects are not rendered, but only their shadows. For example on this screenshot instead of table and chairs only their shadow. Can I do this on iray?

    You can't unfortunately. I suspect I know why you want to do this (game dev?) but shadows in iray are a natural result of raytracing and not something calculated separately which can be isolated as it is in 3DL. If I'm right and you're using a game engine, you can export the table and chairs and bake their shadows into a texture map (Unreal and Unity will do this) but if you're just wanting it in 2D then you're out of luck I'm afraid.

    Photoshop time.
