Rendering Specific Objects with Render Mask and their shadows

[kenia_orellana]

Hello

is it possible to render Specific Objects using the Render Mask and include the shadows within that render?
Example

when i render the sphere as selcted object i get only the object without a shadow

The idea is that i would get that sphere with shadows,

Is that possible?

Setting all other objects as shadow catchers should be of use to you. To get only a specific object's shadow, you would have to disable all other objects' shadow casting, though (no way of separating shadows, I'm afraid). Afterward, compose the rendered object (and its shadows) on any background.
