Title: How to render only objects within masks
Post by: John.McWaters on 2022-09-21, 17:07:21

I know there is the 'render only masks' check box under the Scene tab, but is there a way to render only the objects and areas contained in a specific mask as they would be appear in the Beauty image?

Other than manually selecting them and using Render Selected, and manually drawing Regions, no, sorry.

I am not sure if I understand the question. Could you share an example of what you would like to do?
What you are describing sounds like something that could be achieved with the "Render Selected (Pixel Mask)" option in the Scene tab.

I would like to render a scene without a person, then render the scene with the person so I can add it to the image and give it motion blur. If I could just render the person object, I could save time. The plan was to do this is PS. This is an alternative plan I came up with.

"Render Selected (Pixel Mask)" option should allow you to do that. Select your 3D human, enable that option, and render. This will render the beauty pass, but only with the selected object.
