3d frame composition

Is there any way to render only the bottom 3/4 of an image?

My client is specific that he wants vertical surfaces to not be angled/distorted.

This means the camera target has to be at the same height as the camera.

I end up with an image that has a lot of ceiling in it that I have to crop off. It wastes render time.

See attached for desired render area.

Any ideas?

I believe what you’re looking for is called 2-point perspective, and it’s an option in your Viewport Properties. Whether your renderer supports it may be another matter.

Depending on the render engine, the lens shift option will shift the active view area.

Here is more on 2-Point Perspecitve in another recent tread.
