Orthographic SSAO

does anyone know of a method of SSAO that can be used in orthographic camera configurations? I understand that SSAO works by calculating depth – which orthographic essentially eliminates by making everything appear to be on one axis – but is there a way to fake it?

Thanks :slight_smile:

EDIT: One way of doing it I have found is to add a sun lamp that is at the same angle of the camera – set to shadow only. Though this doesn’t affect the ground around objects – only what is behind it. But a shader would be more interesting.
