Hi,
to add some details to this thread.
- SSAO is ‘rendered’ in screen space, but isn’t ‘applied’ as a post-process. Each material samples the SSAO buffer.
_SCREEN_SPACE_OCCLUSIONis a Global (Overridable) Keyword. As explained in this other post, it cannot be locally disabled when globally enabled.
As a work around, you may use a RenderObjects feature to achieve the expected result, as explained in this other thread.
