How do I deactivate SSAO on certain mesh?

I need to deactivate SSAO on my landscape grass for performance reasons, and I would like to keep it active on other bigger meshes.
How do I do that?

Hey Loxli,

So, in it’s name Screen Space it implied an entire Screen is utilized in the calculation of This AO pass.

SSAO is an all or nothing function.

I will link to our wiki where Distance Field AO is explained.

By default Distance Field is not switched on. There are some steps to do so.
They are in the documentation linked above.

Thanks,
