Raytraced AO with Baked Lighting?

Hi, does anyone know if it’s possible to get Raytraced AO to show up with static lighting? Or does AO rely entirely on dynamic lights? When I switch the view to the AO buffer, everything looks glorious, but as soon as I switch back to Lit or Lighting Only, all the AO disappears.

Why would you need rtao with baked lighting?

Becuse: what about dynamic objects?

Then you would use stationary lighting.
