Hi, PROH, thank you for your suggestion, but it's more complicated. I want to passing through ceiling only ambient HDRI light and block sunlight. In your suggested case interior will illuminate by both light sources. Basically, I can't exclude specifically one object from selected light source to not create a shadow. I can exclude illumination in light source's exclude/include list, but not shadow casting.
Hi, romullus, hack was not succeed :) I tried standard omni lights, coronarayswitchmtl, coronalightmlt, even tried your suggestion to use corona light as environment HDRI portal. But not succeed, I got in best case only random light spots.
Funny enough I have manage my goal by simply workaround - remove ceiling, put blind wall near apartment to block only sunlight.
But still It would be great to have an option to disable specific object's shadow casting in particular light source.
