Skylight leaks light into interiors when Global Illumination is disabled

Hi,

I have a scene which uses a standard directional light and a standard skylight.

When used with Lumen i get the nice Global Illumination and we get control of Skylight Leaking via a PostProcess which helps with some of the interior lighting.

For some console platforms we have to disable Global Illumination and as a result the Skylight now floods full strength light into the interiors (in the same way as if LightLeaking was set to 1 - even though its set to 0). The buildings double sided walls dont seem to occlude the skylights lighting.

Is this the expected behaviour? If so, is there a work around please? As currently for the skylight strength to be correct for outside, its too bright for inside.

Thanks,

Leon.
