How to stop indoor areas being affected by skybox

Hi everyone, I’m using the URP and can’t find any way to stop completely closed off indoor areas being affected by lighting from the skybox. I’ve enabled light layers but there’s no light layer option in the environment tab of the lighting window. If I was using HDRP I’d make a new sky and fog volume and override the skybox but that doesn’t seem to be an option with URP.

If anyone has an idea how to achieve unlit (by the environment map) indoor areas, I would be most grateful. Thanks!

Hi, you may try adding reflection probe(s) to indoor areas.

Skybox lighting is like a “global baked reflection probe” in URP and it will be replaced by other reflection probes (if exist).

Or you can go to Lighting panel and reduce the Intensity Multiplier to 0 (and generate lighting):

But this will also affect outdoor areas
