Rendering an enclosed interior, how do I use HDRI lighting? (CYCLES)

Support Lighting and Rendering

I have artificial lights, but because it is an interior with no windows the HDRI is outside the environment and not contributing, is there something I can enable for its lighting contribution?

I’m not sure why you’d want HDRI lighting for an interior scene with no windows. You can remove the ability for the walls to block the light, but I think you’ll end up with a very unrealistic result

Curious to see this when you’re done

Cheers, will give that a go. Although I just realised / figured out that I’d failed to disable a volume with scatter in the render view which was causing illumination issues and the HDRI now works as it should! Thanks, again.

@Jakebane I tried the shadow ray visibility on various surfaces, you are right, its not a great look! Unfortunately can’t share for confidentiality reasons but thanks for your help nonetheless.

Architecture Topics YouTube channel is very informative for this sort of thing.
One he’s just done, a bathroom, has no windows / door openings. He’s not using an HDRI, but using IES lights as the main light source, then area lights with their “cast shadow” and “multiple importance” turned off, and glossy ray visibility turned off, they provide fill.
This is the video: https://www.youtube.com/watch?v=zctNvwzhgcE

Dunno if that helps you at all.
