# Render between outdoor and indoor

I've some experience with Blender (and previously 3DS Max), but I only do something with this once every year.

I have a scene where I want to render somethings outside and other inside, but I am having trouble with the amount of light that I have inside of the building. I know that our eyes can adjust to the light around, and I was hoping that I had a property for the camera to do that instead of tweek HDR sky.

Is the Exposure settings on Scene property or there exists a better way ?

Real World

Outside - Exposure (0)

Inside - Exposure (0)

Inside - Exposure (3.0)

For my lightning settings (Render) I have:

Clamp direct (2.0) Clamp indirect (0.0) Light Sampling Thr (1.0)

I've notice that the noise reduces if I rise Clamp indirect., but also I lose a little bit of direct light. (Exposure: 3.0)

What should be the next step to have better inside light and less noise on render ?

Thanks.

EDIT: End up using Portal Light and increase the samples in the scene property. It doesn't have so much noise. But I need to bump both HDR strength and Exposure to 4.

• You can adjust scene exposure, but it is probably easier to just set up two separate scenes with linked objects, and create an adequate lighting system for each – Duarte Farrajota Ramos Nov 13 '18 at 14:16
• you could try using light portals. – Virgil Sisoe Nov 13 '18 at 16:56
• @VirgilSisoe, thanks. That might be one possible solution. youtube.com/watch?v=1LjLyTBbl6s – David Magalhães Nov 13 '18 at 17:16
