best practices for lighting interiors?

[portnicki]

Hi all,

I'm playing around with a simple scene.
I have a room with 3 large windows (other than that, the room is closed in every other side).

I've been trying to lit it only with an HDR environment but the result looks pretty dark. I've had better luck using a "Daylight Environment" with a directional light (I'm in modo here).

I'm pretty surprised as how much hot-pixels I get with already 1000 rays shot into the render (Path tracing). I'm actually wondering if this render will eventually clear up?

I've even put a large blackbody emmiter behind my camera (inside the room) and lit the interior a lil' bit. Thats a way I used to clear the noise in modo renderer. But I do not think it helped by any means.

What am I doing wrong here? How do I get clear interior shots without the ton of hot pixels?
PS. I do not want well lit interior, I;m lookin' more for a very bright highlights & dark shadowy ares look.



this is 1500 rays. Should I just give it an hour or two?

All you need for this is to use GI clamp tool in PT kernel settings. It reduces light paths that are strongly contributing in a scene and hence speed up renders vastly. Test with a value 1 to 10. If you set to 0 you are only left with direct light.

and for better shadows use closer to 1 (rather than 0) path term power. It will reduce speed of rendering but gives better shadows.
