Living Room - MR Lighting Study

Here's the update.. Thanks Justin for the help with the GI settings. I think its furniture time. [ATTACH=CONFIG]44532[/ATTACH]

try this: GI: Max sample radius 300mm (I have a hard time with inches :) ) Max no Photons per sample 100 Max Trace Depth 200 Max reflection 100 Max Refractions 100 Average GI photons per light 100 000, increase for more detail. Tick All objects generate GI FG is fine If you have glass geometry in the window set it not to generate GI and Pass through FG, maybe the same with the blinds.

Defiantly better, you got rid of the noise on the walls.

thanks.. I tend to agree. Might have hit it too hard in post, though.

Here are the render settings: I do the DoF and C/A in post so I'll just lighten the opacity of those layers. [ATTACH=CONFIG]44523[/ATTACH]

could be better though, post your render settings The CA or DOF is killing it, leave it off for now. jhv

Defiantly better, you got rid of the noise on the walls.

Here's an update.. I'm using gi/fg and portals. I have my gi mult. at .8 so it contributes less to the scene. Better? worse? .. same? [ATTACH=CONFIG]44519[/ATTACH]

In this case where you dont see strong direct light from the sun, I'd not use a mrsun and sky system. Rather I'd use a large area light just outside the window. Start with the default settings. Seeing that there is a lot of small detail, go with a small photon radius, low samples.Use very high Trace Depth settings, eg Max Depth 300, Max reflect 150 and max refract 150 (this should allow for enough bounces to get into the deep recesses). Leave FG off until you find the right amount of photons and radius to get good, even coverage throughout the scene and a decent amount of lighting detail. Then turn on FG, draft, 0 bounces. Use the interpolation to clean up blotches. For the Light, leave the Photon settings to automatic. Play with the intensity and colour to get the look you want. Exposure control will be very important to get right. jhv

What's an appropriate value? I rarely use GI.

dont be afraid to use photons. it get rid of the blotchies, increase the fg interpolation jhv
