I’ve just posted this on Blend Swap:
It’s a test of Cycles Blender 2.62 Path Tracing of an interior Archviz scene, if the settings or anything that you are interested in, please feel free to check it out. There is a lengthy PDF included which explains most of the things in the blend.
For those that can’t wait to read the lovely prepared PDF, here’s a brief summary of the set up:
Lighting in the scene we have:
1 x Sun lamp
Internal Sky Background Texture
3 x Mesh Emitters for the visible windows (Camera Ray Visibility off)
1 x Mesh Emitter for the simple window behind the camera to add a bit of extra bounced light(Shadows off)
1 x Background Street Image set as an Emitter/Shadeless node material (lightened to appear over exposed as it would be if the shot was taken indoors with a camera).
Note: I avoided Area Lights as they cause too many Fireflies, it’s amazing to see how bad they can be compared to Mesh Emitters. Area Lights created hundreds of them, Mesh Emitters created none.
To keep the speed up without loosing too much quality I set Cycles Integrators to these settings:
Samples - Render: 6000 - Preview: 20
Bounces - Max : 8 - Min 8
Transparency - Max 8 - Min 8
Light Paths - Diffuse 2 - Glossy 2 - Transmission 2
Renders in around 20 minutes on GPU, not tested on CPU.
