Hey guys,

I've been trying to set up an interior scene in KS7 and I'm having problems with the lighting.
- I'm using 4 panels with an area diffuse light (3 inside the room and one outside behind the window).
- environment is a HDRI
- the room is fully enclosed
- windows are default basic white glass

I've attached some screenshots with the settings as I don't want to share the Bip just yet.
A 3 hour region render with 2000 samples didn't get me any further or should I let it sit for way longer?

Thanks in advance :)

Interesting. It does seem slow indeed. What scale/units is this scene in? And more importantly, what is your machine's CPU specs?

The scene units are centimeters.

I'm working on a Macbook Retina with 8 GB RAM (1600 MHz DDR3), 2,4 GHz Intel Core i5.
Graphics Card is an Intel Iris 1536 MB.

That's your problem... the CPU is an Intel Core i5. Despite having 4 cores, it lacks hyperthreading meaning KeyShot will only see 4 threads. With an i7, you double the thread count and thus performance.

An interior scene on a machine with an i5 chip will take long. Interior scenes are known for taking longer... you could change your area lights to point lights and they'll be a lot faster, but may not offer the exact appearance you're looking for.

Also, the smaller your rendering, the faster it'll go. Best of luck.

Thanks Will!  :)

I think I should avoid doing interior scenes with my current set up from now on.
