Thanks!

I ran that rendering on a dual Xeon E5-2680 workstation.
I think I grabbed a screenshot from the realtime window after two hours or so? Not entirely sure.

Of course that translucent lamp shade introduces a rendering time penalty.
I tried different materials for the lamp shade too. Then the image resolves much faster, but you don't get that soft diffusion of light behind the lamp.

E.g. I grabbed these shots after 10  minutes rendering or so.
Nr. 1: highly reflective metal shade
Nr. 2: mimicing of original shade in advanced material type

The scene with metal shade does render very fast!

nice, thanks for those info and sharing new tests!
2 hours for such a simple scene though is a little too much :) but I do understand that there is quite a bit going on computational wise.

Yes, I guess that what I did is computationally very expensive. The light bulb is literally throwing around photons in order for a defined projected light pattern to form. You realy see this as the rendering progresses.
That's why it's so great we'll be able to use IES profiles! Then we won't need to model fixtures and KeyShot doesn't need to churn out a light distribution pattern on the fly. The luminous parameters are right there, served in a text file! 8)

I just did this scene to see if it could be done in KeyShot. And boy, can it be done! ;D
I was actually very surprised when I saw how KeyShot handled the scene so well.
In the past I have used a number of other rendering engines. With all of them rendering a lamp shade without IES would be very tricky. KeyShot by far has the most straightforward approach to make it happen.

Rendered in keyShot 4 Beta - lit with just 2 Area Lights with GI turned on - the HDRI brightness was reduced dramatically, in fact its almost non-existent...

Looking good!

Yes, the local lights are going to do some serious damage... :D

And another pair of lamp shades, now with caustics.

Mech WIP lit with 1 strong Area Light and 10% strength HDRI brightness...

You can now achieve well defined shadows that were extremely difficult if not impossible in KS3

Textured and materialized version to come...

Cheers

Caustic, Area lights and hard shadows. All the things i've been missing in the other version!
KS4 is going to be awesome!

I have been out busy working on other stuff but I was very pleased to see the sneak peak.   Looks very exciting!

Well get on the Beta test team then and crack out some noise free renders...

Those are some impressive renderings Dries! Noise when caustics are involved isn't strange considering the amount of calculations needed. Here's an overnight render and noise is visible in the caustics (my i7 3930K could need some additional help!).

Nice renderings, Dries, Raaden and biomechanic. Keep it up! :)
