Just playing with a classic interior rendering test scene.
Dries
outch!!!
only hdri? outside?
Antoine, for lighting I used:
Completely black HDRI with a tiny (radius '2') very bright pin light. This is the sun.
I then put area lights in front of the windows to simulate sky lighting.
This is using KeyShot 4.3.
Dries
thank you Dries, :))
And the scene come from??

Can't remember. Thought I grabbed it from the modo forums as an LXO scene and then converted it to OBJ...
Anyway, I attached a ksp in case you want to give it a go.

Thnx for sharing this .. I did take a close look but I can't find no gold-fish in those pendant aquariums ... ;)
Here's a realtime screenshot after 1 hour rendering on a dual Xeon E5-2680 (32 logical cores).
Pretty decent I'd say. :)
Dries
Can I ask a silly question? Why bother with the "Completely black HDRI with a tiny (radius '2') very bright pin light. This is the sun" ?
What does this add if it is a closed room with lights on windows?
Thanks Dries
Here's another more resolved shot.

There's no such thing as silly questions, only silly answers. So let's hope my answer isn't silly. ;D
If you use either the area lights or pin light HDRI on its own, the image doesn't look very natural.
With only the area lights active, you only get ambient light (sky). The image feels like there is no direct sun light at all.
With only the pin light HDRI active, you only get harsh light and shadows (sun). The image feels like the sky is pitch black (like in outer space).
I hope attached images help in explaining.
You still have to eyeball and tweak the brightness/color of the sun/sky, but you can get pretty decent results.

Hi rfollette,
Any interior image tends to be 'shot' on a sunny, appealing day and thus have fairly hard shadows - it makes for a much nicer, more dramatic shot. The pin light Dries spoke of provides those hard shadows. If that was the only lighting it would be too harsh with a very high contrast. Adding area lights just outside the windows provides an ambient light to soften the image (and as dries said simulates 'sky light', a more diffuse light caused by cloud cover etc). The two work together to create a more natural feel. Perhaps if Dries is feeling generous he could post an image of the scene with only the HDR, then one with only the area light - I'm pretty sure you would understand the setup if you saw the difference of each image.
I don't get much call for interior shots, but never the less I'd quite like to put together a tutorial someday when I get the time ( I say 'tutorial' but really just mean share my results from some experimenting. I'm seeing more and more interest from keyshot users regarding interiors, so I'm hoping some functionality is added in the near future to cater for these users.... but of course retaining key shots intuitive interface. I have a dream... and that dream is to live in a world free of v-Ray (and proE for that matter)
Ed
Sorry, just realised that Dries has answered that (and more eloquently tham me).
Ps. Nice one Dries, these are nice shots, and help push keyshot interiors forwards. Your scene is just missing one thing.... me, being kept back in detention doing my lines on the blackboard ala Bart Simpson.
Thank you both for your detailed replies.

I was just thinking of doing a interior shot. Getting tired of hearing Keyshot can't do interiors. I was just looking for one to do..
Dries,
This looks very nice has a nice mood. Replace the windows with some scenery in PS and this would be a home run in my book.
Thanks for sharing.
It's a keeper

I totally agree about breaking the rut with some interior work. I did my design for a live/work compound in Santa Fe, New Mexico, and it taught me more that I would have guessed, plus it was a blast! Very different thought processes in play.
BTW, we just sold our home/studio near San Diego and are packing now for our move back to Santa Fe. But we're not going to build our compound there.

I would like to see this interior scene lit with only IES. Pure black HDR and then just IES to see how KeyShot copes and your render times.

A close to, but not exactly the same, classroom can be obtained here along with some other nice interior scenes... for free!: http://www.idst-render.com/scenes.html
It could be great fun with a KeyShot interior challenge, don't you think?
Here's a realtime screenshot (with some PS adjustments) after 1.5 hours of rendering.
After 20 minutes into rendering, the quality of the light didn't change much. Additional rendering helped to get rid of most noise, though.
Lighting consists of:
*area light for the fluorescent tube lamps (all lamps are one part)
*10 x IES light for ceiling pendant lamps
*10 x emissives for ceiling pendant lamps glow
Dries
These are really cool, Dries - Thanks for sharing!
Trying some 'light layer' techniques again.
PSD file used for compositing can be grabbed here (https://drive.google.com/file/d/0Bw6BI0tv_sN8MHJhalF2RWlmQlE/edit?usp=sharing).
Dries
Looks good, i like the second one with the all black HDR - Looks pretty good. How does the render time compare to non IES lighting ?
Martin
GREAT shots Dries. Love this scene.
amazing work and impressive shots ! Thanks for sharing your ksp files :)
Thanks, guys!

Adding some life through textures.
Single shot KeyShot realtime render with some vignetting and adjustment layers added in Photoshop. I also put some KeyShot logos on the board (wallpaper *wink* ;)).
Second image is render without editing.

+1 for the contest ! It will melt our micro-processors but for the good reason ;)

Not sure I could do better shot ;) I'm working on aircraft interior and having your scene and light strategy help me to make a better good looking interior shot. I'll post it later on this topic if I can render it (even if I have 16 core processor it wayyyyyyy long to render :)
Credit for this scene come from??..
Pff,i just asked (maybe on wrong way) credit about this scene come from,for to know where to get and see!
Did u read some accuse about false or bad thing from me to you here on this thread or in some post??no!
So what is your problem guy?so be quiet!!and for your info..i'm not the guy about fb comment.
i'm bored too to get this kind of answer on here..there was an other user here that answered like u,and i tell u the same thing that i i told him..thanks for your answer ..i will never ask you nothing on here..
god
Blimey talk about over reacting, although I don't post here much I'm always viewing and Slater your posting style reminds me of 'tsunami'.
Incredible work, I wouldn't even know where to start in creating something like this!
Another night version of this scene. With intense Sodium-vapor lamp lighting. :D
Dries
Somehow I thought a Dino or two would look cool in this shot. ;D
Dries
Interesting results Dries.
Martin
Here's one with another color scheme.
Sort of 3D-ish. ;)
Dries
Here is my test using your technique... the render set was done on 7hours realtime rendering (8cores laptop) but the result is really bad. We have a good feeling but lacks of smoothness and definition.. don't know how to manage it correctly.
Do you have any specific value you use for your scene ? Or specific options marked ?.
Thanks again for sharing your knowledge !
Are you able to share that scene?
PM me if you are...
Also, are you running 4.2 or 4.3 RC?
Physical lights are much faster in 4.3.
Dries
Thanks Dries ! I will ...
I'm using 4.2 right now. Can't wait to see the progress made in KS 4.3 for the lights :)
