Hi All,
Well I'm diving into my first interior render that is not a vehicle....lol I thought I would show my progress of this.
I see a lot of people asking about Keyshot and interior renders. So I thought I would take a crack at it.
The room has four walls a ceiling and floor. All parts are on. The only thing that is lighting up to bathroom is the light going through the windows and the ies lights I have used in the ceiling fixture.
I decided I would light the scene first. Once I had the lighting the way I wanted it that's when I would start materializing the room. Make the material to the lighting not the lighting to the materials.
Here is my first lighting test.
I really like how I was able to get the shadows soft from the windows and much sharper off the stool.
I have not picked any angle yet. Again this is stage 1. (Lighting/Mood)
Comments suggestions are always welcome.
Tim
This is looking good Tim, nice clean models make it a good scene. I look forward to seeing more, eggshell latex paints look good on interior shots. I think your next step should be to just setup your reflective surfaces and get the GI bouncing around to see how it looks. I can't tell your cameras focal length setting either, but from my old photography days we always used 18 to 28 mm lenses for interiors to make them look larger rooms.
Martin
I will keep my eyes for this topic, as I always fail at rendering interior with KS.
Keep updating, Tim :D
Bronson
Great, looking forward to see more
This is looking good Tim. Good point about lighting the scene first (more or less) then materialising to the lighting. It took me a lot of too'ing and frowing to realise that. I'll be watching this thread like a hawk to see how you overcome a few 'challenges' i have experienced trying to do 'closed' interiors. Im also super curious to see what this 'indirect bounces' slider is all about... i'v got high hopes. Luxion knows how to do very convincing GI for interiors - iv seen it in their 'Visualizer' product for Velux. As far as camera lens widths, I disagree with Martin, a bit. The human eye is equivalent to 42mm or so. I think the nicest interior shots are 'intimate' shots around the 40mm range. Obviously, if you need to get more of a small room into the shot, then Martin is spot on, just be wary of overly wide lens shots - they end up looking like real estate agents photos.
My 'keyshot wet dream' is to model an interior I'm happy with, light it and materialise it, set where I want my camera, then output an HDRI, and a few backplates to be used 'as normal' in keyshot.
Looking forwards to seeing how you get on... good luck
Ed
This is interesting - I've got some interor shots coming up for an architectural gig. I've just been playing around with the Velux software, never seen it before.. and I have to say the results are pretty impressive (thanks Edwardo!)
Tim, how are you doing the lighting? - are you using the daytime sim in KS? Or are you bouncing light in? (via white plane or whatever for indirect lighting?).. looks good so far man.
Thanks everyone for the comments and tips. I will look into all of them.
I made the windows a diffuse area light. I just needed alittle more fill light. The thing with IES lights is not to have them too bright. Your HDR still has to do most of the lighting of the scene. If you turn off your dome and your scene does not change then your relying on the IES lights to much. Thats when you start to loose the realisium of the scene. Also sparkles start to happen when you render....rrrrrr Yes I used Keyshot 5 HDR editor for creating the early/late day light.
I'm excited to work on this. I hope I have some time this weekend.
Tim
This is interesting indeed. I'm looking forward to see where you will take this!
I gotcha, thanks for the info.. your render looks super-clean, how many ray bounces/indirect bounces? ... and apologies for all the questions, but are you using the realtime or the actual renderer? If the latter, what are your settings?
Sorry, It's just useful to pick the brains of someone who knows what they're doing ;D

OK for 95 % of my rendering I use 16 sample, 16 bounces, default for everything else.
I crank up the sample on the materials I create. Not in the render settings. For example almost all my materials I increase sample to 32.
I always raytrace my images very rarely will I do a realtime render.
I will have to do a video of how I set things up.
Tim
Cheers Tim!
A video would be most helpful :)
Here is the first of many images of this interior.
Tim
Cha-ching. That's some great work Tim. Looking forward to that setup video when you have time.
Thanks Guys !
Here is another version.
My next step will work out what to show outside.
Tim
Hey Tim, that looks really good . I assume that adding some of the more shiny materials lightened the room...because of light being bounced about? Did you compensate by lowering the amount of emitted light on your area light diffuse? What did you have it set at?
Looks great :)
From another angle.
Enjoy
Tim
Succulent.
I agree, we need to see the scene setup! :)
One note:
The corners of the room look pretty dark. Did you try increasing indirect bounces? Setting a value of 3-4 should dramatically brighten up those dark areas.
Dries
Nah, it looks fine! :D I think it's important to have a balance of light and shadow... thats just like, my opinion man.
These are great!! Are these straight out of Keyshot or have they've gone through some post?
Yes, looking real nice Tim. 8)
Thanks everyone !
Here are some before and after samples. As you will see I did not do much post work. Only to open and soften it up some.
Tim
Excellent results Tim, prefer the versions with painted walls but they all look great.
Martin
The only thing that bugs me is the depth of the grooves between the floor-tiles ... they make the floor look out of scale to me.
Fcourse; other than that ... awesomeness all over.
You running these through Lightroom?
they look nice coming from KS! But the distortion is really bad, ks cameras are not good for that, so you may try to revert the distortion in post. Lightroom may give you a nice helping hand on that, if you fake him telling you are using a real lens and use a preset value!
The overall lighting and GI looks great, much better than I expected... and not even a single light 'speckle' anywhere! I agree with Briex that the distortion is a bit much. V-raay has a setting for straightening up the distortion whilst using a wide lens width (forget what its called or the terminology used). This is why i prefer sticking to the 40mm mark, or thereabouts - shots just look more natural. I might be missing something, and I'm sure there are exceptions to the rule, but are all interior shots not basically mimicking what we would see from our own eyes?
great stuff! Looking forward to seeing your method of comping in the 'outside world' at the window
ed
Tim was nice enough to share the scene with me.
Here's my version so far.
I hope it's OK if I post here, Tim?
Dries

Looking good buddy !
Thanks for sharing. I understand what your talking about with the contrast. I think that is one of those preference kind of thing.
Since this is a closed interior it's very hard to get a 40mm camera going. When I do either I'm in a wall or it crops way too much of the scene.
I am working a new image I think I have fixed most of the distortion of the camera. I had to turn off a wall so I could back up a bit.
Stay tune
Tim
I think to make interior rendering work really well in KeyShot there needs to be control over lens shift, to correct perspective distortion on verticals.

QuoteI think to make interior rendering work really well in KeyShot there needs to be control over lens shift, to correct perspective distortion on verticals.
+1 from me on that request
Martin
OK so here a new image. I used a wider lens to get the verticals right.
I also decided to color the walls a little bit.
That's a much better result Tim :)

This is an amazing Tim, you don't know how much this is a good help for all users, especially me, i've learned a lot here.
And I would like to thank all whom posted here because this was very interesting.
Thank you ! Glad this has helped you.
My door is always open if you have questions or need help.
I love working on interiors. So much fun. I have the bug. Automotive during the day. Interior Design at night....lol
I'm working on a Kitchen scene right now. Stay tune.
Tim
Looks great Tim. I was just thinking (to get around some GI problems KS still has) would it be worth outputting 3 or more shots of varying exposure (bracketing) and comping them together in photoshop or other HDR making software? Having said that, your lighting looks pretty dam good [corners are possibly a touch dark for my money]
Ed
great job my compliments
