My first successful Interior Renders

Amazing Shots
1

Yeah, I feel like these are the first interior renders I feel proud of.
Rendering these shots in Keyshot is hard.
Post-processing done in Krita!

Any feedback on how to improve?

Nice! Don’t see often interiors done with KeyShot but it worked really well! Were there certain things about, for example, the render settings you had to play with to get smooth lighting in the interior?

Think that’s nice for people who also try interiors but in my experience getting enough light everywhere can be quite hard.

They’re lovely images! Great work. I really like the colors and I think they have a very natural feel with the soft light.

Since you asked for feedback.

  1. I think DoF is critical in almost all scenarios in creating some sense of realism.
  2. They’re a bit *too clean. I’d try adding some imperfections if possible on some of the larger surfaces like the flooring (which looks a bit too smooth I think) and the walls.
  3. I’d add some film grain (very, very subtle since nice images won’t be as grain-free as these renderings.
  4. I would actually push for much greater contrast in the lighting. This is of course just personal taste, but if you can really push the brightness of the light outside that window (like 5-10x brighter), and maybe reduce some of the ambient light, I think it would have a more ‘photographic’ feeling.

But once again. I really like your renderings here. But I’d also love to see you take one more pass at them since it wouldn’t take much time and I think the results could be improved! Hope that’s helpful!

Hey, thanks!
I think I have set 32 Ray Bounces and 16 GI Bounces and that’s about it. No Interior Mode.
Outside is a very small, very intense fake sun HDRI I’ve made with neutral colors.
Inside, there is a Spot Light and a Point Light and that’s it.

Oh and I left them to develop for arround 48h over the weekend.

I think the most important step here was the post production. I’ve come to embrace that, for as hard as I try, no render ever comes out looking like a final image from Keyshot. I always run it through some image editor to tweak the curves, occlusion shadows, individual colors of objects, etc…

The living room image has a Threshold layer, with a Gaussian Blur filter and set to Smooth Light blending mode to emulate Bloom, because I forgot to set it up before rendering.
“I’ll fix it in post.” is a real thing and a very time-effective skill to develop.

Thank you for your feedback!

Yeah, I can see it and I’ll try to implement that feedback onto my next interior.
Unfortunately my employer had already shipped the image to their client before I made this post so I won’t get a chance to develop it further.

My employer’s PC is fairly weak (i710400 32GB RAM + GTX 1050Ti Low Profile) so adjusting for imperfections is really tough with all the noise, and the first passes at denoising kill most of the detail. Do you have some advice on working arround these limitations?

Nice! And I think you’re right about POST. I’m an oldie and worked with Photoshop since version 2.5 without layers :wink: and when rendering became a thing I really tried to limit the amount of POST but like you say, it’s pretty save to say it’s always used.

Especially these days where every series/movie you see always have some heavy color grading and/or LUT files used to give a certain atmosphere.

I try to limit it a bit but contrast is always a thing. Or you have to put the curve already in KeyShot which looks nice but having a more linear image to do some POST in Photoshop/Krita/Gimp can be much easier since you’ve more bandwidth to work with.

48 hours is quite a lot of time, but looking at the system specs it makes sense. If I were your employer I would put a simple PC somewhere with a nice 4090 which will reduce the 48 hours to 2 hours for the same result (as long as you use GPU to render). Gives you more time to experiment :slight_smile:

I see!

Sorry, my only advice for working around low PC specs is to upgrade, haha. Let your employer know the most expensive thing is you sitting idle while the computer renders. Maybe you can convince them to upgrade. Your work is nice, so hopefully they appreciate your contributions!
