Photorealistic Kitchen I just finished... with Octane :-D

[charlesp2]

Hello Octaners,

I'm new at Octane but getting better! On Max plugin, 2x 780 3GB, 2000x1250, 1h 10 min @ 12000 samples, DL+Diffuse, 2 bounces (scene didn't need more), speed around 9.1MSamples/sec, using OCtane Daylight system, Octane Lights at windows, and BlackBody Emitters on the ceiling lights and a little bloom.

The result, at least to me, is pretty photorealistic and almost no grain.

I'm happy with it, my client loved it and is giving me the entire house to render, so far Octane is dethroning Vray at my studio we're pretty happy with it.



Comment/crits/ on how to improve / faster rendertimes welcome

Nice work! Yeh, Octane has dethroned Vray at my studio as well. Glad to hear you are liking it!

Some comments and crits, and this is me being nit picky here in an effort to help the most:

1) your hanging lighting above the island looks terrific!
2) the brush on your range and hood is too wide, it seems a little off scale
3) I'd increase the bump, or use a slight displacement on your backsplash tile
4) your island water faucet and stovetop faucet look like different materials -- was this intentional5
5) the radius on the edges of your hood seems a little large -- typically these are made of 18ga SS, which is .048" thick
6) I'd take a look at overexposing your exterior images a little more, this keeps your eye in the kitchen more and would be more realistic
7) the back of the chair seats look a little blown out
8) this is totally personal preference, but I'd make the overhead kitchen lighting warmer, more like halogen instead of a fluorescent. This will give a more inviting feel to the image.

All in all this is looking really good.

As for render speed:

1) with any progressive type of renderer like Octane, Maxwell, etc. it helps GREATLY on interior rendering speed to place some additional lighting behind the camera -- NOT too strong, you don't want to throw off the image with false lighting, just enough to help lightly "fill in" the darkest of areas. This will help the image clear faster.
2) depending on which shots you need, you could also consider leaving the walls behind your camera out, so the model is open. It will clear much faster this way.

I hope this helps! Looking forward to seeing more from you!

Hey there thanks for your awesome tips and attention to detail and your positive comments thanks!

Regarding lighting, the trick you said about placing a light behind the camera, it's already there, I'm learning but you're right that "fill" light helps a lot. Regarding the exterior, yes I'll probably make that cooler. And about the lighting over the kitchen, you're totally right about warming it up.

Also I'm looking into post-processing tutorials to make the images more "magical" but with Octane's built-in bloom and glares, it's hard to think of a way to achieve that. Anyone with tips / tutorial links welcome!

Besides the above comment, what I would say is to turn off the perspective fix. I know this is very popular for architects, but for interiors, it makes things look wonky when the camera is close to them and more unrealistic (you would never be able to take a picture like that in reality).

Other then that, the backsplash looks like it has too much bump and it also looks like you used an image texture for those pipes above the stove. That makes the image look more fake. I would quickly model that or leave it out. The hanging fixtures look great at first, but now I see they are an image that is photoshoped on. The dead give away is that the alpha mask isnt correct. you can see a halo around the image. I can't think of what they are called, but there are some photoshop filters to get rid of that. something to do with "pre-multiply alpha" can usually fix that as well. Don't know how to do it in photoshop though.

Hi kavorka, actually, the lamps are not photoshopped in, they are a picture that the client sent, put into a Plane inside 3dsmax, and given an Opacity map. Thanks about the tip for the perspective fix, will try that out. I made it because my client wanted correct lines in the rendering.

You are correct about the pipes above the image, they are just a texture. But hey, all in all, it looks way more than enough realistic for my client's requirements. . Thanks for the feedback tho, it will help me improve!

ah, in that case, try to check "pre-multiply alpha" in the imager tab. might fix the halo problem.
