House with one wall

@Rich-O-Brien said in House with one wall:

For some reason I am drawn to the material. So much so I ended up look for real world interior shots. My first thought was some type of galvanised steel.

if you mean the low wall at the right of the stair actually should be an enameled wall. The stairs are concrete and those little strips at the end of the steps should be some kind of silicon I guess.
It was not easy at all to manage the lighting in those two shots with the stairs though.

@Rich-O-Brien said in House with one wall:

You actually mimicked camera positions of photographs!

Indeed, just as I wrote.
if you have some good images to look at its very useful trying to reproduce them In order to tune lighting and materials. You can then, if you like, try some different shots.
The main problem of those nice images is that they are clearly post-produced so non so easy to understand how real things are.

If you jump between real world shots and your renders its nuts!

Also this was maybe the first time that I started by founding a good post-pro process first and then, after, by tuning everything (materials, lighting etc.) in order to accomplish that.

Thanks.

I love it, as usual excellent rendering. A lot of us struggle with photorealism in our own renders but I guess it's a gradual process.

Almost as if, as soon as they were built, they were already an abandoned ruin.

Yes, abandoned by the builders first.

@nickchun Thanks.

"Yes, abandoned by the builders first."
Do you mean that the house seems unfinished? If so I agree with you.
After all this is part of the charm of spaces like those.

"A lot of us struggle with photorealism in our own renders but I guess it's a gradual process."
Indeed. What we need to understand is that before the "how" there is the "what".
What I mean is that we must learn to see and decide what we want to represent. How to do it comes later and is somehow easier.
This is why taking seriously photographs helps a lot in my opinion.

nickchun

@massimo Yes, I wonder with projects like those, what the builders actually think of them.
I've started looking more seriously at photos in terms of how materials actually look in an image as opposed to how you think they should look. Well composed photos are a great inspiration.

That's great advice. You really see this in your renders especially when you see the reference photos.

The glass in the windows is it a solid volume or 2 planes? It is incredibly accurate in terms of how it is reflecting. There's more at play rather than a simple glass shader.

Thea really is a good engine.

I modeled the windows more or less like the real things. Well, of course, more schematic. So there are two glass panels with thickness and with a cavity between them.
Here you have a rough section in SU of the big windows next to a floor slab.

The material is a thin film glass with a slight blue-green tint in the trasmittance slot and a very slight and enlarged perlin noise procedural as a bump map in order to simulate some imperceptible distortion.
Here you have a SS of the material.

Indeed and, regarding materials, I think that glass and metals is where Thea really excels.

@massimo I'm gonna try this in Rayscaper. It uses the newer PBR disney shader and I wonder how it handles glass when you apply real world properties to both geometry and the shader.

It has a classic glass shader along with the 'Fast' glass. But when I see how Thea produced such accurate results it would be interesting to see.

Thanks for sharing that. The glass reflections really were on point in your renders and now I can see why.

Good, and then share the results please. It's always nice to see these experiments. I recommend you to choose a photo of the real thing and then to try to mimic it.

Here, for example, you have a comparison between reality (first pic) and render (second pic).

The render was made long time ago and it's one of a set of images I made of the "Veliero" bookcase by Franco Albini.

In this case, however, the story was way more complicated because the model was more articulated and also some plastic thin film between the two glass panels was involved. So, if I remember well, I had to use also Thea's container feature. I achieved the result with trials and errors by working on the model and materials at the same time.

You're welcome.

@massimo Stunning work. Glad to see you posting again.

@tuna1957 Thanks a lot Tuna.
