Hi,
I have recently gotten into modeling and rendering again and have found that trying to reproduce a photo is a great exercise to improve realism.
Here's my latest, open to suggestions, criticism, nits & picks, etc. Bathtub Oval Freestanding 2020-02-13 18485700000.png

Excellent image!

The textures on the floor aren't as good as the others though. This is where displacement mapping would make all the difference, although it would add to the render time.

The concrete floor and roof textures are also much too even by comparison with the walls, unless they are new concrete, which means it would probably be smoother. The current textures are neither rough nor smooth enough.

You really ought to post the source image so we can compare - I might be being a bit unfair 😉

Thank you for the comments! Here's the original image. It isn't a straight copy as the ivy is hard to replicate. The wall textures are from the SketchUp texture club, but I indented the panels. I believe the bump map is set too high. The floor and ceiling are from the browser and the bump is probably set too low. I concentrated on getting the perspective and lighting as close as possible but also took some liberties. Should probably work harder at getting those exactly right. I also tried Ivy generator and the Ivy plugin but found a little tricky to work with, I couldn't import the.obj and the plugin ran really fast to control (I need to learn to tweak the parameters). Anyway, thanks again for your comments!

Yeah, the ivy Generator is tricky, even more so on the Mac for some reason. Takes a while to get used to.
You see my points about the ceiling and floor though don't you?

The ceiling, like the walls, are old, but the floor looks new. The texture and finish are a total contrast.

The beams are actually a brass/copper colour metal, not wood. I thought they looked a little odd. The connection with the walls has no detail and doesn't look realistic. On the photo the connection is hidden by the plants, so it might be worth playing with the Ivy generator a bit more.

Thanks again. Yes, I need to work on the ivy and the concrete. I will probably work on those textures in PS.
How do I do displacement mapping in Podium?

We don't have displacement mapping in Podium V2.5. We are looking at features for V3, because the new version of our render engine supports the feature.

Early days yet though!

OK, here's a final version (for the time being, need to work on other things). I guess I hadn't realized the original image was also a render, a very good one, so I'm trying to figure out how it was done. The image coming out of Podium is a bit grainy and I'm not sure if it's the HDRI or bump mapping. I will look into that.
Meanwhile, thanks again for your time. You make this forum worth following.

Hi,

Great image. So the Ivy generator created that ivy? Or did you end up using something else? Looks awesome.

Thanks. No, I need to work some more on Ivy generator. The ivy is a composite photo.
