Hi there...
There's another try. A latex cover...
I did it with Lightwave, using cloth dynamics over a car.
The spot efx was made with a circular grayscale mapped in the ground.
Afterall, I used the freeware Hotpixels to remove the fireflies. :D
Comments are welcome.
BR.

Funny model, I like it.

I got poor result with denoiser softwares (no effect or on the opposite blurry image).

To reduce fireflies (as they are placed randomly at each render), you can render two times and add the second pass over the first one with 50% transparency (in Photoshop or Gimp for example).

Then you can remove the remaining brighter fireflies with the one pixel clone pencil.

I also noticed that the amount of fireflies depends a lot on the hdr image choosen for the image base lighting.

Nota : I'm sorry for the images displayed full screen I haven't been able to find out how works the "attachment" system.

I have tried to upload through the attachment feature at the bottom of the page, without success (I use IE7).

ROUBAL :
You should do some better composition.
Right now its a standard "must see all" family-type photo composition.
You should try do a range with dof and off angles to catch the details.
Also play with the post filters and exposure/contrast relations.
The carpet doesnt help I think, it sucks to much light - a carpet does that, but it makes your scene extremly heavy.

You got the scene and the shaders, It just needs to be framed and color corrected better.

@Gk : I'd really want to improve the scene and choose other angles, but as said before, once every material adjusted Octane crashes as soon I move in the view, or as soon I change the ibl map.
Last time it crashed when I switched to Photoshop Elements to paste the screen capture. So I have never been able to get more than one image from a setup, and adjusting all materials again takes at least one hour each time. :cry:

It is like building a house of cards with an air fan on the table ! :roll:

For the "heavy" look of the scene, it is what I wanted. It is not a clear-empty modern appartment. It was the style of years 1920-1930 before Art-deco. In fact, I wanted the carpet to be even darker, but it catched too much light.
