Luxurious...toilet paper

GPickbrenner · March 31, 2020, 10:12am

Hi guys, first time posting artwork! I am usually doing modeling for 3D-printing and jewelry. But for reasons that should be clear to everyone in times of Corona, I would like to share with you this especially luxurious golden toilet paper. Can you feel the excess?

Is the material used for the toilet paper procedural?

Hi 14AUDDIN, thank you for the first ever reaction on this board to my first posted artwork!
It is just a simple bump map with a toilet paper texture on it.

Okay, I’ll take that one. I see six rolls in the back, I’ll take those if they’re available. Got any more? I’ll take as much as you have, any price.

Very nice. I think the texture on the toilet paper is a bit too much and you could use depth of field.

LoL
Okay, this will be only 39,999.99$ a piece, please

Thank you! Definitely helpful comment
Regarding the dof, I tried to make it more pronounced, but it wouldn’t come out as blurry in the bg.
I tried 0.8 f-stop and 38mm focal length. When I set the toilet paper roll as focal point, the background became unblurry, too. Any thoughts?

In this scene, I set f-stop to 0.2, focal length 50mm and it works fine. Make sure “limits” and “depth of field” is ticked. Try setting f-stop to a lower value.

I hate to be a dissenting voice, but the “paper” looks way to glossy. I feel it would be like wiping with metal.

Hi Roken, you are right, but that is the purpose here - as it is literally golden sheets of toilet “paper”! How it would feel actually using it is another story

Maybe you could try rendering with LuxCore, you might be able to get some nice caustics that way

Hi js,
thanks so much for taking the time to post this!
I had to put the f-stop ridiculously low, at 0.01. Only then could I achieve the desired effect.

This is a great idea. Any tips on how to get quick-started with bump maps in LuxRender? So far I found the resources online not very helpful…

I think your toilet roll is too big, may be 2-3 meters, so the f-stop doesn’t work right
