Box with Frosted-Wavy glass...

[gabyanz]

Good evening to all...

I'm having hard time creating a material for a box that has a translucent/frosted plexyglass ... with a wavy texture.

I've used both translucency both refraction glossiness (that is for sure more time consumer) but I'm not really happy wiht the results... can you help me?

I've attached the reference...

thanks
Gaby

Hi, sorry for the delay. I am sure our forum users would like to help you (including me) but it is hard to understand your problem by looking at the attached picture. Can you post a different image of the material you would like to recreate, so that we can understand how it reacts with light, how objects look behind it, etc?

Thanks a lot for your reply, Maru.

Unfortunately don't have very good references :/ sometimes my clients have to think I'm like a magician.... (now i'm trying to recreate another material without  a precise pantone reference, only terrible photos... really hard)

This should be a resin, textured in the surface, but almost opaque.
I added another photos and a link of the productor... but in the site there is only a photo......

I see that I can achieve the best result combining bump+displace, using a glass/type material. I would like to use transluceny instead of gloss refraction, but It seems too much wax like... and it should be like a textured glass, but less transparent.

thanks anyway :)

Hej gabyanz,

as for the link to 3form it looks like this could help:
http://3dsky.org/3dmodels/show/3d_paniel_briz

(or maybe something similar, 3dsky has a lot of these 3d wall panels).
I have used this panel in one of my last projects.
It´s a pretty high res model and tileable.

I could imagine with reflection, refraction (+ absorption color) and normal bump it should work nicely.
(Though you need a matching bump map).

Hope it helps!
best regards
Nico

Thanks for the tip, Nico.

I could use it for the bump map/normasl map.

It's only a material or it's a modeled panel?

Hej gabyanz,

it´s a 3D model (no textures included).
These waves could be pretty hard to reproduce only with bump or displacement.
So I think this base mesh helps a lot.

best regards
Nico

My attempt. The problem is that I am still not sure what this material looks like in real life.

hey maru, can you tell how to avoid fireflys as you show in example render with them, they hunted me in every scene at chrome and glass material, don't want to create new topics for every scene, but saw all tutorials tips etc, even in gallery people show images with some fireflys on highlight glass or is it normal for corona on bright zone and edges?
Thanks

Either this https://coronarenderer.freshdesk.com/support/solutions/articles/5000529356
or adaptivity and denoising in 1.4 :)

btw these are not fireflies in my rendering - these are reflections of the sun on an uneven surface. You can see the same thing in your photo, only in smaller scale.

Yes but on photo they not square shape like pixel, so we can't use not only 255 white colour, even glossiness with 1.0? Thanks for answer =)
just to make sure in my example not fireflyes too? it was render with denoiser though
