Vray + Sketchup "physical model" look

[mauman]

Hello Everyone.

 

I work in an architecture office and we have been trying for some time now to prepare a series of renders with a physical model look for a project, using Sketchup 2015 and Vray 2.00.

 

This is approximately the look we are aiming to.. ("physical model look" attachment)

 

Now... my problem is with the trasparent plastic material of the skyscraper. somehow i don't seem to manage to get the look that i want from it, and it rather looks too transparent or completely like a frosted glass.

 

Attached is an example.

 

So far i tried by using the glossiness in the refraction layer of the material but i always get some of the material from the sorroundigs to "color" the inside of the material and i don't want that. It also looks a little bit too much like glass and not plastic. i'm missing that "fog" inside the plastic material when you look through a thick part of it.

 

Any suggestion on how to improve the look of it?

 

I'm also attaching my result so far and the vray material settings.

 

Thank you everybody in advance.

I think you're pretty close to nailing it, but to get that "plastic" look you might want to try using some sub-surface scattering within the glass.

 

Also the big "giveaway" when making something look small is a shallow depth of field.

Thank you Chris. I am close but not getting there makes pretty frustrating

 

Frankly i never heard of sub surface scattering. I'll make a little research about it... \

 

 

 

[edit]

Made the research and it seems like i would need to use a FastSSS material type to obtain it, but my version of vray 4sketchup does not appear to have it. Is there a way to obtain a similar effect using a standard material?

Translucency is SSS in the standard material.

Having not read the post fully I thought you were posting all the above images as you own and hastily posted an 'appropriate' response, my apologies if you read it before I deleted it! The example images you posted are mine, will see if I can look out the original file.

 

From memory I think it was just glossy refraction. And now you have also reminded me that I mis-scaled the whole block relative to the surroundings...

Chris was right, I did use translucency. Set to hybrid mode, in combination with the glossy refraction. Material settings attached.
