Hello all,
Here a new Rhino lover.
I have been trying to reproduce the Modeling a Simple Glass video tutorial with Rhino8 (https://vimeo.com/49597954), but when applying the water material, it does not look the same to me as in the video tutorial (it looks as a dark matter instead of transparent liquid).
Any tip to solve this?
Hi @Ander
Impossible to tell without some more details. Post your file (just click the little Upload in the middle of the toolbar above)
or at least post the material settings for your glass and water materials.

I’m going to guess that the color of the liquid material is quite dark. For Raytraced and Rhino Render since Rhino 7 you need to take the color you want, but then make it light. Typically increasing the value, sometimes desaturate - or a combination of.
Think of the colors as filters. If you put in black in a glass material then you won’t get any light filtering through, since black filters out everything.
See for instance this reply in another topic:

You’re using a custom material. That’s a bit broken before 8.13, and you’re using 8.12.
This is how it looks like in internal 8.14 (which will become the next Service Release Candidate next week Tuesday)
Anyway, until you update you can also just use a Glass material and set the IOR to that of water, 1.33
Thank you Nathan. Applying the glass material and IOR of water (1.33) the result looks perfect!
It is curious though, the tutorial video suggest to create a custom material, then apply full transparency (100%), and then set the IOR of water: 1.33. This are the settings that I have applied in this case (using the by defect color: white), but the result is still the same. I will wait for the new release then to try it again.
The tutorial is a bit old. You’re better off using either one of the existing material types (Glass, Gem, Paint, Metal) or Physically Based. The custom material is a legacy material, the physically based material is its successor.
Thank you for your help Nathan.
the custom seems to have some settings which i am not sure how to translate if at all to PB. PB only has roughness as a general parameter while in custom as seen in the image below there is one parameter for transparency clarity. also the reflectivity seems to have its own parameter in the custom materials.
the pb generally looks rather simplified, or is there anything going to be exposed sooner or later, if there is anything more to add i mean?
Through Detailed Settings add Opacity, then set Opacity Roughness.
