A glass of water with the new glass2 material

[Lord Crc]

Thanks jeanphi, this was my impression as well. I just wanted to make sure it wasn't something I had made up

I'll update my blog post with this and a few other details soon.

Its a great tutorial btw Lord crc, does explain well and show off the new feature well... im now back to my old days of rendering everything in glass. Except now its glass2

[Lord Crc]

Thanks! Always good with some feedback

Just to complete the thread here is my version of a glass2 glass of water (heavily inspired by Eros' scene but more like a wallpaper):

I even tried to add bubbles and I used a glossy material for the straws instead of a matte one

Tks guys for the tutorial... Really helpful.
And here it's my version of Eros' Glass2 Glass of Water, with the bubbles suggested by Daniel.

Eros' Glass2 Glass of Water

The water's surface is kind of weird. But this picture had taken me hours of soft work (really, hours)... so i won't fix in soon.

The bubbles look great, except for the even distribution around the straw. Also, the caustics are nice.

The green part with the following settings:
Interior: Glass
Exterior: Water

Hi

I have the green part (1st page 1st post) but normals outside.
Interior: is orange juice (homogeneous roughglass)
Exterior: is glass (clear glass2)

What material do i need to use for that mesh, is it homogeneous roughglass because it's Interior, or the clear glass2 because the glass internal wall are then like glass external surfaces (clear glass2)?
Can i define 2 materials for that mesh, 1for "normal out side" and another for mesh inside?

It doesn't matter in which direction the normals are pointing. But you eventually have to switch the volume definitions. The exterior volume always is the volume at which the normals are pointing and the interior is the volume the normals are pointing away from.
In your case the volume and material definitions are:

exterior: clear with ior of glass
interior: homogeneous with ior and scattering properties of orange juice
material type: glass2

Hi,
I have a similar setup with some kind of medium, culture dish, cover slips and so on ... I wonder how to assign the volumes to the touching faces. Up to now I use multimaterials for every object.

Lets take culture dish and the medium. I assinged glass2 (inner volume = plastic; outer volume = medium) to the inner faces of my culture dish, while the other faces have glass2 with: Inner volume = plastic; outer volume = air. Thus I gave the outer faces of the medium glass2 (inner volume = medium; outer volume = plastic) or glass2 inner volume = medium; outer volume = air).

I think this will work, right?

My point is that I wonder if the touching faces of culture dish and medium should be congruent or if it would be a better approach to model one object with multimaterials instead of two objects carrying multumaterials. To stay with this setup I would add the surface of the medium to the culture dish and would set up the materials as said before.

Whats the (physical) right way?
