I want to try produce some glass with bubbles inside. Also with light inside :sunglasses:
Something like on this photo. I have try a raindrop map or a noise map into refraction ior , but this
give me not the same result :(. So if someone push me in the right direction , thanks :slight_smile:

Hi,

Is this a good real-world example of what you’re after?

Is the glass solid and are those just air bubbles inside?

This kind of setup can be created with scatter and some material work:

Hi Konstantin,

Thanks for your reply and the examples.
It should be solid glass with bubbles inside.
Now I have this. With light on and off.
It’s not 100% perfect , but it comes close to it .
Created a glass material as outside , and the inside is made with water drops material
and transparency. Vray5 + rhino 8

Could you please explain how you have don it ? It’s very good.:sunglasses:

Looks good.

Keep in mind that the bubbles should ideally use the inverse of the glass IOR.
If you glass IOR is 1.5 the bubble materials’ IOR should be 1/1.5=0.6666 .

Or you can share the same material but flip the normals of the bubble objects - in this case V-Ray will automatically calculate the correct IOR.

Another trick is to vary the bubble size slightly instead of keeping them all uniform. Even a little randomness in size and distribution tends to make the glass feel much more natural and less CG-perfect, especially in close-up renders.
