Guys hello,
Does anyone has an idea how to create a wireless waves that could look like on images below? Would greatly appreciate any tips.
why not just a plane with the wireless wawe texture and alpha ?
A disc object with multiple gradients would also work.
No guys, it should have a volume, like a fog rings or something.
Then a torus with a volumetric material should do the trick.
Volumes can be layered, but the result is often very close to one of the materials if the values for scattering & color are not extreme enough.
I just did it yesterday when I was trying to make a layered Skin shader like material using the volumetrics.
That i know.
Sorry, for i have expressed poorly - Volume can’t be a Base material in Layered to build upon. 
Since I love challenges , couldn’t let this one pass without giving it a try.
My approach was a bit different from the ones mentioned before.
I did it using alpha channels and depth of field(to give it that foggy effect).
here is the result:
Could you give me more details on your approach please?
