I'm trying to create a similar effect to this. And I found a nice tutorial with something similar. However, I wasn't able to add a text there. So it looks like the material setup is not using any volumetrics at all? Can you help to decipher this shader?

I get something pretty close:

I've created this mesh from the logo:

Then I've given it a pure white Emission shader for the bottom, and this node setup for the walls, which is basically a mix between an Emission of a multicolor ColorRamp and a Transparent, with a gradient along the Z axis, and before the Output, a Layer Weight to give it a pink emission on the edges:

If you want to animate, use an empty in the Texure Coordinate to mix the materials with a Transparent node:

  • $\begingroup$ This is awesome! And you have that minimal setup compared to the original. $\endgroup$ – valk Dec 24 '20 at 18:40
  • $\begingroup$ Did the same setup as yours but it didn't look right. Then discovered that need to turn on Alpha Blend in the Material > Settings > Blend Mode, and check that everything basically as is here blender.stackexchange.com/questions/81851/… $\endgroup$ – valk Dec 24 '20 at 21:07
  • $\begingroup$ yes I didn't go into much detail, if you ever don't understand something please ask ;) $\endgroup$ – moonboots Dec 24 '20 at 22:23
