Holograms studies

Last week I started to prepare this study, it was for a challenge for a VFX Community from Brazil and I decided to participate in the last moment, even because I was the one who gave the theme :D

I was trying to find a new way to create a hologram in UE5, and after a tip of my good friend Cristiano Silva - chrisilva.artstation.com - I decided to explore the Thin Translucent in Translucent Blend Mode, and I'm pretty happy with the results. Thin Translucent is used to create something like glass, but it works pretty well and with a cool back-face culling. It's possible to adjust the transparency to make the content in the back visible, so it's a very nice solution for holograms. It's probably a bit too bright, but the deadline was finishing, so I decided to stop to work on it.

Note: the character is Muriel from Paragon. The model and animations are available for free at Epic Store

The Hologram shader structure, just a few variations of lines and noise scrolling, some scrolling textures to create the displacement, but the most important for this technique was the Thin Translucent Material node that we need to add and connect a color

The shader for the light from the bottom, which is basically a cone with a shader using inverse fresnel to create the smooth borders
