Hello there Blenderheads, Chris here!
the other day one of my subscribers asked how to create the back of a Redmi K20 Pro smartphone. So I looked at a couple of videos about that phone on Youtube and thought that that crazy shiny shimmery surface would actually be a great challenge and perfect to play with materials in EEVEE! I find the speed of EEVEE and the rather complex material node trees it can handle in real-time simply amazing - just wait and see! It surprises me every time...
Check out the (rather longish) tutorial and you can find the finished .blend file here.
