A procedural Snowflake Material, based on the Coding Challenge #127: Brownian Tree Snowflake (https://youtu.be/XUA8UREROYE) by Daniel Shiffman made 100% in Substance Designer. This should be my entry for Nodevember Day 18 - Growth, but I couldn't make it in time.

Both Substances are available for free on my gumroad (https://gum.co/jSdoG).
All the best Marco
