Bonus Setup: Frozen Sphere (Patreon)

EDIT: Added Houdini 19 compatible .hipnc file.

While preparing our current tutorial on how to simulate the growth of a snowflake, we received a question on how to create a freezing bubble. Good timing! Turns out that you can modify the snowflake setup to allow for some frosty ice crystals to form on a sphere. Attached you'll find this setup, ready to be rendered using Redshift.

P.S.: To render the final image you'll need to download the "Winter Forest" HDR from http://www.hdrlabs.com/sibl/archive.html
