TUTORIAL: How To Easily Grow a Snowflake in Blender 3.0 using Geometry Nodes!
I love Blender...
But not as much a I love Blender 3.0!
I have intentionally been holding off on making anything in Blender 3.0 prior to it becoming a full version and, woah, what a full version it is!
Geometry Nodes are kicking it out of the park! I mean, Blender was good, but now it's just amazing. It's slowly becoming a little free Houdini. The renderer in Houdini is not great, but the one in Blender now is blistering fast even on my little 1080ti. For a fully integrated GPU renderer, it is something any company should consider using now.
Anyhoo, this tutorial is about the process of making a snowflake completely out of Geometry Nodes, not a shape primitive in site, as well as then linking inputs into the geometry node modifier so we can animate the growth of each stem individually. It's a little long, so here is a breakdown for you to go to the bits you're most interested in:
00:00 - intro
02:36 - into the geometry nodes side.
03:55 - making your first curve.
05:55 - making the curve a mesh.
07:02 - making the radius of the mesh different over it's length.
09:03 - remapping the parametric length of the radius.
10:16 - adding randomness to the radius.
13:40 - adjust the radius over it's length with vector curve.
19:48 - adding a trim curve to grow the stem with animation
21:23 - using this setup made to make the other stems
22:25 - Duplicating the setup, adding a transform then connecting it to the group output.
25:29 - replicating the process to make duplicates and mirrored instances with geometry transforms and join geometry nodes.
41:01 - connecting the trim curves to the input of the geometry node to allow us to animate them.
44:29 - turning our one stem into multiple instances, again using geometry transforms of one element into the join geometry.
46:13 - Adjusting the arms in the geo node to make them appear nicer
49:15 - SAVE!
49:30 - Start animating the snowflakes growth using the Geometry Node Inputs we created.
55:11 - Shading geometry made entirely in Geometry Nodes
58:56 - Outro and thoughts
