3D Artist and Blender tools developer Casey Sheep shared a new unnamed cool effect with a nice slider created with Geometry Nodes and Shader Nodes for Blender 4.1 and Cycles. It's free to use in all kinds of projects, including commercial use, so you can experiment and share the results with the artist if you come up with something interesting.
