In this Blender livestream we explore several procedural techniques, including how to build a Geometry Nodes droplet generator for creating condensation effects on surfaces.

Starting from a simple sphere, we use Distribute Points on Faces and Instance on Points to generate droplets across a mesh. Then we refine the setup by creating half-sphere droplets, aligning them to surface normals, and randomizing their scale to create natural variation.

Along the way we also explore several other Blender topics from viewer questions, including:

• Geometry Nodes experimentation
• Procedural logo cutouts from images
• Pixelated shader effects
• Smooth cinematic camera movements
• Procedural city generation using Geometry Nodes

Livestream sessions like this are a great way to learn Blender techniques in real time and see how problems are solved step by step.
