Generic Particle System: Minor update for Set ID node
I was running into a bit of an annoying issue with an animation that used fast-moving particles and motion blur, specifically with particles created through Geometry Nodes. It seems that Blender’s motion blur relies on the ID attribute of any given instance, so if that is changing or repeating, it causes the motion blur to…

Using the Wrap and Ping Pong math nodes to drive particle animation
Wrap and Ping-pong node basics Say you have a particle system, and you’d like the particles to all pulse either all at the same time, or independently from one another. An elegant method of achieving this is with the Wrap and Ping-pong Math nodes. These nodes have similar functions, where upon a value exceeding a…

Generic Particle System update: velocity recalculation, gravity, and collision improvements
I made various changes to the Generic Particle System because there were some things there that weren’t quite right. Rather than taking one velocity attribute and updating it over time based on various conditions, such as collision, proximity to attraction and repulsion objects, etc, I was instead using multiple Set Position nodes, which made all…

Geometry Nodes – Generic Particle System
You ever need to use Geometry Nodes for an effect that doesn’t work well with the basic particle system? You ever get tired of building the same god damn particle system in Geometry Nodes any time you want to emit points and then instance objects on those points? SAY NO MORE! I created a simplified…

Energy Drain Effect – Globules
Another fun little geometry nodes energy drain setup, this time with some SDF grid fun! This setup distributes points either on the faces of the mesh or converts it to its volume, and then instances UV spheres in those points, which then are either attracted or repulsed by an object, and also have some fun…

Cloth Dynamics node: shrinking/expanding vertices over time, and applied forces (Blender 5.2 Alpha)
Blender 5.2 Alpha is out and it has a few incredibly exciting new nodes: Cloth Dynamics, and Geometry Collider. These are new within Geometry Nodes and appear to be the Blender Foundation’s next step in supplanting the old cloth system with a new, stabler one, that works within Geometry Nodes. See CGDive’s video on it…

Energy Drain Effect
This is a drain effect that I often use in order to illustrate muscle theft. This is made out of Some Geometry Nodes Bullshit that basically generates points in an area around an origin object, and then those points fly towards a target object. You can set an object to act as a collider, which…

Using vertex groups and geometry nodes to drive texture visibility
Problem You have a character who you want to make it so that a texture or effect will only show in certain parts of the body, but you do not want to create a whole new grayscale texture to serve as a mask. For example, let’s say you want to create an effect where displacement…
