Hello!
I've finally made a Blender tutorial again, and it feels very good! In this project, we'll be using Geometry Nodes to create a procedural emissive trail that follows an empty object. We'll be animating this empty object in real-time using the input from out mouse cursor 2D location. A fun and powerful technique that has many use cases!
In the attachments of this post, you'll find the tutorial project files as well as the Square_Tiled.png texture we're using in this project.
If you're looking for the more advanced GeoNodes setup with some noise displacement on the tail of the trail, you can find it in this pateron post here.
Hope you'll enjoy the technique!
Best,
Polyfjord 🌊
