Geometry Nodes is a node-based system in Blender for creating and manipulating geometry procedurally. Introduced in version 2.92, it allows for non-destructive modeling and advanced effects by connecting nodes to define workflows. Use this tag for questions about creating, modifying, or troubleshooting setups using Geometry Nodes.
