QuickAssembly is an add-on that automates the creation of Geometry Nodes and instancing setups. It allows users to quickly generate linear, radial, brick, and curve arrays, or scatter objects and collections across surfaces, volumes, and based on textures. The tool provides a user interface to manipulate procedural parameters without needing to manually build the underlying node trees.

The toolset includes multiple procedural generation effects, such as building snow accummulation, generating fog volumes, creating static rain particles, and applying surface damage. It also features utilities for shrinkwrapping meshes, randomizing object transformations, and setting up image texture projectors for Area Lights in the Cycles render engine. Additionally, users can control camera composition and HDRI maps directly from the add-on's interface.
