3Darrayer

3Darrayer is a term used in 3D graphics to describe a utility that generates arrays of a single source object or multiple objects in a structured spatial pattern. The tool is designed to automate repetitive placement tasks, enabling artists and developers to populate scenes, instantiate assets for simulations, or create consistent test rigs. It is commonly employed in product visualization, architectural scenes, game environments, and voxel art workflows.

Core functionality centers on controlling the placement, orientation, and scale of object copies. Users can choose from grid, cylindrical, or hexagonal layouts, and adjust parameters such as count, spacing, rotation, and offset. Many implementations support per-instance variation, including small random perturbations in position, rotation, or scale to avoid uniformity. The tool typically supports instanced rendering to keep performance high when dealing with large numbers of copies, and can export results as common formats (OBJ, STL, GLTF) or write directly into a host scene via a plugin.

Workflows often involve importing a source model, configuring the array rules, previewing the arrangement, and exporting the assembled cluster to a file or a target engine. 3Darrayers may be standalone applications, or plugins and scripts integrated with modeling packages such as Blender or game engines like Unity and Unreal. Some versions expose scripting APIs (Python, JavaScript) for procedural generation in workflows and pipelines.

Because 3Darrayer is a general descriptor rather than a single standardized product, there are multiple implementations with differing interfaces and licenses. The concept remains popular among artists who need scalable, repeatable placement of assets and among developers building content pipelines that require procedural scene generation.
