Parametric Array empowers you to create highly complex, richly varied parametric arrays, significantly enhancing your level design pipeline. You can seamlessly incorporate Blueprint Actors, light sources, Static and even Skeletal Meshes into your arrays, distributing them with true randomness for natural, organic results.
One of its most powerful features is intelligent optimization. The plug-in automatically detects identical Static Meshes that share the same materials and merges them into HISM Components (Hierarchical Instanced Static Meshes) when enabled. This dramatically improves rendering performance while preserving visual diversity.
Instances can also be distributed along splines, making it ideal for roads, fences, corridors, railings, pipelines, and other spline-based structures.
Beyond placement, the plug-in offers advanced material control. You can assign different materials to the same instance and organize various assets into collections. These collections can then be duplicated and distributed procedurally, giving you maximum creative flexibility with minimal manual effort.
The Parametric Array Plug-in is particularly effective for building large-scale environments — from architectural structures filled with interior elements like furniture and lighting, to complex urban scenes populated with benches, streetlights, and other city assets. It works exceptionally well in combination with Megalights, enabling visually rich yet performance-efficient scenes.
For further optimization, you can configure Cull Distance and Max Draw Distance for all generated objects, ensuring excellent runtime performance even in large environments.
Additionally, every generated item remains accessible at runtime. Through Blueprints, you can retrieve and modify individual instances dynamically, allowing for interactive and responsive gameplay systems.
