Physics-based prefab scattering & stacking tool. Paint objects directly in the Scene View — they fall and settle using real PhysX simulation.Editor-only tool. Contains no runtime code, shaders, or materials. Works with all render pipelines. Requires 3D Physics (PhysX) enabled in Project Settings.PhysiStack PRO lets you scatter and stack prefabs in your Unity scenes using real-time physics. Instead of placing objects by hand, you simply paint with a brush in the Scene View and watch them fall, collide, and settle naturally.Three spawn modes give you full control:Instant — objects are spawned and simulated immediately as you paint, settling into natural piles before you lift the brush.Place & Drop — stage objects mid-air while painting, then release the mouse to drop them all at once for a controlled avalanche effect.Single Place — precise click-or-drag placement on any surface in the scene, no target surface required. Uses its own dedicated prefab list.Once you're happy with the result, the built-in Bake and Combine tools let you optimise the scene in one click — remove physics components, mark objects as static, or merge meshes by material to minimise draw calls.All operations are fully undoable and editor-only — nothing is added to your player build.Editor-only EditorWindow tool — zero runtime overhead3 spawn modes: Instant, Place & Drop, Single PlaceBrush-based painting with adjustable size, density, drop height and spacingSupports stacking on already-placed objects without extra setupSeparate prefab list for Single Place modeOne-click Bake (Static Batching) and Combine (Mesh Merge by material)Full Undo support for all scene operationsCompatible with Built-in, URP, HDRP and Custom render pipelinesSupports Unity 2021.3 LTS and newer (including Unity 6)No third-party dependenciesAI was used as a coding assistant during the development and refinement process. The tool concept, initial codebase, design decisions, and testing were carried out by the developer. AI assistance was used to help implement specific features (such as the Single Place prefab list and drag-and-drop handling improvements), fix bugs, improve cross-version Unity API compatibility, and write store listing copy and documentation. All AI-generated code was reviewed, tested in Unity, and adjusted by the developer before inclusion in the final package.
