Create non-destructive Prefab Variants and standalone prefab combinations with rules, batch generation, validation, previews, and safe output controls.Polynest Prefab Variant Generator is an editor-only productivity tool for Unity 6 that creates Prefab Variants or standalone prefabs from existing prefab sources.Build reusable prefab families without editing source prefabs or shared input materials. Configure visual and structural changes as Variant Rules, inspect planned combinations, validate output paths, and generate assets safely in batches.Key benefits:• Generates Unity Prefab Variants by default, preserving the link to the source prefab.• Supports standalone prefab output when an independent asset is required.• Keeps source prefabs and shared source materials unchanged.• Helps prevent duplicate outputs with validation, duplicate detection, and Auto Rename conflict handling.• Includes isolated previews, a searchable Combination Matrix, presets, and JSON generation manifests.Use it for prop variations, environment sets, character equipment combinations, colour variants, modular assets, and any workflow that needs many controlled prefab variations.• Unity version: Unity 6.3 LTS (6000.3.19f1).• Package type: Editor extension. No Runtime assembly and no player-build code.• Output modes: Prefab Variant and Standalone Prefab.• Non-destructive workflow: source prefabs and shared input materials are never modified.• Built-in Variant Rules: Material Swap, Material Color, Mesh Swap, Child Toggle, Child Group, and explicit Transform Values.• Batch generation with all combinations, selected combinations, and deterministic unique random selection.• Combination planning before asset writes, including duplicate detection and output-path validation.• Default existing-asset conflict policy: Auto Rename.• Isolated editor preview and virtualized, searchable Combination Matrix.• UI Toolkit workspace with Unity Dark and Light theme support.• Preset assets for reusable configurations.• JSON Generation Manifests for generation history and generated-output tracking.• Atomic-style manifest writes to avoid partially written valid-looking manifests.• No external dependencies.• Render-pipeline independent editor workflow.OpenAI ChatGPT was used to assist with portions of the C# editor code and English documentation included in this package. The AI-assisted material was manually reviewed, revised, integrated, and tested by the publisher. The publisher implemented and verified the final architecture, Unity Editor integration, prefab variant generation workflow, input validation, error handling, user interface, and documentation examples. No AI-generated runtime art, audio, models, textures, or prefabs are included.
