ReDupli: The Ultimate Asset Pipeline Automation Tool

Stop wasting hours dragging files between folders and re-exporting models. ReDupli automates the repetitive parts of your game dev workflow, reclaiming up to 2 hours per model for the average professional artist.

❌ The Workflow Drain

You aren't just modeling; you're managing a chaotic cycle:

1. Re-Export: 5 mins × (1 + 20+ loopbacks) for baking in Marmoset or tweaking in Substance.
2. Engine Quality Check: 2 mins × drag into Unity/Unreal, check shading.
3. File Management: 2 mins × Copying for QA, Final folder, and Customer delivery.
4. Materials: 30–60s × Cleaning duplicate .001 slots and unused datablocks.

Total Estimated Time: ~2 Hours per Model just for the export/verify/cleanup cycle.

With ReDupli: Seconds.

ReDupli turns this into one-click actions:

• 🚀 ReEx (One-Click Pipeline): Chains Collection Processing → Export All → Copy Files in one single button press. No more switching tabs.
• 📂 Auto Watcher (Set & Forget): Enable Auto-Watcher in the Copy Files panel. Leave for lunch. When your textures or models update on disk, ReDupli automatically copies them to your Engine/Final folder. No manual dragging.
• 🧹 Material Management: Automatically relink duplicate slots (.001/.002), sort clean, and remove unused materials. Save 30–60 seconds per object cleanup.
• 🛠️ Smart Collections Processor: Flatten LP models with trims & modifiers. Apply materials, convert to mesh, join, and rename in one go. Perfect for Unity/Unreal ready packages.

🛠️ Included Tools

• Collections Processor: Process entire object hierarchies, apply modifiers, and flatten meshes for export.

• Multi-Presets Exporter (ReEx): Export up to 3 formats (FBX, OBJ, GLTF) simultaneously using different presets.

• File Copy with Watcher: Auto-sync files to Unity/Unreal directories instantly when timestamp changes.

• Material Manager: Detect/Remove duplicates and clean orphaned datablocks.

• UDIM Tools:

• Generator: Detect UDIM tiles and assign materials (_part1, _part2).

• Renamer: Rename UDIM textures (Box_diff.1001.png → Box_part1_diff.png) for standard engines.

⏱️ By The Numbers: Your Savings for ONE LOOP

(Estimates based on a standard blender>marmoset>substance>game-engine>final-folder re-do loop. Savings scale with complexity.)

👋 Perfect For You If:

• ✅ You bake textures in Marmoset / Keyshot and need multiple export versions.
• ✅ You use Game Engines (Unity/Unreal) for QA and need to sync folders automatically.
• ✅ You work with LP models with Trims & Modifiers (Auto-join logic works best here).
• ✅ You find yourself constantly re-exporting due to shading issues.
• ✅ You are tired of dragging hundreds of files to final delivery folders.

Don't let manual file management slow down your pipeline. Upgrade your workflow with ReDupli today.
