⚙️ Key Features

🧩 Combine Objects
Join selected mesh objects into a single object — just like pressing Ctrl + J — while keeping all UVs and materials intact.

🎛️ Create Packed UV
Automatically creates a new UV map called “MultiBake”, selects all UV islands, and packs them neatly into one UV space — ready for baking.
(And if you prefer, you can manually adjust UV islands afterward for perfect placement.)

🎨 Select Bake Maps
Choose exactly which maps you want to bake:
✅ Diffuse (Color only, no light)
✅ Ambient Occlusion (AO)
✅ Normal
✅ Roughness
✅ Glossy
✅ Emission
✅ Transmission
✅ UV Map

⚙️ Smart Settings

• Texture Resolutions: 1024, 2048, 4096, or 8192 px

• Adjustable margin between UV islands

• Custom output folder

• Optional Duplicate & Assign mode: automatically duplicates your baked object and builds a new Principled BSDF material with all baked maps connected.

  
  
  
  

🧱 Render Engine Compatibility

✅ Cycles (for Baking)
MultiBake automatically switches to the Cycles render engine when baking begins, sets your device to GPU (if available), and then switches back to Eevee when done.

✅ Eevee (for Viewing & Rendering)
All baked textures work perfectly in Eevee because they use Blender’s Principled BSDF shader.
You can bake in Cycles and still render or preview in Eevee seamlessly.

In short:

• 🧠 Baking happens in Cycles (automatically)

• 💡 Final materials work in Eevee and Cycles

💾 Output

After baking, all textures are saved as PNG files in your selected folder, e.g.:

MultiBake_DIFFUSE.png
MultiBake_NORMAL.png
MultiBake_AO.png
MultiBake_ROUGHNESS.png
MultiBake_GLOSSY.png
MultiBake_EMIT.png
MultiBake_TRANSMISSION.png
MultiBake_UV.png

The duplicated baked object gets a new material named:

_baked_mat

🧠 Perfect For

• Game asset optimization and performance

• Baking multi-material props or characters

• Reducing draw calls for real-time engines

• Exporting clean single-material models to Unity, Unreal, or Sketchfab
