Quick Guide: Using High-to-Low Poly Baking (New for v5.2)

Follow these steps to transfer surface details from a high-poly model to its low-poly version.

  1. Keep both the original high-poly model and its reduced low-poly version in the scene. Make sure they are positioned to overlap correctly.
  2. Open the High-to-Low Poly Baking panel.
  3. Set the high-poly source and low-poly target mesh models.
  4. Select Normal Baking Options.
    • High-to-Low Poly Baking: Bakes mesh bumps, folds, and the Normal map from the high-poly source together into the Normal channel of the low-poly target.
    • Normal Map Baking: Bakes the Normal map from the high-poly source into the Normal channel of the low-poly target.
  5. Keep Use Cage (Low Poly) enabled. Adjust Cage Offset as needed to enclose the high-poly model. Enable Preview Cage to inspect the coverage.
  6. Enable Auto Unwrap UVs if you want the system to generate new UVs for the target. Set the desired Texture Size.
  7. Click Bake Textures button to start baking. The generated Normal Map will be automatically applied to the low-poly model.
ClosedTip:

If the cage cannot fully enclose the high-poly model, adjust the low-poly mesh using Edit Mesh before baking to avoid projection errors.
