Change a material

Use a material change when the geometry stays the same but its surface changes—for example, Beige Fabric versus Green Fabric, or Walnut versus Oak.

Before you edit

• The product revision already contains a material binding for the choice value.
• Its target points to the intended material slot in the root scene.
• The replacement material exists in the project library.

The current Editor edits hydrated material bindings; it does not create a new binding from this panel.

Edit the material

1. Open Option → Scene Bindings.
2. Find the product option value and scene target.
3. Choose the material asset.
4. Activate the value in preview.
5. Check color, scale, orientation, roughness, and normal detail under representative lighting.
6. Select Save visual bindings.

Runtime result

For a valid selection, the visual response includes a SET_MATERIAL action with targetKey, materialAssetRevisionId, documentUrl, and JSON value data. The renderer loads that immutable material revision and applies it to the target slot.

Common mistakes

• Choosing a material prepared for a different UV layout.
• Targeting a mesh node instead of its material slot.
• Leaving another slot on the same part unchanged.
• Previewing an invalid overall selection; active choice effects are emitted only when valid.

Verify

Switch to another value and back, reload after saving, then test the published revision through resolveConfiguration. Confirm only the intended surface changes.
