Texture extraction >
Transfer paint layers

The Transfer Paint Layers option allows you to transfer multiple paint layers from one model to another. This option is particularly useful, for example, if:

- You have painted textures on one set of UVs and the UVs change during production. It allows you to transfer the paint work done onto a new mesh.
- You are working in a games environment and you have subdivided your base mesh, sculpted details, and then painted textures for those details. It ensures that when the texture map is reapplied to the base mesh, the pixels will not be distorted.

Essentially, this option allows you to save paint work by baking it onto a new mesh with new UVs.

1. Select Maps > Extract Texture Maps > New Operation.

   The Extract Texture Maps window appears. For a complete description of all the extraction properties, see Extract Texture Maps properties.

2. Select Transfer Paint Layers.
3. Specify the low resolution (target) model by selecting it in the 3D view, then click the Add Selected button. You can also click the Add All button and then select the models that you do not want as the target model and click the Remove button.
4. Select one of the following:
   - Generate one map for all targets
   - Generate a map for each target
5. Smooth Target Model is checked by default. Smooth Target UVs only becomes active when Smooth Target Models is checked.
6. Specify the high resolution (source) model by selecting it in the 3D view, then click the Add Selected button.
7. Specify a Method. Select Subdivision if the source and the target mesh have the same base mesh. If not, choose Ray Casting. If you choose Ray Casting, you can also specify the following:
   - Choose Samples
   - Search Distance
   - Test Both Sides
8. Specify an image size.
9. Specify an Antialiasing value. It is turned off by default.
10. There are three transfer options to choose from:
    - All paint layers
    - Current layers only
    - Visible layers only
11. Specify whether to replace existing layers or add existing layers on the target model.
12. Click Extract to start the paint layer transfer process.
