Texture extraction > 

Extract a texture map

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

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

2. Select Normal Map, Displacement Map, or both in the Maps to Generate options.
3. Specify the low resolution (target) model by selecting it within the 3D View, then click Use Selected.

   The target model name appears in the Target Model field.

4. Specify the high resolution (source) model(s) whose sculpted detail will is to be sampled to generate a normal or displacement map by selecting it in the 3D View, then click Add Selected.

   The source model name(s) appears in the Source Models list. If an incorrect items appears in the list of source items, simply hightligh the item in the list and click Remove.

5. Specify the Search Distance for the extraction by entering a value.

   The Search Distance is a physical measurement that determines how far the texture extraction feature will search to find any sculpted detail on the source model(s). It should be slightly larger than the distance between the maximum absolute displacement between the high resolution (source) mesh and the low resolution (target) mesh. Alternately, you can select the Best Guess option if you are unsure.

   NoteYou can also estimate the maximum displacement distance between two surfaces within Mudbox by using the vertical line that indicates the brush strength as a guide. This line represents the physical distance in the current Mudbox units (the default is centimeters).
6. Specify the Image Size for output.

   The Image Size determines the resolution for the map as well as the resolution of the surface sampling that occurs between the source and target mesh.

7. Specify the Bit per Channel for the output texture(s). For more information, see The importance of image bit depth.
8. Enter a Base File Name that will be used for the prefix of each texture file output.
9. Press the Extract button to begin the texture map extraction.

   A window appears during the extraction process to indicate the progress of the extraction operation.

   NoteMudbox supports the extraction of displacement maps on models with UVs that exist outside the 0-1 range. Each UV tile is extracted as a separate image file and saved to the extracted files directory. These files use the naming convention: <filename>_u1_v1_g1.tiffwhere the U and V flags indicate the UV tile coordinates, and g indicates the gain value for displacement.

If the texture extraction process fails to produce a map, or the map that gets produced doesn’t meet your expectations, see Troubleshoot texture extraction.
