Creating a Specular Map

To create a specular map:

1. In Photoshop, open the file for the diffuse map created in Creating a Diffuse Map. Save the file as <filename>_spec. For example, seersucker_spec. The correct name suffix is essential.

2. On the Main Menu, click Image > Adjustment > Invert. The image is displayed with the inverse colors of the original image.

   

3. On the Main Menu, click Image > Adjustment > Saturation.

4. Make the following adjustments:

   1. Set Saturation to approximately -50.

   2. Set Lightness to approximately -60.

5. Values may differ depending on material.

   

   

6. Save and test the specular map by assigning it to a garment within VStitcher and adjusting the spread. A luster should be apparent on the 3D simulated fabric with a higher spread value.

   

7. Save the file in your preferred file format.
