Dividing Cloth Material Areas by RGB Mask

Each cloth item in Character Creator can have more than one material. By means of using specially designed RGBCMY mask image, the cloth can be divided into different divisions of fabric materials.

Examining Material Divisions on Cloth

Follow the steps below to check out the distribution of the materials applied on a piece of cloth.

  1. Create a new project.
  2. Apply a piece of cloth to the character.
  3. Make sure the cloth is selected. In the Modify panel, go to the Appearance >> Cloth >> Cloth Item >> Cloth Item >> Input Maps node.
  4. In the Diagnostic section, make sure the Mode drop-down list shows RGB Mask, then activate the Enable box.
  5. The distribution of the divisions for materials are displayed and covered on the entire cloth (in this case, the RGB mask image is composed of all Black-RGBCMY colors to divide the entire cloth into several divisions of materials).
  6. The input mask for these divisions can be found in the Input Maps section >> RGB Mask channel.

    This image is made by Reallusion and embedded in the cloth.
