You must enable enhanced layer blending to use this feature.
To enable enhanced layer blending:
On the Main menu, click Garment.
Click Enhanced Layer Blending.
You can use this feature to blend materials to underlying materials. For example, to add a special finish effect to jeans, or for realistic display of knitted pieces.
Select this option to:
Disable all the material maps other than diffuse.
Inherit the maps of all the materials that are under (a lower z-index) the selected material.
For example, assume you have artwork on top of a pattern piece. Selecting the option for the artwork means that all the artwork material maps, except diffuse, are ignored. In addition, the material maps for the pattern piece are used by the artwork.
If you have artwork on top of a pattern piece on top of another artwork on top of a base fabric, selecting the option for the top artwork means that all the artwork material maps, except diffuse, are ignored. In addition, the material maps for the pattern piece, the other artwork, and the base fabric are all used by the top artwork.
The following image shows the feature in use.
This feature is available when editing artwork, seam, and trim properties.
