Preserving underlying transparency during compositingThe Preserve Underlying Transparency option specifies that the opaque areas of a layer display only when positioned over opaque areas in underlying layers. With this option, you can make a layer display only when it is positioned over the layer below it. It's useful for creating effects such as glints or light reflecting off a polished surface. To preserve underlying transparency: Select the T option in the Layer Switches column for the appropriate layer. ![]() |
