This feature lets users export masks out of Mixer that can then be used further in other DCCs. These masks have a variety of uses, for example, they can be used for creating complex assets or large environments while optimizing texture memory usage or creating variations on the fly. Using masks can make iterations faster while giving full control over texel density in your DCC.
Mixer allows users to export any mask in a few easy steps.
As mentioned in the Create Masks section, layers can be masked in different ways within Mixer i.e. procedural masks, paint masks or material IDs. When exporting masks, it is important to note that the mask information in a layer is a result of height blending, opacity changes and UV/Placement settings in addition to any masks that are added to the layer by the user. When selecting the mask information from a layer, the final result of a layer’s mask information will be sent to a custom channel.
