User Asset Data

Unreal Engine provides a mechanism to add metadata to UObject. Metadata can provide additional contextual information the developers or across application boundaries.

Simplygon specific tags

The Simplygon UE4 plugin provides a specialized class to tag actors with the following tags:

Tag	Description
Clipping Geometry	Tag an actor as clipping geometry.
Occluder	Tag an actor as an occluder.

These tags can be leveraged by the integration to provide additional data to the Simplygon API (i.e additional visibility or clipping information).
