Aggregation

Overview

The Aggregation processor reduces the amount of draw calls by taking a scene with multiple objects and materials and converting them to a single object with a single material. It will not produce any geometric changes. The original UV charts are preserved but repacked into a new unified texture atlas. There are some options regarding the UV creation.

Supported components

The Aggregation processor works with:

• Material LOD

  • Mapping image
    Accessible from the mapping image settings.

  • Chart aggregator
    Accessible from the mapping image settings.

• Visibility
  Accessible from the visibility settings. Use it to re-size UV chart sizes depending on how visible they are.
