The AggregationProcessor 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.
It can also volumetrically cull triangles on insides of objects that are combined using the EnableGeometryCulling setting.
# Supported components
