# class ChartAggregatorSettings

Settings for the chart aggregator.

# Properties

Property Description
ChartAggregatorMode Determines which method to use when aggregating the UVs. TextureSizeProportions - Aggregated UV charts will be scaled to keep their relative pixel density relative to all other UV charts. The user can still set the size of the output texture maps. SurfaceArea - Aggregated UV charts will have their size set based on its actual geometrical size. OriginalPixelDensity - The combined atlas will be resized to fit each chart so that all charts retain the same amount of pixels as they originally had. This will override any manually set texture size. UVSizeProportions - Aggregated UV charts will have their size set based on its original UV size, disregarding the size of the texture they are used in.
LockUVRotation Only used when the TexCoordGeneratorType is ChartAggregator. If ChartAggregatorLockUVRotation is enabled, only the original UV rotation will be used. Otherwise 4 rotations are used (90 degree rotations).
OriginalChartProportionsChannel Only used when the TexCoordGeneratorType is ChartAggregator. Set ChartAggregatorKeepOriginalChartProportionsFromChannel to an SG_MATERIAL_CHANNEL_[...]. This channel determines which texture channel to look at when determining which chart proportions to keep.
OriginalTexCoordLevel Only used when the TexCoordGeneratorType is ChartAggregator. Set the texture coordinate level to get charts from. If the ChartAggregatorOriginalTexCoordName ha been set, the ChartAggregatorOriginalTexCoordLevel is not used.
OriginalTexCoordName Only used when the TexCoordGeneratorType is ChartAggregator. Set the name of the texture coordinate level to get charts from. If not set, it will use the ChartAggregatorOriginalTexCoordLevel (index) instead.
SeparateOverlappingCharts Only used when the TexCoordGeneratorType is ChartAggregator. If set, charts that are overlapping in the original texture coords will be separated.
SurfaceAreaScale If multiple UV charts overlap and have the same material, SurfaceAreaScale specifies which of those instances determines the the output scale. It is only valid when the ChartAggregatorMode is SurfaceArea and SeparateOverlappingCharts is false.

# Static methods

Method Description
IsClassA Returns true if the class is a or is a descendant of the class named as the type parameter.
SafeCast SafeCast makes sure the input object is of a class that can be cast into spChartAggregatorSettings, and if this is the case, returns the object cast into spChartAggregatorSettings.
