EBillboardMode

Specifies how the impostors should be mapped to the scene.

Key	Value	Comment
`OuterShell`	0x00000000	Prioritize fitting the impostors to the exterior hull of the scene. Better for solid/opaque meshes like buildings/vehicles.
`Foliage`	0x00000001	The impostors fit to the entire volume of the scene. Better for chaotic meshes that has lots of geometry within its volume, like vegetation.

EBoneReductionTargetStopCondition

The stop condition for the bone reducer. Any: the reducer will stop when any single one of the set reduction targets have been reached. All: the reducer will stop when all enabled reduction targets have been set.

Key	Value	Comment
`Any`	0x00000000	Simplygon will stop as soon as one of the reduction targets has been fulfilled.
`All`	0x00000001	Simplygon will continue processing until all of the reduction targets have been fulfilled.

EChartAggregatorMode

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.

EDataCreationPreferences

The flag that specifies how big 'freedom' Simplygon has when it comes to altering vertex/triangle data.

EHoleFilling

HoleFilling defines how aggressively the remesher will fill holes and cavities. What this does is to measure the volume and hole opening sizes of concavities in the input geometry and fill them in in the remeshing if the concavity is large enough with a small enough opening. This removes a lot of unnecessary geometry and is recommended to be kept at it's default rather than turning it off, it will in the vast majority of cases have a positive effect on the result.
