Syntax
public class SubUVAnimation : UObject
Remarks

Particle emitters with a SubUV module which use this asset leverage the optimal bounding geometry to reduce overdraw.

Properties

AlphaThreshold

Alpha channel values larger than the threshold are considered occupied and will be contained in the bounding geometry.

Declaration
public float AlphaThreshold { get; set; }
Property Value
Type Description
System.Single
Remarks

Raising this threshold slightly can reduce overdraw in particles using this animation asset.

BoundingMode

More bounding vertices results in reduced overdraw, but adds more triangle overhead.

Declaration
public byte BoundingMode { get; set; }
Property Value
Type Description
System.Byte
Remarks

The eight vertex mode is best used when the SubUV texture has a lot of space to cut out that is not captured by the four vertex version, and when the particles using the texture will be few and large.
