Detailed Description

SubUV animation asset, which caches bounding geometry for regions in the SubUVTexture with non-zero opacity. Particle emitters with a SubUV module which use this asset leverage the optimal bounding geometry to reduce overdraw.

AlphaThreshold

float32 AlphaThreshold

Alpha channel values larger than the threshold are considered occupied and will be contained in the bounding geometry. Raising this threshold slightly can reduce overdraw in particles using this animation asset.

BoundingMode

ESubUVBoundingVertexCount BoundingMode

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

OpacitySourceMode

EOpacitySourceMode OpacitySourceMode

SubImages_Horizontal

int SubImages_Horizontal

The number of sub-images horizontally in the texture.

SubImages_Vertical

int SubImages_Vertical

The number of sub-images vertically in the texture.

SubUVTexture

UTexture2D SubUVTexture

Texture to generate bounding geometry from.
