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.

SubUVTexture
Texture to generate bounding geometry from. |
UTexture2D* | 0x28 | |
|
SubImages_Horizontal
The number of sub-images horizontally in the texture |
int32_t | 0x30 | |
|
SubImages_Vertical
The number of sub-images vertically in the texture |
int32_t | 0x34 | |
|
BoundingMode
More bounding vertices results in reduced overdraw, but adds more triangle overhead. |
ESubUVBoundingVertexCount | 0x38 | |
| OpacitySourceMode | EOpacitySourceMode | 0x39 | |
|
AlphaThreshold
Alpha channel values larger than the threshold are considered occupied and will be contained in the bounding geometry. |
float | 0x3c |
