void SetTriangleUVsFromProjection
&40;
const TArray< int32 > & Triangles,
const FFrame3d & ProjectionFrame,
float UVScaleFactor,
const FVector2f & UVTranslation,
bool bShiftToOrigin,
int32 UVLayerIndex
&41;
Remarks
Project triangles onto a plane defined by the ProjectionFrame and use that to create/set new shared per-triangle UVs. UVs can be translated so that their bbox min-corner is at origin, and scaled by given scale factor This is an older function signature that forwards to the more specific one.
Parameters
| Name | Description |
|---|---|
| Triangles | TArray of triangle IDs |
| ProjectFrame | vertices are projected into XY axes of this frame |
| UVScaleFactor | UVs are scaled by this uniform scale factor |
| UVTranslation | UVs are translated after scaling |
| bShiftToOrigin | Whether to translate the UV coordinates to make their bounding box min corner be (0,0) before applying UVTranslation |
| UVLayerIndex | which UV layer to operate on (must exist) |
