FDynamicMeshEditor::SetTriangleUVsFromProjection

Project triangles onto a plane defined by the ProjectionFrame and use that to create/set new shared per-triangle UVs.

Windows

MacOS

Linux

Syntax

void SetTriangleUVsFromProjection
(
    const TArray< int32 > & Triangles,
    const FFrame3d & ProjectionFrame,
    float UVScaleFactor,
    const FVector2f & UVTranslation,
    bool bShiftToOrigin,
    int32 UVLayerIndex
)

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

Parameter	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)
