Syntax

static bool CreateLightMapUVLayout
(
    FMeshDescription & MeshDescription,
    int32 SrcLightmapIndex,
    int32 DstLightmapIndex,
    int32 MinLightmapResolution,
    ELightmapUVVersion LightmapUVVersion,
    const FOverlappingCorners & OverlappingCorners
)

Remarks

Find and pack UV charts for lightmap. The packing algorithm uses a rasterization method, hence the resolution parameter.

If the given minimum resolution is not enough to handle all the charts, generation will fail.

Returns

UV layout correctly generated

Parameters

Parameter	Description
MeshDescription	Edited mesh
SrcLightmapIndex	index of the source UV channel
DstLightmapIndex	index of the destination UV channel
MinLightmapResolution	Minimum resolution used for the packing
LightmapUVVersion	Algorithm version
OverlappingCorners	Overlapping corners of the given mesh
