Description
MergeUVIslands (v1)
Merge adjacent UV Islands with similar normals for a specific UV channel
Input(s) : Collection [Intrinsic] - Target Collection FaceSelection - Faces to auto unwrap, no selection means all faces UVChannel - UV channel to unwrap into ( 0 by default ) AreaDistortionThreshold - Threshold for allowed area distortion from merging islands (when we use ExpMap to compute new UVs for the merged island) MaxNormalDeviationDeg - Threshold for allowed normal deviation between merge-able islands NormalSmoothingRounds - Amount of normal smoothing to apply when computing new UVs for merged islands. More smoothing will result in UV maps that are less sensitive to local surface shape. NormalSmoothingAlpha - Strength of normal smoothing to apply when computing new UVs for merged islands. Stronger smoothing will result in UV maps that are less sensitive to local surface shape.
Output(s): Collection [Passthrough] - Target Collection UVChannel [Passthrough] - UV channel to unwrap into ( 0 by default )
