static bool StripLODGeometry (     USkeletalMesh * SkeletalMesh,     const int32 LODIndex,     UTexture2D * TextureMask,     const float Threshold )

Remarks

This function will strip all triangle in the specified LOD that don't have any UV area pointing on a black pixel in the TextureMask. We use the UVChannel 0 to find the pixels in the texture.

@Param SkeletalMesh: The skeletalmesh we want to optimize @Param LODIndex: The LOD we want to optimize @Param TextureMask: The texture containing the stripping mask. non black pixel strip triangle, black pixel keep them. @Param Threshold: The threshold we want when comparing the texture value with zero.
