static bool StripLODGeometry ( [USkeletalMesh](API\Runtime\Engine\Engine\USkeletalMesh) * SkeletalMesh, const int32 LODIndex, [UTexture2D](API\Runtime\Engine\Engine\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.
SkeletalMesh: The skeletalmesh we want to optimize LODIndex: The LOD we want to optimize TextureMask: The texture containing the stripping mask. non black pixel strip triangle, black pixel keep them. Threshold: The threshold we want when comparing the texture value with zero.
