 Steps:
 1. Create a combined orbital tissue segment from individual segments
 2. Create a 0.5 mm gap between tissue segment & bony orbit: expand the skull by 0.5mm and subtract tissue segment from it
-3. Smoothing the segment and removing isolated voxels.
+3. Smoothing the segment, fill all internal holes, and removing isolated voxels.
 4. Convert combined orbital tissue segment to a surface model and downsample + uniform remesh it to about 1.5k pts
 5. Using a customized gmsh script to do the meshing. Redo surface remesh and/or gmsh spacing set up until getting around 10 to 15K tetrahedra.
 6. Convert individual tissue segments to models with <1k pts for MeshROI tet selection in SOFA
