Here I have two useful ICE-compounds I use quite often. The fist one caps all holes in a Mesh.
Picture 1: A polymesh with many Holes.
Picture 2: The compound caps all holes on a mesh.
picture 3: The insert_NGones compound Inserts all polygones with more than 4 points.
This compound gets useful when working e.g. with the “Create Extrusion Along Strands” compound. After doing the extrusion with this compound along stands the top and bottom cap are not-smoothable ngones. When using a Inset-NGones compound after the extrusion, the meshes get flat caps when smoothing them.
