The tySlice modifier is an optimized alternative to 3ds Max’s built-in Slice modifier, that has options for capping slice holes, multi-object slice plane input, etc.
Gizmo: the slice will be controlled by the modifier’s sub-object gizmo.
Object: the slices will be controlled by the z-axis of input object transforms.
Object list: the list of input objects to use as slice planes.
Split: the input mesh will be split in half along the slice plane(s).
Refine: the input mesh will be split along each refinement slice plane.
Remove top: the input mesh will be split along the slice plane(s) and any vertices above the slice plane will be removed.
Remove bottom: the input mesh will be split along the slice plane(s) and any vertices below the slice plane will be removed.
Slices: the number of refinement slices.
Spread: the distance between refinement slices.
Above/Below: controls whether refinement slices will be created above/below the original slice plane(s).
Weld seams: controls whether the edges between refinement slices will be welded.
Override cap MatID: controls whether cap faces will be given a material ID override.
ID: the cap face material ID value.
Generate cap UVs: controls whether UVW coordinates will be generated on new cap faces.
Normalize: controls whether cap UVW coordinates will be normalized.
Size: the size of the cap face UVW coordinates.
