The tyBoolean modifier is an experimental modifier capable of performing boolean CSG operations on a mesh. It can often provide results that contain less artifacts than boolean operations performed with 3ds Max’s default boolean compound objects. It will also take the reference object’s animated transformation changes into effect when performing its operations.
The object the modifier is applied to is object A.
Union: joins object A and B together, into a single mesh.
Intersection: computes the intersection between object A and B as the resulting mesh.
Subtraction (A - B): subtracts object A from B and returns the resulting mesh.
Subtraction (B - A): subtracts object B from A and returns the resulting mesh.
Slice (A - B): subtracts object A from B (without capping subtracted faces) and returns the resulting mesh.
Slice (B - A): subtracts object B from A (without capping subtracted faces) and returns the resulting mesh.
If your mesh has shell surfaces (ie, a closed mesh with thickness), this option should be disabled. If this option is not disabled for shell surfaces, the inside and outside of the shell will be processed separately and may not return the desired result.
