SplineArchitectBoolean

1. What is SplineArchitectBoolean?

SplineArchitectBoolean is an actor that allows performing boolean operations on SplineArchitectWall floor or ceiling meshes. This lets you cut holes for stairs or similar features. The Boolean shape can be any StaticMesh asset.

2. How to create a SplineArchitectBoolean?

There are two ways to create a SplineArchitectBoolean actor:

• The first way is to find it in the actor creation menu and drag it into the level.

• The second way is simply to press the "Add Boolean" button in the Spline Architect utility widget. This button does exactly the same as described above. The new SplineArchitectBoolean will spawn at the center of the viewport in the level. If it touches a SplineArchitectWall, it will automatically be added to the "Booleans to Use" array in that SplineArchitectWall actor.

3. How to use SplineArchitectBoolean?

Description	Image
A SplineArchitectBoolean actor can be used with one or multiple SplineArchitectWall actors. To cut a hole in a SplineArchitectWall, you must add the SplineArchitectBoolean to the "Booleans to Use" array in the SplineArchitectWall actor.
Booleans can be of any shape; the shape is copied from a StaticMesh asset.
When changing the mesh or position of a SplineArchitectBoolean, the associated SplineArchitectWall actors won’t update automatically and need to be regenerated. This can be done easily by selecting the SplineArchitectWall actor and pressing "UnBake" or "Bake" on the actor itself, or "Unbake Connected" or "Rebake Connected" in the utility widget.
