SplineArchitectWall

1. What is SplineArchitectWall?

SplineArchitectWall is the main class, or actor, where details made from modular meshes will be generated. For SplineArchitectWall to generate meshes, it must have a SplineComponent component.

When attaching one SplineArchitectWall to another, the attached actor will be positioned on its parent and generate meshes on top, like a second floor or similar.

2. How to create a SplineArchitectWall?

You can create a SplineArchitectWall in two ways:

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

For the created actor to generate meshes, you need to add a SplineComponent component to the actor itself.

  • The second and easier way is to simply press the "Add Spline Wall" button in the Spline Architect utility widget. This button does the same as the instructions above. A new SplineArchitectWall will spawn at the viewport center in the level and have a SplineComponent component added.

  • You can create a new SplineArchitectWall and attach it to the selected SplineArchitectWall by pressing "Add Wall to Selected".

3. SplineArchitectWall parameters

1. Preset

The Preset category has a single parameter "Preset," which is a struct specifying exactly how the SplineArchitectWall will be generated, which meshes will be used, etc.

2. Adjust Spline

The Adjust Spline category contains functions for working with the SplineComponent in this actor:

  • Flatten Spline Points sets all spline points' Z positions to the first spline point's Z position, useful if any spline point was accidentally moved on the Z axis.
  • Gridify Spline Points rounds spline points' positions according to the Grid Size vector. Useful for buildings, as by default you might want to copy positions from one point to another; otherwise, manual adjustments result in crooked lines.
  • Mirror Spline X and Y mirrors (flips) spline points, useful if you want two symmetrical walls—you can copy one and mirror it.
  • Reverse Spline Points reverses the order of spline points, useful if a wall is facing the wrong direction.
  • Grid Size specifies the rounding precision for spline point positions.
  • Auto Gridify – when enabled, spline points' positions are automatically rounded.

3. Baking

The Baking category contains functions and parameters needed to bake or unbake the SplineArchitectWall actor. A baked actor will no longer regenerate meshes, and its WallPreset will be locked and unmodifiable until the "UnBake" function is used.

More about baking

  • Bake button bakes this wall
  • UnBake button unbakes this wall
  • Baked boolean cannot be modified; it just shows if this actor is baked or not
  • Bake Method specifies how the actor will be baked: either "Instanced" or "Components". "Instanced" uses InstancedStaticMeshComponent for better rendering performance but harder editing; "Components" uses StaticMeshComponent, easier to edit transforms after baking.

4. Controls

The Controls category contains several functions and parameters to manage this specific SplineArchitectWall actor:

  • CenterActorTransform button centers the actor to the average position of the main SplineComponent spline points.
  • ResetActorTransform button resets the actor’s scale to (1,1,1) and position to the first spline point’s position.
  • BooleansToUse array specifying which SplineArchitectBoolean actors this SplineArchitectWall uses to cut holes in floor or ceiling meshes.
  • Seed specifies the random seed used by this actor when randomization parameters are applied, to avoid similar randomization results among actors.
