Box
The Box is the general blockout solid and the only shape that owns the hollow-room workflow.
Exclusive parameters
- Is Hollow creates a room/container form instead of a solid block.
- Hollow Thickness controls wall thickness around the interior.
- Inner Floor Height raises only the hollow interior floor so shallow boxes keep visible inner side walls.

- The face API exposes the six outer faces plus the hollow inner floor when hollow is enabled.
Use it when: use it for rooms, covers, platforms, blockout masses, hollow pits, and quick face-drag prototyping.
Wall
The Wall is a purpose-built partition actor with length, height, thickness, and opening arrays.
Exclusive parameters

- Door Openings create zero-sill cutouts using Center X, Width, Height, and Bottom Height.
- Window Openings use the same struct but keep a sill height.

- Snap points sit on the wall ends so wall segments connect end-to-end.
Use it when: use it for room walls, hallway blockers, cover partitions, window prototypes, and doorway planning.
Floor / Platform
The Floor actor is a horizontal slab optimized for playable surfaces, holes, borders, and editable top cells.
Exclusive parameters

Wedge / Ramp
The Wedge is a triangular-prism ramp with optional slope direction changes.
Exclusive parameters
- Flip Slope reverses the high and low ends of the ramp.

Use it when: use it for pillars, drums, round platforms, circular vents, ringed pads, and simple path tubes.
Cone
The Cone inherits the radial cylinder base but exposes cone-focused size and orientation controls.
Exclusive parameters
- Cone Radius, Cone Height, Cone Sides, Cone Height Segments, and Cone Cap Radial Segments are the visible cone controls.
- Flip Vertically points the tip in the opposite direction along the active axis without turning the mesh inside-out.
- Flip Horizontally lays the cone along the local X axis instead of local Z.
- The tip is selectable in face editing so dragging it changes size along the tip direction.
Use it when: use it for markers, spikes, arrows, roof cones, hazards, and directional prototypes.
Sphere
The Sphere is a smooth round primitive that can become a dome/hemisphere.
Exclusive parameters
- Radius controls the whole shape.
- Rings and Segments control latitude and longitude tessellation.
- Is Hemisphere builds only the top dome and adds a flat bottom face.
- Normals are generated smooth automatically; there is no Smooth Normals parameter.
Use it when: use it for domes, collision markers, round props, arena volumes, and soft placeholder masses.
Column / Pillar
The Column combines a shaft with optional base and capital so structural pillars do not need stacked actors.
Exclusive parameters
- Shaft Radius, Column Height, and Sides define the central post.
- Has Base reveals Base Radius and Base Height.
- Has Capital reveals Capital Radius and Capital Height.
- The face API exposes top, bottom, and side/radius edits.
Use it when: use it for structural supports, decorative pillars, cover posts, ruins, and modular architecture blocking.
Pipe / Tube
The Pipe is a dedicated hollow tube actor. It overlaps with Cylinder inner-gap use, but keeps pipe-specific wall and cap controls.
Exclusive parameters
- Outer Radius and Pipe Thickness define the outer wall and inner radius directly.
- Pipe Length and Horizontal choose vertical or horizontal orientation.
- Capped Ends seals the tube when a closed pipe is needed.
- Use Separate Cap Material enables a cap material slot independent from side walls.
- Face Material Overrides and Assign/Clear Material Override functions support face-level material assignment.
- Path Points can build a multi-segment tube.
Use it when: use it when pipe wall thickness, capped ends, or pipe-specific face materials matter more than cylinder cap rings.
Arch
The Arch creates an archway or tunnel segment from radius, wall thickness, depth, and leg height.
Exclusive parameters
- Inner Radius and Wall Thickness define the opening and surrounding shell.
- Arc Angle supports partial arcs through full circular arcs.
- Segments controls curve smoothness.
- Leg Height adds vertical supports below the curved part.
- Editable faces include front, back, top, and inner floor.
Use it when: use it for door arches, tunnels, sewer mouths, bridges, vaulted openings, and curved cover.
Stairs
Stairs are procedural-only and cover straight runs, spiral stairs, and circular platforms.
Exclusive parameters
- Stair Shape switches between Linear, Spiral, and Circular Platforms.
- Linear Type chooses Open, Closed, or Box underside treatment.
- Spiral Inner/Outer Radius, Step Angle, Counter-Clockwise, Radial Segments, and Column Radius shape spiral and helix stairs.
- Circular Platform Radius, Radius Reduction Per Step, and Platform Sides build stacked round platforms.
- Side Bar and Balustrade controls add stringers, posts, custom baluster meshes, and optional handrails.
- Stairs snap at the bottom-front and top-back so flights can stack vertically.
Use it when: use it for traversal tests, vertical metrics, arena tiers, spiral towers, and blocked-out railings.
L-Shape
The L-Shape creates two perpendicular wings as one procedural actor.
Exclusive parameters
- Wing A Length controls the local +X wing.
- Wing B Length controls the local +Y wing.
- Wall Width is the shared corridor/arm width.
- L Height controls the vertical extrusion of both wings.
Use it when: use it for corner rooms, L corridors, wrapped cover blocks, and footprints that should resize as one piece.
Polygon
The Polygon builds an N-sided filled or hollow planar/prism shape.
Exclusive parameters
- Radius controls the circumradius.
- Thickness extrudes the polygon; zero leaves it flat.
- Sides changes the footprint from triangle to high-sided round-like forms.
- Cap Filled toggles between a filled polygon and border-only ring.
- Border Thickness controls the ring width when Cap Filled is off.
Use it when: use it for custom pads, trims, hex platforms, floor symbols, border rings, and stylized footprint blocks.
Door
The Door is a runtime-capable hinged panel, not just a static blockout mesh.
Exclusive parameters
- Door Width, Height, and Thickness scale the panel.
- Pivot X and Pivot Y place the hinge anywhere across the door footprint.
- Open Angle, Swing Direction, Play Rate, and Start Open control animation behavior.
- Door Mesh accepts a custom static mesh/material setup.
- Set Door Open and Toggle Door are callable at runtime.
Use it when: use it for interactive door planning, hinge clearance checks, and Blueprint-ready placeholder doors.
Ladder
The Ladder is separate from Stairs and builds rails plus rungs with climb support hooks.
Exclusive parameters
- Ladder Height and Ladder Width define the climbable frame.
- Rail Thickness and Rung Thickness control the geometry thickness.
- Rung Count and End Rung Inset distribute rungs between the rail ends.
- Top and bottom snap points make stacked ladder layouts easy.
- The runtime tick can track a climbing character in the ladder zone.
Use it when: use it for vertical traversal prototypes where a stair shape would be the wrong gameplay read.
Barrel
The Barrel actor generates a bulged prop-like form with separate body, cap, and hoop sections.
Exclusive parameters
- End Radius, Bulge Depth, Height, Sides, and Height Segments define the barrel body.
- Stave Count and Stave Groove Depth create vertical wooden grooves.
- Hoop Count, Hoop Width, Hoop Depth, and Hoop Inset create metal bands.
