Stage Programmatic Objects

Applies to SuperStage 26H2.5 and later ｜ Read first: Stage Assets Overview

This document covers the seven programmatic objects added in 26H2.5. Like the trusses and scaffolds, they are parametrically generated and rebuild when a parameter changes.

To place one: the StageModel category in the asset browser, or search by name in the Place Actors panel.

Object	In one line	Driven by
Super Barrier	Crowd barrier / crowd-control fence / site fence	Spline
Super Stage Roof	Stage roof system	Parameters
Super Grandstand	Tiered grandstand	Parameters
Super Stair Tower	Stair tower	Parameters
Super Trackway	Ground panels / trackway	Spline
Super Cable Run	Cable routing	Spline
Super Ballast	Ballast layout	Parameters

⚠️ As with the other structural assets: the weight, load, ballast and sightline figures these objects report are reference estimates from simplified models, for order-of-magnitude reference and statistics during previs. They are not structural-safety conclusions and cannot replace structural design, mechanical verification or construction safety approval.

1. Super Barrier

Spline-driven. Lays a run of barrier panels along the spline.

Group	Parameters
Type	Barrier Type (front-of-stage / crowd-control / site fence), Infill Mode
Dimensions	Panel Width, Panel Height, Foot Depth, Panel Gap, Post Diameter, Rail Diameter, Infill Bar Count, Mesh Wire Rows
Layout	Foot Side, Lateral Offset, Start Offset, Gap Panel Indices
Ground Snap	Snap to Ground, Ground Collision Channel, Raycast Start Height, Raycast Depth, Default Ground Height, Ground Offset, Align To Ground Normal
Visibility	Show Posts / Rails / Infill / Feet / Braces
Material	Frame / Infill / Foot

Key points:

• Gap Panel Indices opens gateways — name the panel indices to leave out, rather than cutting the spline;
• Foot Side decides whether the feet face the audience or the stage, which matters on a front-of-stage barrier;
• With Snap to Ground on, the barrier follows the terrain; add Align To Ground Normal to let the panels lean with the slope.

2. Super Stage Roof

Parameter-driven. Generates a stage roof system with corner towers.

Group	Parameters
Main	Roof Shape (flat / gable / arch), Span, Depth, Clear Height, Roof Rise
Profile	Tower Section, Truss Size, Brace Pattern, Rib Count, Rib Segments, Tower Bays
Extras	Show PA Wings, PA Wing Reach / Depth / Taper / Hang Points, Show Backdrop Frame, Backdrop Mullion Count
Skin	Show Roof Skin, Skin Thickness, Skin Overhang
Load	Suspended Load, Design Wind Speed
Visibility	Show Towers / Purlins / Base Plates
Material	Chord / Brace / Skin / Base Plate

Key points:

• Clear Height is the clear height from the ground to the underside of the roof; Roof Rise is the rise of the roof itself. They are separate;
• PA Wings are the side wings that carry the sound system; PA Wing Hang Points gives the number of hang points;
• Design Wind Speed feeds the statistics only. It is not a wind-load certification.

3. Super Grandstand

Parameter-driven. Tiered seating with automatic aisle splitting and a sightline readout.

Group	Parameters
Seating	Row Count, Seats Per Row, Seat Width, Row Depth, Row Rise
Aisle	Enable Aisles, Seats Per Block, Aisle Width
Sightline	Focus Distance, Eye Height
Structure	Deck Thickness, Post Diameter, Rail Diameter, Post Every N Rows, Post Spacing X
Visibility	Show Riser Boards, Show Railing, Railing Height, Show Front Guardrail, Show Seat Markers, Show Support Frame
Material	Deck / Tube / Seat Marker

Key points:

• With Enable Aisles on, each row is split into blocks of Seats Per Block with an Aisle Width gangway between them;
• The sightline clearance is computed from Focus Distance (the point on stage being watched) and Eye Height (seated eye height). It is a previs reference, not a compliance judgement against a sightline design code;
• Row Rise is the step-up per row and directly decides whether the back rows can see over the front.

4. Super Stair Tower

Parameter-driven. Single-flight or double-return.

Group	Parameters
Main	Flight Mode (single / double-return), Total Height, Target Riser, Going, Steps Per Flight
Dimensions	Flight Width, Lane Gap, Platform Depth, Tread Thickness, Post Diameter, Rail Diameter, Ledger Spacing
Railing	Show Railing, Railing Height, Mid Rail Count
Visibility	Show Diagonals, Show Base Plates
Material	Tube / Deck / Base Plate

Key points:

• Target Riser is a target, not the final value — the total height is rounded to a whole number of steps, so the actual riser differs slightly. The panel shows the resulting step and slope figures;
• Going is the tread depth. The riser-to-going ratio decides whether the stair is comfortable;
• In double-return mode Lane Gap is the gap between the two flights and Platform Depth is the depth of the turn landing.

---

5. Super Trackway

Spline-driven. Lays ground panels along the spline, several lanes side by side.

Group	Parameters
Spec	Panel Type
Dimensions	Panel Length, Panel Width, Panel Thickness, Lane Count, Panel Gap, Lane Gap
Layout	Stagger Joints, Lateral Offset, Start Offset
Ground Snap	Same set as Barrier
Material	Panel

Key points:

• With Stagger Joints on, adjacent lanes are offset so the joints do not line up in a straight run;
• Lane Count is how many lanes side by side; Lane Gap is the gap between them;
• Can conform to terrain.

---

6. Super Cable Run

Spline-driven. Two laying modes.

Group	Parameters
Route	Route Mode (suspended sag / ground ramp), Support Spacing, Sag Ratio, Segments Per Span
Cable	Cable Count, Cable Diameter, Cable Spacing, Weight Per Meter, Vary Sag Per Cable
Support	Show Supports, Support Size, Ramp Width, Ramp Height, Ramp Section Length
Material	Cable / Support

Key points:

• In suspended mode, Sag Ratio controls the droop and Support Spacing the distance between supports — together they decide how the cable hangs;
• With Vary Sag Per Cable on, each cable droops slightly differently, which reads more naturally than a uniform bundle;
• In ground mode the cables are covered by ramps; Ramp Width / Height / Section Length are the ramp dimensions;
• Weight Per Meter feeds the weight statistics only.

---

7. Super Ballast

Parameter-driven. Lays out ballast blocks, and can work back from an entered overturning moment to the mass required.

Group	Parameters
Spec	Block Type, Layout
Layout	Count X, Count Y, Layer Count, Block Gap, Centered
Dimensions	Block Length, Block Width, Block Height, Block Weight
Requirement	Compute Required Mass, Overturning Moment, Lever Arm, Safety Factor
Material	Block

Key points:

• With Compute Required Mass on, enter the Overturning Moment (kN·m), Lever Arm (m) and Safety Factor, and the panel reports the mass required;
• That figure is an order-of-magnitude reference from a simplified formula. ⚠️ It is not an overturning-resistance verification and must not be used as the basis for an on-site ballast plan. Real overturning resistance must be calculated by a qualified structural engineer for the actual load cases;
• Layer Count is how many layers to stack; Centered decides whether the array is centred on the Actor origin or extends from it.

8. General Notes

Spline editing: Barrier, Trackway and Cable Run are spline-driven. Select the Actor and drag the spline control points in the viewport; right-click a point to add or remove one.

Ground conformity: Barrier and Trackway support Snap to Ground. It traces downward on a collision channel, so the terrain must have collision.

Statistics: each object provides read-only part counts and weight estimates. The data is for previsualisation reference only.

Scene complexity: these objects all render with instanced static meshes. Pushed to large values (several hundred panels across several lanes, for example) the part count grows quickly — confirm the layout at a smaller scale first.
