Balustrade Modular System

Balustrade Modular System

Build complete balustrade systems directly in the Scene View - no manual prefab placement, no tedious alignment. The Balustrade Modular System is an Editor tool that lets you construct, extend, and modify modular balustrades through a guided, snap-based workflow. Just click, preview, and build.

Prefer to test first? A free LITE version is available - see the link at the bottom.

✨ Key Features

- Scene View Construction:

Build balustrades entirely within the Scene View. Direction arrows guide your placement and a real-time ghost preview shows exactly what will be built before you commit.

- Automatic Placement Validation:

The ghost start pillar automatically detects invalid surfaces - slopes, obstacles, or objects that would prevent proper construction. Invalid placements are visually indicated before you even click. When no surface is detected, the pillar automatically snaps to Y0.

- Continue Build Mode:

Extend any existing balustrade from its end pillars. Select a pillar, pick a direction, and keep building - the system seamlessly connects new segments to your existing structure.

- T-Junctions & Branching:

Build branches from middle pillars (M) and corner pillars (C). The tool automatically replaces the pillar with the correct T-junction piece and lets you continue building in a new direction. Works with both the V1 and the V2 variant.

- Corners & Curved Rails:

90° corners and curved rails are fully integrated into the building workflow. Inner and outer arcs are handled automatically depending on your build direction.

- Close Loop:

Connect the end of a balustrade back to an existing pillar to form a closed circuit. The system detects proximity, highlights the connection in green, and replaces pillars with the correct junction type on commit.

- Inner/Outer Arc Swap:

Select a curved rail and click the button that appears above it in the Scene View to mirror it between inner and outer arc orientation. Neighbouring pillars are automatically replaced (M↔C) and re-oriented. Works with all pillar types and both V1 and V2 variants.

- Variant Switching (V1 ↔ V2):

Switch entire balustrades between two visual variants with a single click. Each variant comes with 4 New and 4 Worn texture sets for maximum visual flexibility. V1 and V2 use different pillar sizes and rail lengths - the system recalculates all positions using topology-aware repositioning to keep everything aligned. Works reliably even when rail segments have been deleted.

- Smart Selection & Deletion:

Clicking a rail automatically co-selects its connected pillars for visual clarity. Shift-click to multi-select rails - pillars between them are highlighted automatically. Delete one or multiple rails in a single action; all affected pillars are repaired automatically.

- Pillar Protection:

Pillars cannot be accidentally deleted. The system intercepts delete commands on pillars to prevent broken balustrades.

- Full Undo/Redo:

Every action - including full Continue Build sessions - is grouped into a single undo step. Ctrl+Z reverts the entire operation, not individual pieces.

- Slope Tolerance:

A built-in 1° slope tolerance ensures balustrades are only placed on flat surfaces, maintaining architectural realism.

- Performance-Friendly:

The entire balustrade uses only 3 materials regardless of length or complexity. Combined with Unity's Static Batching, draw calls stay minimal even in large scenes.

🧱 Pillar Types

The system includes five pillar types that are automatically managed during construction:

- End Pillar (E) - Placed at the start and end of every balustrade segment

- Middle Pillar (M) - Connects two rails in a straight line

- T-Junction Pillar (T) - Connects three rails for branching layouts

- Corner Pillar (C) - 90° connection between two rails

- Corner 45° Pillar (C45) - 45° connection between two rails

🎯 Built for Balustrades

Purpose-built for modular balustrade construction - every feature, from snap logic to automatic pillar type management, is designed around how balustrades actually work in architecture.
