✨ Key Features & Capabilities

Interactive Video Triggers: Assign any .webm video to individual grid zones. When a unit rolls or moves onto a space, it triggers a fullscreen or overlay video event (simply click anywhere to dismiss). Set spaces to null for regular movement without triggers.
Dynamic Stat Parsing: Use a fast, standardized syntax to automatically load character parameters directly into the UI: [name]_[action]_[atk]_[def]_[ext].
Distance & Line of Sight (LoS): Built-in measurement tools with toggleable distance metering and modular default terrain to test cover and line-of-sight mechanics.
Integrated Dice Rolling: Built-in dice system to immediately resolve combat, movement, and event checks.
Bring Your Own Assets: Easily load your own custom .glb 3D models, board textures, and video assets. (Check the download section below for starter files and templates!)

3D Miniature Tabletop Sandbox (v6.12)

User Manual & End-User License Agreement (EULA)

Studio Takuetsu, LLC

Part 1: Comprehensive User Manual

1. Overview & Architecture

3D Miniature Tabletop Sandbox (v6.12) is a browser-based, client-side virtual tabletop (VTT) engineered with Babylon.js, Tailwind CSS, and PeerJS. It enables tabletop roleplayers, wargamers, and card game designers to stage tactical board scenarios in 3D using custom 3D models (>span class="s2">.glb/.gltf), 2D billboard standees (.png/.jpg), dynamic animated WebM cutscenes, and real-time WebRTC peer-to-peer multiplayer.

2. Top Navigation Bar Controls

Control	Description
Sidebar Toggle (☰)	Expands or collapses the left configuration sidebar.
P2P Multiplayer	Host a session to generate a 4-character room code, or join an active room code via WebRTC.
Camera Reset (🎥)	Returns the camera to default orbit coordinates (0, 24, -20) targeting scene origin (0,0,0).
Fullscreen (⛶)	Toggles browser fullscreen mode.
Fog of War (🌫️)	Enables dynamic visibility calculations (reveals tiles within a 6.0-unit radius of miniatures).
Ruler Tool (📏)	Measures exact board distances between two clicked points in grid tile units.
Line of Sight / LoS (👁️)	Raycasts between two points to check for line-of-sight obstruction against walls/pillars.
3D Dice Engine (🎲)	Procedural 3D physics-style animated roller for D4, D6, D8, D12, and D20 dice with audio feedback.
LP Trackers (P1 / P2)	Health/Life point trackers with quick +500 and -500 increments.
Turn & Phase Tracker	Steps through game phases (Draw Phase $\to$ Main Phase 1 $\to$ Battle Phase $\to$ Main Phase 2 $\to$ End Phase).
Save / Load State (💾 / 📂)	Exports or imports the entire board layout, unit positions, stats, and lighting configuration to a single .json file.

3. Left Sidebar Toolsets

Board Customizer & Scale

Grid Size Radius: Dynamically scales the arena from Small (5×5) up to Epic (11×11).
Floor Texture Upload: Ingest custom battlemaps or top-down backdrop illustrations onto the ground plane.
Hide Tile Opacity: Toggles tile surface visibility to display underlying battlemaps without disabling zone triggers.

Lighting & Glare Controls

Light Intensity Slider (0.2 – 3.0): Adjusts key directional illumination and shadow casting.
Ambient Fill Slider (0.1 – 2.0): Tunes hemispheric ambient light fill levels.

Status Tokens & 3D Terrain Props

Tokens: Instant one-click spawners for Poison, Stun, Fire, and Shield status markers.
3D Props: Spawns collidable tactical cover objects (Wall, Pillar, Crate, Platform) that interact with the Line of Sight raytracer.

Asset Ingestion & Figure Text Importer

Files & Folders: Batch import .glb, .gltf, .png, .jpg, and .webm clips directly via disk selection or drag-and-drop.
Filename Parsing: Automatically extracts stats and triggers from standard naming schemas (e.g., Dragon_atk180_def120_mana5_strike.glb).
Decklist Text Importer: Rapidly instantiate units using line-by-line quantities (e.g., 3x Paladin_atk120_def150.glb).

4. Interactive Miniature Controls & Hotkeys

Miniatures can be moved across the grid via click-and-drag. Moving a unit over a configured tile automatically evaluates tactical event triggers and triggers matching WebM cutscenes.

Input / Shortcut	Action
Left Click (Unit)	Selects unit and opens detailed stat/animation inspector in the sidebar.
Left Click (Tile)	Selects tile to configure trigger IDs, video aliases, decals, and colors.
R	Rotates selected miniature by +90°.
S	Snaps elevated miniature flush back to the floor plane (Y = 0.2).
E / Q	Raises or lowers miniature elevation by +0.5 / -0.5 units.
HUD Toggle	Displays overhead billboard badges showing unit name, active status effects, and HP bars.
