Kadajah UltraD - True HD 2D Maps & Real-Time Engine 

Step out of the flat 2D grid. Build immersive, atmospheric worlds directly inside RPG Maker MZ.

Traditional RPG Maker maps are flat, bounded by strict two-dimensional layers. Kadajah UltraD shatters the ceiling, transforming your RPG Maker MZ project into a fully rendered, true 3D environment powered by the Three.js engine.

Build towering cities, deep dungeons with sunken pits, and atmospheric forests without ever leaving the MZ editor. With dynamic 3D point-lights, high-resolution building facades, and billboarded sprites that retain your classic retro charm, you can now deliver a stunning HD-2D or classic 3D-retro aesthetic with zero coding required.

v4.5 Update: Added custom camera distance and angle parameters, along with "Secure Fade-In" loading to ensure maps and cameras settle completely before fading in, eliminating visual popping.

v4.8 Update: Introduced sunken terrain mechanics (Region IDs 10 to 13) for creating riverbeds, trenches, and lower floors, plus automated texture animations for water and waterfalls.

v5.0 Update: Complete architecture overhaul featuring the Live Map Watcher (Real-Time Editor), Dynamic Point-Light systems (Player, Event, and Ambient lighting), and High-Res Facade overlays with side-rendering support.

Key Features

• True 3D Voxel Architecture: Use Region IDs (1 to 9) to effortlessly stack tiles vertically and build walls, pillars, and towering structures. Use Region IDs 10 to 13 to carve out sunken pits, trenches, and water beds (-0.2 to -0.5 blocks deep).
• Dynamic 3D Lighting Engine: Take complete control over your atmosphere. Set global Ambient Light, attach an adjustable Lantern/Point Light to the player, or turn any event into a glowing torch, magical crystal, or streetlamp using simple notetags (<light: #ffaa00, 1.5, 5.0>).
• Smart Fence & Wall Auto-Connecting: The engine automatically detects B-E tileset connections. Fences and thin walls automatically orient horizontally, vertically, or create corner intersections based on surrounding tiles.
• 3D Weather & Atmosphere: RPG Maker's default Rain, Storm, and Snow are dynamically converted into 3D particle systems that fall through the Z-axis in real-time, complete with depth fog and screen tint synchronization.
• Advanced Event & Sprite Manipulation:
  • Layering (<L1> to <L9>): Place birds flying high in the sky, floating chests, or NPCs standing on second-story balconies.
  • Doors (<door>): Stick event graphics flat against 3D block faces for seamless, realistic doorways.
  • Billboarding & Fixed (<fixed>): Keep retro sprites naturally facing the camera, or lock their rotation in 3D space for architectural objects.
  • Scaling & Offsets: Fine-tune event positions (<offsetX/Y/Z>) and scale (<scale: 1.5>) down to the decimal.

The Workflow: Real-Time Live Editor & Facades

Stop guessing how your 3D map looks. Build and iterate in real-time.

• Live Map Watcher: When running your game in test mode (NW.js), the engine actively monitors your project's JSON files. Simply save your map in RPG Maker MZ, and the 3D game window instantly reloads and rebuilds the geometry in milliseconds, no restarting required!
• The Facade System: Don't limit your buildings to repeating 48x48 tiles. The Create Facade plugin command allows you to take any high-resolution image from your pictures folder and overlay it directly onto the front and sides of your 3D voxel stacks. Build custom storefronts, detailed castle gates, or HD-2D background wallpapers effortlessly.

Creative Gameplay Mechanics

• HD-2D & Retro 3D Aesthetics: Combine classic pixel-art characters with dynamic 3D lighting, depth fog, and custom screen colors (SetScreenColor) to recreate the feel of modern retro masterpieces.

• Atmospheric Stealth & Horror: Strip away global ambient light, wrap the world in pitch-black fog, and force the player to rely entirely on a short-range lantern to navigate terrifying 3D labyrinths where monsters lurk in the shadows.

Perfect Game Examples

• 3D Dungeon Crawlers & Labyrinths: Perfect for angled top-down or isometric dungeon exploration with claustrophobic walls and glowing torches.
• Atmospheric Horror Games: Leverage the dynamic fog, custom screen lighting, and localized event point-lights to build terrifying, shadow-drenched environments.
• Modern HD-2D JRPGs: Elevate a standard top-down RPG into a visually stunning isometric/3D world without needing to learn Unity or Unreal Engine.

Compatibility & Requirements

• Engine: RPG Maker MZ.
• Platforms: Windows, macOS, Linux, and Web Browsers (requires WebGL support).
• Dependencies: Automatically loads Three.js (r128) seamlessly in the background.

Technical Specs & Plugin Compatibility

Built for stability. Designed to play nice.

The Kadajah UltraD engine uses non-destructive Method Aliasing for its core hooks. It operates as a high-performance WebGL rendering layer over the standard tilemap without breaking underlying RPG Maker collision, passability, or event logic.

Modified Classes: The plugin safely extends the following core classes:

• Game_Map: Adds 3D facade tracking, lighting variables, and the Node.js live-update file watcher.
• Scene_Map: Handles Three.js world generation, camera mathematical tracking, weather conversion, lighting updates, and sprite billboarding.
• Sprite_Animation & Sprite_AnimationMV: Automatically projects 3D world coordinates back to 2D screen space, ensuring your standard RPG Maker spell and battle animations play at the exact correct screen position over 3D events!
• Game_CharacterBase: Hooks into canPass to ensure 3D wall collisions respect tilemap passability flags.

Performance & Memory: Optimized with intelligent texture caching, matrix auto-update disabling for static voxels, and custom canvas-texture extraction for autotiles and animated water.
