Concept

Turn Text into 3D Worlds

VoxelNovels is a voxel RPG engine built on a fully data-driven architecture,
designed for novelists and scenario writers.

📖

Stories Become Worlds

Generate JSON definitions from your novel or game scenario using AI like ChatGPT. Terrain, buildings, NPC placement, events — everything is expressed purely through data.

🧱

Minecraft Meets MMORPG

A Minecraft-like block world fused with RPG adventure elements. Experience your novel's world as a multiplayer RPG.

🛠

Build Mainly with JSON

Define your world with JSON files such as meta, terrain, objects, npcs, enemies, and events. Map transitions, dialogue, shops, and combat behavior can all be extended through data.

How It Works

Ready in Just 3 Steps

How to turn your story into a playable 3D world.

Prepare Your Story

Use your existing novel or scenario as-is. All you need is your world setting, place names, and character profiles.

Generate JSON with AI

Feed your story to ChatGPT or Gemini to auto-generate JSON (terrain, buildings, NPCs, events) following VoxelNovels specifications.

Deploy & Publish

Just place the generated JSON files in the maps folder. Publish to any web server — anyone can play directly in the browser.

VoxelNovels Script

Game Talk Comic Auto-Player

A universal scenario auto-player that works across every game generated by VoxelNovels.

A New Genre:
"Game Talk Comic"

Game Talk Comic is a new video format where in-game characters carry a story forward with comic-style speech bubbles and voiced dialogue.
Opening titles, subtitles, camera work, and character acting are all auto-played from one JSON scenario.
Characters walk, turn, and speak on cue — the result feels like watching a real movie, exactly the way the script was written.

JSON Scenario + Auto-Direction = A Movie-Like Video, Zero Editing Required

Because the engine drives camera and performance, you can regenerate the same video at the same quality from the same scenario any number of times.
Swap in a new script for instant new episodes, or port the same script across any world and any cast born from VoxelNovels — one talk-comic pipeline for every title.

scenario.json title.show say teleport camera.preset useItem animation subtitle
📜

Fully Automated from JSON

Write one JSON per episode and the engine auto-runs character moves, lines, and camera. Swap the script to instantly ship Episode 2, 3, and beyond on the same set.

🎬

Performance, Camera, Bubbles & Subtitles in One

Conduct teleports, walking, attack animations, camera presets, bubbles, subtitles, and SFX from one file. From a Hollywood-style opening title to a camera-facing outro, the engine performs like a director.

🎥

Capture with OBS, Publish Right Away

A subtle blinking "VoxelNovelsScript" badge in the bottom-right confirms the recording state. Capture in OBS and ship the result to YouTube or TikTok with zero post-edits.

💬

Multi-Character Acts via Multiplayer

The host script directs the host player together with any number of guest characters joined into the party at once. Teleport sync, partner-facing, and audience-facing direction switch automatically, so an ensemble cast of any size performs hands-free — just hit record.

WHY IT'S NEW

Why "Game Talk Comic" Is a Brand-New Genre

Voiced reactions, voice comics, AI machinima, visual novels — many existing video genres share some of these traits.
But no public format has been found that fuses 3D direction × manga-style bubbles × AI voice × subtitles into a single script — and ships in multiple languages just by swapping the language asset.

1

Hybrid Direction

3D characters walk, turn, and speak to the audience — while comic-style bubbles, synthesized voice, and subtitles share the screen at the same time. Not film, not anime: a brand-new visual grammar.

2

Script-Driven

The master source is not an edited timeline — it is an executable JSON scenario. A single AI prompt regenerates the same video at the same quality, any number of times. Re-takes and swaps land in an instant.

3

Multilingual Scalability

One AI prompt swaps the text, voice, and bubbles of a scenario — and instantly ships the episode in any language in the world. Timing tweaks and on-screen-text fixes are auto-corrected by the AI, so the tedious manual editing drops to zero.

UNIQUE SELLING PROPOSITION

One scenario script, plus nothing but a language-asset swap, becomes a fully-acted multilingual 3D video — auto-rendered end-to-end.

Traditional video pipelines require translation → subtitle pass → on-screen text rework → voice swap → re-edit for every locale.
Game Talk Comic's source of truth is executable code, not a frozen timeline, so the marginal cost of going global is near-zero — in theory, the same episode can ship in every language without a single editing pass.

How It Differs From Existing Genres

Voiced Reactions (YMM4 etc.) YMM4 / Voiceroid
Comes close in auto-generating voice and subtitles from a script, but stays 2D-only — no 3D character acting, no manga-style speech bubbles.
Visual Novel Engines Naninovel / Ren'Py
Shares the script and i18n DNA — but stays a game-authoring tool. Almost never used as a video-publishing pipeline.
AI Machinima The Show etc.
Overlaps on auto-3D acting and TTS voice, but follows a cinematic grammar — missing the comic-bubble idiom that defines GTC.
Multilingual Live Streams QSMP etc.
Live-first — nothing is preserved as a finished, replayable work. GTC re-renders the same piece any number of times, in any language.
Web Speech Readers Browser TTS
Same building block (browser TTS), but no one wires it into a 3D-acted, bubble-driven, subtitle-synced, fully-scripted video format.
🌐

Browser-Native TTS, Out of the Box

VoxelNovels Script taps the browser's own SpeechSynthesis API. Multiple Natural voices already ship for English and Japanese, so multilingual voice acting plays without any paid TTS subscription.

🎭

Per-Character Voice Auto-Assignment

Voice timbre, rate, pitch, and pause are all set per character. A priority-list fallback assigns the next available voice when an environment lacks the preferred one — the cast stays consistent across machines.

🌐

One Script, Any Language — Driven by AI

From a single scenario, an AI prompt produces a finished video per language — ready to launch worldwide in parallel.

🏆

Originality: Extremely High

Game Talk Comic merges game engine, manga grammar, automation, and multilingual delivery into a single pipeline — a next-era format for IP creation.
VoxelNovels is powered by an LLM-driven auto-conversion engine: it turns a plain novel document into a playable game, and then turns the characters inside that game into a fully-acted Game Talk Comic — automatically.
Both the source novel and the scenario script can be authored in any language the LLM supports, giving creators a single pipeline that carries any story, in any genre and any culture, straight to a worldwide audience.

For Creators

For Writers & Creators

Turn your work into a 3D game.

Grow Your Novel Fanbase Through 3D Gameplay

Give readers a brand-new entry point: play first, fall in love, then read. Players who have never opened your novel get hooked on the characters and world through gameplay, then move on to become readers. 3D gameplay reaches an audience text alone could never touch.

Design Original Items & Turn Them Into Income

Define your own weapons, armor, items, blueprints, and private invite-only worlds using JSON alone — no programming required. Add original gear and structures, plus exclusive maps reachable only by paying supporters, straight into the game.

Pair that with a creator storefront like fourthwall — the same platform the "❤️ Support the Project" link above uses as a live example — and you can also sell character T-shirts, merch, phone cases, and digital perks on print-on-demand. Fulfillment, payments, and taxes are handled for you, so a single signup + product upload is enough to launch.

The fanbase you build through VoxelNovels becomes a real revenue stream across three axes: in-game items × physical merch × exclusive worlds — a sustainable income channel for the author.

Expand the Game with JSON-first Workflow

VoxelNovels is built on a fully data-driven architecture.
Terrain, buildings, NPC placement, events, shops, and map transitions —
every element of the game world is defined through JSON files.

Your Story + AI + JSON = A Playable 3D World

Simply feed your novel and the VoxelNovels spec to AI like ChatGPT or Gemini,
and the required JSON data is generated automatically.
Create 3D models for main characters using tools like Tripo or Meshy.
Generic NPCs (townspeople, monsters, etc.) are included in the system.
For BGM production, you can also use external tools such as Suno and assign tracks by world or area.

"No-Code" Doesn't Mean
Easy 3D Online Games

"No-code" sounds like magic — as if anyone can create a game instantly.
The reality is "you're not typing code, but you're still programming in your head."
Especially for 3D online RPGs, the barrier is far from low.

Roblox Studio Luau

World's largest platform. Templates and AI assist exist, but logic setup is essential for real gameplay.

RPG Developer BAKIN EVENT PANEL

Japan-made 3D RPG tool. Map creation is intuitive, but complex quests and battles require logical assembly.

YAHAHA METAVERSE

Build multiplayer spaces with drag-and-drop, but RPG flag management must be handled manually.

GDevelop EVENT SYSTEM

Open-source event-based tool. Has online sync, but requires network knowledge to use effectively.

RPG Maker EVENT COMMAND

The classic RPG creation tool. Event commands handle dialogue and battles, but it's 2D-focused with no online support. Advanced effects require scripting knowledge.

Unreal Blueprints VISUAL SCRIPT

Top-tier 3D engine. Node-based visual scripting, but requires the same logic as professional coding.

Why It's Not "Easy for Anyone" — 3 Invisible Walls

1 No "syntax" needed, but "logic" is mandatory

You don't write if-statements, but you must set up each condition one by one through UI. Attack detection, invincibility states, HP management — building logic chains is programming itself.

2 The maze of "variables" and "flags"

"Talked to the chief" AND "has 3 herbs" opens the door — you must manage all these variables and switches yourself, or the game won't function at all.

3 The "synchronization" challenge unique to online games

Matching screens across players requires network design knowledge — what data to send, what to sync. Without it, you get jittery movement and item duplication bugs.

TEXT-FIRST WORKFLOW

VoxelNovels Approach:
Text-First 3D Game Generation

VoxelNovels focuses on a workflow that makes it easier to build game data from your story.
You can generate a JSON draft with AI and then apply only the adjustments you need,
implementing branching, flag management, and multiplayer sync step by step.

Other No-Code Tools
  • Logical thinking required
  • Manage variables/flags yourself
  • Network sync knowledge needed
  • UI feels like a giant cockpit
VoxelNovels
  • Build from your story first
  • AI assists JSON draft generation
  • Built-in multiplayer sync foundation
  • Publish & play instantly in browser
