In the Viva Project (also known as OpenViva), character cards are essential PNG files that store custom AI anime models, outfits, and skins for use in the simulation. Installation Guide
To use a new character or outfit, follow these steps to place the files in the correct game directory:
Characters: Download both the Character card (blue) and the Skin card (yellow). Place them in: [Viva Game Folder]/Cards/Characters [Viva Game Folder]/Cards/Skins Outfits/Clothing: Move the standalone outfit .png file to: [Viva Game Folder]/Cards/Clothes.
Activation: Once files are placed, access the character customizer in-game through the bedroom mirror to load your new model. Technical Specifications for Creators
If you are developing your own cards using the Blender Viva Model exporter addon, ensure your model meets these performance limits: Polygon Count: Maximum 65,536 triangles. Rigging: Maximum 255 bones and 4 weights per vertex. Materials: Strictly 3 materials (1 for skin, 2 for pupils).
Image Format: Cards must be 1024x1536 pixels in PNG format to be recognized by the game. Resource Links

Viva Project —an ambitious leap in the realm of AI-driven simulation—has redefined how we perceive digital companionship. At the heart of this experience lies the Character Card
, a modular blueprint that serves as the "DNA" for the game’s artificial intelligence. Far from being a mere static profile, these cards represent a sophisticated blend of personality scripting, behavioral logic, and aesthetic identity. The Anatomy of a Soul
A Character Card in Viva is more than a list of traits; it is a framework for emergent behavior. Unlike traditional NPCs (Non-Player Characters) that rely on rigid dialogue trees, Viva’s characters use their cards to interpret the world around them. The card dictates three primary layers: Core Personality:
This defines the "who." Is the character shy, boisterous, cynical, or nurturing? These base settings act as a filter through which every player interaction is processed. The Memory Bank:
Cards allow characters to retain information about the player’s past actions. If you consistently bring a character their favorite snack, the card updates to foster a sense of gratitude and familiarity, making the relationship feel earned rather than programmed. Physical Expression:
The card links personality to animation. A "clumsy" trait on a card doesn't just change text—it changes how the character walks, reaches for objects, and reacts to physical obstacles in the environment. The Power of the Community
What makes Viva Project Character Cards truly "viva" (alive) is the democratization of their creation. By allowing users to script and share their own cards, the project has turned into a massive laboratory for social AI.
Creators experiment with complex archetypes—from stoic guardians to chaotic pranksters—pushing the boundaries of how much "humanity" can be packed into a file. This community-driven evolution ensures that the characters are constantly learning from a diverse range of human temperaments, leading to interactions that are often surprising, poignant, or hilariously unpredictable. The "Uncanny Valley" and Beyond
The brilliance of the Character Card system is how it bridges the "uncanny valley." By focusing on consistent behavior
rather than just photorealistic graphics, the Viva Project makes its characters feel real through their agency. When a character refuses to follow a command because their "Independent" trait is high, it creates a moment of genuine friction that mimics real-world social dynamics. Conclusion
Viva Project Character Cards are a glimpse into the future of interactive media. They transform the player from a passive observer into a participant in a living ecosystem. As these cards become more nuanced, the line between "code" and "character" continues to blur, proving that in the digital age, a soul can indeed be scripted—one card at a time. or learn more about the technical scripting behind their logic?
Here’s a helpful post tailored for teachers, facilitators, or students using Viva Project Character Cards (often part of social-emotional learning, literature analysis, or history role-play).
If you are stuck in the “sagging middle” of your manuscript, pull out your protagonist’s Catalyst Card and their Arc Card. If the distance between them is too short, add a new Shadow Card—a new lie the character must unlearn—and write a chapter that forces them to confront it. Viva Project Character Cards
The Viva Project Character Cards represent a paradigm shift from static role-play tokens to dynamic psychological engines. By anchoring every mechanic in narrative tension (DT), relational bonds, and meaningful sacrifice (Willpower cost), the system produces outcomes that are both emotionally authentic and analytically valuable.

Viva Project (and its successor Character Cards are image files (.png) that store the 3D model, textures, and settings for your AI companions. Developing content for these cards involves creating or downloading specific assets to customize the characters' appearance in the game's VR or PC environment. 1. Types of Content Cards
The game's customization system relies on two primary types of cards that must be used together: Character Cards (Blue): These contain the main 3D model data for the character. Skin Cards (Yellow):
These store the specific textures, skin tones, and facial details for the model. Clothing Cards:
Separate image files used to swap individual outfits like school uniforms or casual wear. 2. How to Develop and Install Content
If you are looking to create or add new characters, follow these methods: Creating Your Own (Advanced): Tools Required: Viva Model exporter addon Technical Limits: Models must not exceed 65,536 triangles
, 255 bones, and 3 materials (one for skin, two for pupils). Port a 3D model and export it as a
file. Adding facial animations can take between 20 minutes and 2 hours. Downloading Community Content: Official repositories like the OpenViva Assets Page #character-cards
channel in their Discord are the primary sources for pre-made cards. Installation Steps: Character Cards /Cards/Characters Skin Cards /Cards/Skins Clothing Cards /Cards/Clothes Access them in-game via the character customizer found at the bedroom mirror or the onsen (hot spring). 3. Content Guidelines The community-driven OpenViva Reddit and developer platforms emphasize wholesome interactions
. While custom models are encouraged, creators are often restricted from sharing extremely lewd or inappropriate attire to maintain the project's original "take care of a digital friend" vibe. If you'd like, I can help you: OpenViva - Mods & Cards
This paper outlines the technical and community-driven framework of Character Cards Viva Project , an advanced AI interaction simulator
. In this ecosystem, character cards serve as modular data containers that allow players to import, customize, and share unique AI companions.
Paper: Modularity and Customization in AI Simulations—The Viva Project Character Card System 1. Introduction Viva Project
is a virtual interaction simulation—compatible with both VR and standard displays—centered on dynamic engagement with AI anime characters. A core pillar of its replayability and community growth is the Character Card
system, which allows for the seamless integration of custom-built 3D models and behavioral profiles into the game engine. 2. Technical Composition of Character Cards Rather than a single file, a "Character Card" in Viva Project
typically consists of two primary image-based components that act as data carriers: Character Card (Blue Card):
Contains the primary 3D mesh data and identification metadata. Skin Card (Yellow Card):
Houses the texture and shader information for the model's appearance. Clothing Cards: In the Viva Project (also known as OpenViva
Optional additional cards used to modify the character's outfit. These files are typically stored as images, using steganography
to hide complex model data within the image pixels. This allows the cards to be easily shared on image boards and Discord servers while remaining functional assets for the OpenViva Assets Portal 3. Development and Integration Workflow
The creation of these cards involves a specific technical pipeline to ensure compatibility with the game’s inverse kinematics and animation systems: 3D Modeling:
Models are typically created in Blender and must adhere to technical limits: a maximum of 65,536 triangles , 255 bones, and specific material counts. Exporter Add-on: Developers use the Blender Viva Model exporter to convert 3D models into the format required for card generation. Facial Animation:
Creators spend significant time (20 minutes to 2 hours) configuring facial animations and eye tracking to leverage the game's library of over 200 animations. 4. Interaction and AI Behavior
Once a card is loaded via the in-game character customizer (located at the bedroom mirror), the AI takes control. The character cards interface with a dynamic mood system that responds to player actions such as: Feeding and Gifting: Affects the character's immediate emotional state. Environmental Interaction:
Characters can swim in hot springs, play minigames, or complete tasks with the player. Inverse Kinematics:
The AI uses sophisticated physics to react physically to being touched or moved. 5. Community Impact and Open Source Evolution The original Project Viva
development was discontinued in 2022, but the system survives through
, a community-led continuation. The character card format has created a decentralized marketplace of content where creators can upload verified cards to OpenViva - Mods & Cards 6. Conclusion
Character cards represent a significant shift in how user-generated content is handled in simulation games. By consolidating complex 3D assets into portable, shareable "cards," Viva Project
lowered the barrier for community participation and ensured the longevity of the simulation through a constant influx of new, player-created personalities. for creating your own card or find the latest community-made characters Viva Project for Android - Download 20 Jan 2026 —

In the Viva Project (also known simply as Viva or OpenViva), Character Cards are essential portable data files that allow you to import, share, and customize AI-driven anime companions within the game. These cards act as "containers" for the character's 3D model, textures, and behavioral data. What are Character Cards?
Character Cards are typically .png image files that contain embedded metadata used by the game engine to reconstruct a specific character.
Character Card (Blue): Often refers to the base model file that defines the character's shape and structure.
Skin Card (Yellow): Contains the specific textures and colors applied to the model.
Clothing Cards: Separate cards used to swap outfits and accessories for your AI companion. Core Features
Advanced AI: Characters imported via cards can interact with the environment, react to your actions through over 200 animations, and have dynamic moods.
Customization: Users can create their own cards using the Blender Viva Model exporter to port 3D models into the game.
Community Sharing: Players frequently share pre-made cards for popular characters like Shinobu, Astolfo, Kyaru, and Cirno on the OpenViva Assets page or the community Discord. How to Install Character Cards For Novelists Facing Writer’s Block If you are
To add new characters to your game, follow these general steps:
Download: Obtain the character and skin cards (full-size .png files) from community sites like OpenViva.
Locate Folders: Navigate to your game's installation directory and find the Cards folder. Place Files: Move character files into Cards/Characters. Move skin files into Cards/Skins. Move clothing files into Cards/Clothes.
Access In-Game: Open the character customizer (typically found at the bedroom mirror) to select and apply your new character. Technical Requirements for Creators
If you are designing your own Character Cards, the game imposes specific technical limits to maintain performance: Triangles: Maximum 65,536. Bones: Maximum 255. Materials: Maximum 3 (1 for skin, 2 for pupils). OpenViva - Mods & Cards - Viva Project
In the context of the game Viva Project , "character cards" typically refer to digital files (often .png images) used to import custom AI anime characters into the simulation. If you are looking to prepare a "paper" version or a physical guide for these, you are likely looking for a way to print and organize your digital card collection or create a DIY physical reference. Digital Character Cards
Character cards are the backbone of customization in Viva Project. They contain character data embedded in image files.
Storage Location: On PC, these cards are typically placed in the Cards/Characters folder within the game directory.
Obtaining Cards: You can download new characters from the OpenViva Mods & Cards gallery or community hubs like Discord.
Visuals: High-quality cards are often shared as full-size .png files; thumbnails should be avoided as they may not contain the necessary metadata for the game to read the character. Preparing a Physical "Paper" Collection
If you want to create a physical binder or "paper" version of your Viva character library, follow these steps:
Select Your Cards: Browse your Cards/Characters folder and identify the characters you use most frequently.
Print for Reference: Use high-quality cardstock to print the front of the digital card.
Include Metadata: On the back of the paper, note down key traits (e.g., personality, favorite actions) or the character's origin to help you remember how they interact in the simulation.
Organization: Use a standard trading card binder with plastic sleeves to protect your prints and keep them organized by character type or mood.
For a visual guide on how these character cards function and how to use the character customizer in-game, you can watch this tutorial:
🧠 Core pedagogy: Character cards surface values conflicts, not just right/wrong answers. The silence after a good character-based question is where learning happens.
At its core, the "Viva Project" refers to a dynamic, scenario-based learning initiative designed to bring character education to life. The Viva Project Character Cards are the physical or digital manifestation of this initiative. Each card represents a specific character archetype, personality trait, or moral dilemma.
Unlike traditional character cards that simply list adjectives (e.g., "Honest," "Brave"), the Viva Project cards are immersive. A single card might include:
The goal of the Viva Project Character Cards is to turn abstract values—like integrity, grit, or compassion—into tangible, discussable characters.
The true power of Viva Project Character Cards emerges when you compare characters. Lay two protagonists’ cards side by side. Ask:
For antagonists, create a separate deck. A great villain’s Identity Card should have a mantra that is ethically inverted but logically consistent from their perspective. Example: “Governor Cross – ‘Order requires sacrifice.’”
Character cards bring empathy, critical thinking, and perspective-taking into your classroom. Here’s how to use Viva-style character cards effectively—whether for a Socratic seminar, debate, or literature unit.
