How to Create Assets for Decentraland
Decentraland is a unique and exciting digital realm that stands out as one of the first fully decentralized virtual reality platforms. Built on the Ethereum blockchain, it’s a world where users, referred to as ‘landowners,’ can buy, sell, and build upon digital parcels of land, creating a vivid tapestry of experiences and opportunities. For that reason, some people would like to know how to create assets for Decentraland.
The virtual space in Decentraland is not merely a static digital landscape but a dynamic universe filled with games, applications, and other interactive experiences. Assets in Decentraland, which can range from pieces of land to buildings, wearables, and more, hold significant importance as they shape the very nature of this digital world.
These assets, owned and controlled by users, serve as building blocks for the ever-evolving landscape of Decentraland. They are not only manifestations of the creative potential of the users but also provide tangible value in the form of virtual real estate and other digital goods. Consequently, these assets can be traded, used, or transformed, adding layers of interaction, commerce, and creativity, thereby enriching the overall user experience in Decentraland.
Basics of Creating an Asset in Decentraland
1. Understanding what qualifies as an asset in Decentraland
In Decentraland, an asset refers to any digital commodity or property a user owns within the platform. This could include LAND (parcels of virtual real estate where users can build upon), MANA (Decentraland’s native cryptocurrency used for transactions), wearables (virtual clothes and accessories for avatars), and unique 3D models of buildings, structures, or artwork.
These Decentraland assets managed via blockchain technology, represent elements of value that users can trade, sell, buy, or simply use to enhance their experience within Decentraland. The inherent nature of these assets being decentralized means they are directly controlled by the user, giving them autonomy and a wide range of possibilities in this virtual world.
2. Identifying the types of assets you can create (land, wearables, buildings, etc.)
In Decentraland, users have the freedom to create a variety of assets, each of which adds to the richness of the virtual world’s experience. One of the most significant assets is LAND, parcels of virtual land on which users can construct various structures. Users can create Buildings, essentially 3D models placed on these LAND parcels, to create anything from homes to shops to art installations.
Another category of assets is Wearables, which include clothing, accessories, and other avatar enhancements that users can design to personalize their Decentraland personas. Additionally, users can create unique pieces of Art or collectibles, which can be minted as Non-Fungible Tokens (NFTs) and traded within the community. The potential for creativity is immense, allowing users to bring their virtual imaginations to life.
Essential Tools and Asset Creation Platforms
1. Introduction to Decentraland’s Builder tool
When learning how to create assets for Decentraland, it is important to understand the tools needed. Decentraland’s Builder tool is a user-friendly, web-based platform designed to enable users to create and customize their LAND parcels without coding skills.

Blockchain technology, particularly the Ethereum blockchain, ensures that all asset ownership details and transactions are transparent, secure, and immutable.
Each asset in Decentraland is represented as a Non-Fungible Token (NFT) on the Ethereum blockchain, which certifies its uniqueness and ownership details. Smart contracts, which are self-executing contracts with the terms of the agreement directly written into code, manage the creation, sale, and trading of these assets.
They enable transactions directly between users without intermediaries, ensuring security and trust. This combination of blockchain technology and smart contracts underpins the decentralized nature of Decentraland, giving users full control over their virtual assets.
Step-by-step Guide to Creating Assets in Decentraland
1. Planning your asset
It’s crucial to plan effectively before embarking on creating an asset in Decentraland. This starts with determining the purpose of the asset. The purpose could be varied – it might be a building that provides a virtual gathering place, an artwork that enhances the aesthetics of your LAND, a piece of clothing that adds uniqueness to your avatar, or a game that provides entertainment to visitors.
Defining this purpose guides the design process and ensures the asset adds value to the user experience. Following this, sketching or outlining the asset on paper or using digital design tools is recommended. This preliminary visualization helps identify the asset’s basic structure, size, and features.
It serves as a blueprint that simplifies the creation process, allowing you to anticipate potential issues and make necessary adjustments before moving into 3D modeling. This two-step approach helps ensure that the final asset aligns with your initial vision and fulfills its intended role within the Decentraland ecosystem.
2. Creating your asset
After planning your asset, the next phase involves creating the asset using 3D modeling software. Tools such as Blender, SketchUp, Maya, or 3ds Max can be used for this purpose.
It is important to know, when learning how to create assets for Decentraland, that building the 3D model requires a mix of artistic and technical skills, as you’ll need to shape your asset, add texture, color, and potentially animations, all while ensuring that it complies with Decentraland’s technical specifications, such as polygon count limits. Once the 3D model is satisfactorily designed and perfected, the next step is to export the model in a Decentraland-compatible format.
Decentraland currently accepts 3D models in the .glTF format, a widely adopted open standard for 3D assets. The .glTF format supports various features, including textures, animations, and skin, making it versatile enough for most asset types. Remember to keep the file size manageable to ensure optimal performance within the Decentraland environment.
3. Importing and modifying your asset in Decentraland’s Builder
Once your 3D model is ready and exported in the .glTF format, the next step involves importing it into Decentraland’s Builder. This web-based tool allows you to drag and drop your asset onto your LAND parcel, making the integration of your custom asset into the Decentraland world a seamless process.
After importing, you can manipulate your asset in various ways, such as by positioning it at a particular location on your LAND, rotating it to get the desired orientation, and scaling it to adjust its size according to your needs. It’s crucial to review the placement and scale of your asset from multiple angles to ensure it aligns with the overall design of your LAND parcel.
If desired, you can add interactive elements to your asset using Decentraland’s SDK. This could include clickable links, triggers for animations, or even complex gameplay mechanics if you’re building an interactive game. Such interactive elements can enhance the user experience, making your asset more engaging and dynamic within the Decentraland environment.
4. Testing your asset
After fully integrating your asset into Decentraland, the final stage involves testing its functionality and appearance. This is a critical process to ensure your asset looks and behaves as intended within the virtual environment. Explore your asset from different angles and lighting conditions, ensuring the textures, colors, and details appear correctly.
This is crucial when learning how to create assets for Decentraland since if your asset has interactive elements, test these thoroughly to ensure they function as expected. For instance, if it’s a clickable object, does the click trigger the right response? If it’s a wearable, does it fit the avatar correctly? These and many more considerations come into play during testing.
Once you identify issues, make the necessary fixes, and continue optimizing the asset for performance. This could involve reducing the polygon count, optimizing textures, or streamlining the code for interactive elements. Through testing and optimization, you ensure that your asset adds aesthetic value and contributes positively to the overall user experience in Decentraland.
Blockchain Integration and Smart Contracts
1. Overview of Ethereum blockchain in relation to Decentraland assets
The Ethereum blockchain is central to how assets function within Decentraland. Ethereum, known for its smart contract functionality, is the underlying technology allowing users to prove ownership and trade assets transparently and securely. Each asset in Decentraland – be it LAND, MANA, or other digital items – is represented as a Non-Fungible Token (NFT) on the Ethereum blockchain.
An NFT is a unique token that can’t be replaced with something else, meaning each asset in Decentraland is one-of-a-kind. When a user buys an asset, the transaction is recorded on the Ethereum blockchain, and ownership of the NFT is transferred to the buyer’s Ethereum address.
This system ensures that all transactions are transparent and immutable and that the provenance of each asset can be traced back through its transaction history. Consequently, the Ethereum blockchain provides the decentralized infrastructure that makes the user-owned and controlled virtual world of Decentraland possible.
2. Explanation of the role of smart contracts in verifying and managing assets
Smart contracts play a crucial role in managing and verifying assets in Decentraland. A smart contract is a self-executing contract with the terms of the agreement directly written into lines of code. In the context of Decentraland, smart contracts facilitate asset creation, ownership, and trading.
For instance, when an asset like LAND or wearable is created, a smart contract minting the corresponding Non-Fungible Token (NFT) is executed, effectively verifying the asset’s existence and assigning ownership. Additionally, when assets are bought, sold, or traded, smart contracts transfer ownership between parties, ensuring that each transaction is secure, transparent, and irreversible.
The smart contracts automatically enforce the agreed-upon terms, reducing the risk of fraud and eliminating the need for a trusted third party. This automation provided by smart contracts forms a key part of Decentraland’s decentralized infrastructure.
3. Procedure for minting and deploying NFTs (Non-Fungible Tokens)
Minting and deploying Non-Fungible Tokens (NFTs) is integral to creating and establishing ownership of assets in Decentraland. Minting is creating a new token, in this case, an NFT, on the blockchain. Once you’ve created your digital asset for Decentraland, be it a piece of LAND, a building, a wearable, or an artwork, you must mint an NFT to represent this asset on the Ethereum blockchain.
This process is executed through a smart contract, which creates a new NFT linked to your asset and assigns it to your Ethereum address, effectively establishing your ownership of the asset. The details of the NFT, including its ownership, unique characteristics, and metadata linking it to your digital asset, are then recorded on the blockchain.
Once minted, the NFT can be deployed, listed on various marketplaces for trading, or used within the Decentraland environment. The entire procedure is conducted in a decentralized manner, ensuring transparency and security of ownership.
4. Guide to linking your asset with its corresponding NFT
Linking your asset with its corresponding Non-Fungible Token (NFT) is a crucial step in learning how to create assets for Decentraland. This process essentially assigns a digital identity to your asset on the blockchain. When you mint an NFT for your asset through a smart contract, the NFT is created with specific metadata that links it to your asset. This metadata can include information such as the name, description, image, and specific attributes of the asset.
In addition, the metadata will often include a pointer to a secure, decentralized file storage system, such as IPFS, where the actual data of the asset (like a .glTF file for 3D models) is stored.
This way, the NFT serves as a unique, immutable, and transparent record of your asset on the blockchain, allowing anyone to verify the ownership and authenticity of the asset. With the asset and its corresponding NFT linked, you now have a blockchain-verified digital asset you can use, sell, or trade in the Decentraland ecosystem.
