# Rendering

The Metadata Renderer is a vital component within the Degen Engine protocol, responsible for generating metadata and media assets for NFTs. As a hybrid renderer, it combines traits to produce a single image or media asset displayed across NFT marketplaces, wallets, and other platforms.

### How the Metadata Renderer Works

When an NFT is created, it is assigned a collection of traits stored within the contract. These traits contain essential information, such as the NFT's name, image, and other metadata. As new traits are added or burned, the renderer automatically updates the NFT's media asset to ensure accurate representation.

Rendering an NFT's media asset involves merging the individual media assets of each trait into one unified asset. For instance, if an NFT possesses traits for the head, torso, and legs, the metadata renderer will combine the respective media assets to generate a complete image of the NFT.

### Benefits of the Metadata Renderer

By merging traits in this manner, the Metadata Renderer facilitates greater flexibility and customization in NFT design. Creators can effortlessly add or remove traits to modify an NFT's appearance or functionality without needing to create an entirely new asset.

Moreover, the Metadata Renderer guarantees consistent NFT representation across all platforms. When users view an NFT on a marketplace or wallet, they see the same media asset generated by the renderer. This consistency creates a unified and standardized user experience for NFTs, which is crucial for widespread adoption of this technology.

Users can also create their own Metadata Renderer to render more complex media assets. In this case, they can establish their own rules for calculating and applying Render Order.
