## World Editor
The viewport of the world editor presents the virtual scene of the metaverse world. This editor allows you to edit the details and aesthetics of the world, including terrain height ratio, planting trees, virtual buildings, etc. Only creators with the Genesis NFT can use the world editor.
## Getting Started
This section explains how to use the world editor to edit your metaverse project and provides basic information to help you get started. The following sections describe more about how to use the world editor to handle 3D models.
### Setting Up the World
Adjust the height and resolution of the world to edit your world:
* **World Height** is the ratio of the world's height, and you can drag it left or right to set the height ratio of the world.
* **Preview Resolution** is the resolution of the world. According to the specifications of your computer hardware, you can drag it left or right to set a high or low resolution. The higher the resolution, the higher the resolution of the 3D models, terrain, and sky displayed in the virtual viewport.
{% hint style="info" %}
The resolution setting does not directly affect the resolution of the 3D building in the 3D experience layer (low/high polygon). For more information about low/high polygon 3D model buildings, please refer to [here](https://allimeta.gitbook.io/creators-manual/manage-your-world/edit-your-metaverse-world/world-limits).

* 「Flat」enables parallel terrain mode
* 「Height」enables elevation terrain mode
### Light Setting
Click on 'Environment Setting' in the editor's hierarchy, and then click on 'RuntimeLightSetting Component' to open up the lighting settings.
* **Direction:** Direction of light rays
* **Angle:** Angle of light rays
* **Strength:** Intensity of light rays

## 3D Model Management Tool
Through the use of a public model management tool, it is easy to manage 3D objects that are allowed to be edited within the universe. The model management tool is divided into public and private categories:
* Public Model Management Tool - allows for the addition or removal of 3D models that are open for external use. All uploaded 3D objects will be added to the land editor of everyone.
* Private Model Management Tool - allows for the addition or removal of 3D models created by the creator. 3D objects uploaded through this tool will only be added to the creator's editor.
### Supported Formats
The 3D models added in the model editor are in a **.ZIP format**, which must contain the 3D model format developed by the Unity application and a texture image file.

2. Fill in the necessary information for the 3D model on the page:
* Enter the **name** of the 3D model.
* Dropdown menu to select the label of 3D model (such as: house, plant, lamp...) used for categorizing the 3D model you added.
* Display when 3D model is closer (requires < 5000 polygons)
* Display when 3D model is further away (requires < 200 polygons)
* Convenient for identifying and viewing the appearance of the 3D model
3. Finally, please click on to complete the upload and add it to your editor.

### Using the Avatar scale
When starting to edit, it is recommended to use the built-in Avatar tool provided by AlliMeta as the scale for designing 3D buildings. The Avatar tool within the editor and the Avatar scale in the 3D experience layer have a 1:1 ratio.
### Colors and Lighting
The world editor simulates the colors and lighting of the 3D experience layer. The lighting and color presentation of actual 3D models, landscapes, terrains, water, and other scenes will mainly follow the 3D experience layer.
### Editing your metaverse
