# Prepare Your Blender Files

> Guidelines for preparing Blender files for upload

## File Requirements

### Supported Blender Versions

We officially support **Blender 4.x** files. Files created in earlier versions may work, but compatibility is not guaranteed.

### Single Mesh Object

Currently, your Blender file should contain **only a single Mesh object**. Support for multiple objects will be added in the future.

### Pack External Assets

Any imported external assets, such as textures or fonts, **should be packed** into the Blender file.

### File Size Limit

The total file size **must not exceed 20MB**.

### External Plugins

**External plugins are not supported** at this time. This feature may be added in future updates.

## Preparing Your File

1. Ensure your scene contains **only one Mesh object**.
2. Go to **File > External Data > Pack All Into .blend** to include all external assets.
3. Check that your file size is **under 20MB**.
4. **Remove or disable any external plugins** used in your project.

By following these guidelines, you'll ensure that your Blender file is compatible with our current upload system.
