# Supported Blender Features

Polygona supports a range of Blender features to enhance your 3D model customization. These features can be categorized into three main groups: object types, modifiers, and parameters.

## Object Types

Current supported object types: `Mesh`

### Mesh Objects

* Single mesh object per file

<Note>
  Support for multiple objects per file is planned for future updates.
</Note>

## Modifiers

Below are the modifier types currently supported in Polygona:

<Warning>
  Not all modifier settings may be fully supported. Complex modifier stacks might result in unexpected behavior.
</Warning>

### Edit Modifiers

* Data Transfer
* Mesh Cache
* Mesh Sequence Cache

### Generate Modifiers

### Geometry Nodes

Geometry Nodes are supported, but there are a few important points to keep in mind:

1. **Expose parameters through the Group Input node:**
   To make parameters available in Polygona, expose them through the Group Input node in your Geometry Nodes setup.

   <img src="https://mintcdn.com/polygona/3AfgVHqY5ecGYaMM/images/gn-group-input-params.png?fit=max&auto=format&n=3AfgVHqY5ecGYaMM&q=85&s=1eebc54b490020160ece84ad5671172d" alt="Geometry Nodes Group Input Parameters" width="1067" height="531" data-path="images/gn-group-input-params.png" />

   In this case, "My scale" and "level" will be available in Polygona.

2. **Set min/max values and rename parameters:**

   * Set min/max values for your parameters in the Group Input node to define their range in Polygona.
   * You can rename a parameter by double-clicking on its name if you wish to display a different name in Polygona.

3. **Add a Realize Instances node:**
   Make sure to add a Realize Instances node before your Group Output node to ensure the geometry is correctly exported.

You can download a sample Geometry Nodes file [here](https://asset-storage-polygona.lon1.cdn.digitaloceanspaces.com/samples/geometry-nodes-sample.blend) to see these concepts in action.

## Parameters

These are the parameters that are currently supported:

* Float
* Integer
* Boolean
* Enum
* Value
* Vector

Support for other parameter types will be added in the future.

## Limitations and Future Plans

* Currently, only a single mesh object per file is supported
* External assets must be packed into the .blend file
* External plugins are not supported
* File size limit of 20MB

We are continuously working to expand our supported features. Future updates may include support for multiple objects and more complex modifiers.
