# Unreal Engine SDK

{% hint style="warning" %}
This documentation refers to the [**Unreal Engine SDK**](https://ndi.video/for-developers/ndi-unreal-engine-sdk/), a separate SDK that adds full IP video and audio support within Unreal Engine 5.3, unlocking real-time 3D, AR, and VR content creation. If you want to learn more about the complete NDI SDK, check the online [documentation](/all/developing-with-ndi/sdk.md) and download it [here](https://ndi.video/for-developers/ndi-sdk/).
{% endhint %}

This documentation is paramount for developers and integrators seeking to combine the potential of NDI technology with the creative possibilities of [Unreal Engine](https://www.unrealengine.com/pt-BR), a powerful 3D creation software.

This documentation is continuously updated to match the most recent version of our Unreal SDK. The current version of the Unreal Engine SDK is **version 3.7**. You can check the most meaningful updates in our [release notes.](/all/developing-with-ndi/utilities/unreal-engine-sdk/release-notes.md)

For information on Unreal Engine, visit their [**FAQ** ](https://www.unrealengine.com/en-US/faq)or [**Documentation** ](https://dev.epicgames.com/documentation/en-us/unreal-engine/unreal-engine-5-5-documentation)page.

{% hint style="info" %}
Read our [**White Paper**](/all/getting-started/white-paper.md) if you'd like to know more about the vision of NDI and our technology's fundamental features, protocols, and settings.

> Wondering about Unreal Engine on Mac? Unfortunately right now Unreal is only available for Windows. See our [FAQ ](/all/faq/sdk/can-i-use-the-unreal-sdk-on-mac.md)on it.
