**Available using the "Single" Instance mode on the Studio release of PANORA|make**; the Unified Cross-Platform feature is a suite of optimization options tailored-made for cross-platforms projects.

It is designed to allow the user to seamlessly design the Instance for both PC and Mobile/VR at the same time, without having to make 2 different materials.

To toggle it on, check the **Use Unified Cross-Platform for this Instance** checkbox in Global settings.

{% hint style="warning" %}
Unreal Engine 5.1 has bugs related to Landscape Materials on GLES 3.1.&#x20;

Unified Cross-Platform can still be used on 5.1, but problems are expected and as such isn't officialy supported.&#x20;

* **Manual Sub-Layer painting doesn't work on GLES 3.1**

It's highly recommended to use at least UE 5.2.
{% endhint %}

When checked, new tiles & options will be shown in the Interface. \
The tiles related to the Cross-Platform are indicated with the![](/files/Vh9HH0IfCskFH6qNDUys)icon.

An **Other Platforms** scalability option and Mobile Sampler meter will also appear for supported settings, allowing to **disable the feature on low-end targets**.

The Unified Cross-Platform features offers a lot of switches to disable features exclusively on Mobile to help keeping as much performance as possible, while staying under the hard 16 samplers limit.&#x20;

The next page explains all the Switches & features available for ES3.1 rendering.
