<p>Photon Engine provides different multiplayer SDKs to enable the development of multi-player (for gaming contexts) or multi-user (for non-gaming contexts) applications. These SDKs empower developers to create multi-player or multi-user games and applications, either as standalone projects or integrated into development platforms like Unity and Unreal. <ahref="https://www.photonengine.com/fusion">Fusion SDK</a> is a Unity Verified Solutions that offers powerful features needed to build multi-player applications.</p>
<h2>Photon Fusion Addons for Logitech MX Ink</h2>
<p>In addition to the Fusion SDK, Photon offers a collection of addons to accelerate XR prototyping. A specific Logitech MX Ink Integration addon is available, allowing you to use the Logitech MX Ink in a multi-player setting. This addon includes a simple demo scene to illustrate its functionality. More details in <ahref="https://doc.photonengine.com/fusion/current/industries-samples/industries-addons/fusion-industries-addons-mxinkintegration">this page</a>.</p>
<p>To try out this demo scene, download the <ahref="https://doc.photonengine.com/arvr/current/meta-quest/fusion-meta-xr-integration">Meta XR Integration Unity project</a>. The scene is located in the <code>Assets\Photon\FusionAddons\MXInkIntegration\Demo</code> folder. You will need to create a Photon account and generate an AppID, which must be set in the Unity Fusion settings (found in the <code>Tool/Fusion/RealTimeSettings</code> menu) as explained <ahref="https://youtu.be/HwMgchSY43M?t=197">in this video</a>.</p>
<h2>Additional Samples</h2>
<p>For a deeper understanding of how to use the Photon Fusion multiplayer SDK for XR, along with the Logitech MX Ink demo scene, you may find this <ahref="https://doc.photonengine.com/fusion/current/technical-samples/fusion-vr-shared">technical sample</a> and <ahref="https://www.youtube.com/watch?v=DdQi7DqHjdQ">video</a> helpful.</p>
