Total MQTT: Advanced MQTT Integration for Unreal Engine

Total MQTT seamlessly integrates MQTT protocol support into Unreal Engine, accessible through both Blueprints and C++. This plugin enables real-time communication in games and interactive applications, featuring secure message handling, multiple Quality of Service (QoS) levels, and enhanced security with TLS encryption, including support for Mutual TLS and SNI, encrypts certificates for packaging and supports dynamic certificate generation from external API's.

Designed for developers aiming to incorporate complex IoT or real-time communications into their projects, Total MQTT offers easy setup, robust MQTT client/broker management, and flexible message subscription and publishing capabilities within the Unreal environment. Whether you're creating multiplayer games, virtual reality experiences, or advanced simulations, Total MQTT ensures efficient and secure interactions with MQTT brokers.

The plugin supports both asynchronous and synchronous clients and offers configurable options such as message queue processing, allowing customization to fit specific project requirements. Total MQTT supports multi client and multi broker simultaneously , providing versatile connectivity solutions for developers.

Includes a blueprint helper library for serializing/deserializing actors and publishing.
