Navigation systems are fundamental components in modern game engines, facilitating the realistic and efficient movement of autonomous agents within virtual environments. This paper presents an evaluation of AlchemyNavigation, a custom navigation system developed for the Unity engine, designed to address limitations of standard solutions such as Unity’s NavMesh. This work introduces novel contributions to the field of dynamic navigation systems by proposing a triangle-based real-time modification approach that advances beyond traditional static navigation meshes, offering significant implications for procedurally generated environments and interactive virtual worlds. A series of controlled experiments were conducted to compare both systems in terms of computational performance, scalability, and flexibility. The evaluation focused on key performance indicators, including frame time, CPU utilization, and memory consumption, across multiple hardware configurations and varying agent densities. The results demonstrate that NavMesh maintains superior stability and lower computational overhead in large-scale simulations. AlchemyNavigation, in turn, offers enhanced adaptability and runtime modification capabilities, making it well suited for procedurally generated and dynamic environments. The study confirms that custom navigation systems can complement or even outperform native solutions by providing additional features tailored to specific project requirements. These findings add to current studies on AI-driven navigation frameworks in game development and immersive virtual worlds.
