I present my largest project yet – the creation of a full-fledged game world consisting of two detailed islands connected by a complex transport infrastructure. The project has successfully completed all development steps and has been released on mobile platforms. My role and key competencies in the project: Game World Design (Level Art & Layout): I developed the "skeleton" of the entire location – from the landscape and coastline to the complex road network with interchanges and bridges. The city's architecture was designed with gameplay logic and readability in mind, taking into account the spatial clarity from a bird's eye view. Extreme Mobile Optimization: The main challenge was fitting a vast open world within the strict limitations of mobile devices. Topology: A well-defined low-poly mesh of landscapes and buildings (visible in wireframe). Draw Calls: Smart use of atlases and instancing to minimize CPU load. LOD System: Setting effective levels of detail to maintain stable FPS at long view distances. Art Direction & Mentoring: I oversaw the creation of residential and industrial areas. My team developed buildings based on my specifications, which allowed for a consistent visual style and high quality throughout the map. Integration and Technical Pipeline: Full scene setup in the engine, including material handling, light baking, and shadow optimization, which is critical to the project's commercial success. Result: The location became the foundation of a successful game. The project is not only aesthetically pleasing but also commercially viable, demonstrating an ideal balance between visual quality and technical performance.
