I will create a game or gameplay system that you have in mind and make the process as iterative as possible so you always get what you asked for.ย  I have experience with clients hiring me after other freelancers failed to deliver what they needed or believed it was not possible to implement, and I solved the problem. What tasks can I accomplish: - Building a Finite State Machine for AI or various characters in a game - Implementing Multiplayer - Implementing gameplay mechanics - Implementing procedural shaders with Shader Graph - Integrating various assets into a game - Refactoring code - Prototyping a game - Developing various placeholder or simple assets for a game I have worked as a game dev and 3D modeler for 5+ years as of now. I helped clients to bring various tasks they needed, including building an addon that uses an isometric system to stack objects on each other without z-index issues. Using my knowledge of procedural materials, I created a procedural island for a calendar application, made a rocket launcher simulator for presentation for military organizations, developed card-based combat for a visual novel game, and so on.ย ย  My unique value is in having both game development and programming skills and also experience with making 3D models. I have good orientation in 3D space and have skills in building procedural materials using a Shader Graph and also using procedural textures for various other purposes, for example, generating specific 3D terrains or objects.ย  If you're ready to bring your game idea to life, message me to discuss your project timeline and scope.
