AI also assisted in creating code documentation and example implementations.Human Contributions: I personally designed the tool's architecture, defined all feature requirements and workflows, and specified the editor integration approach. I conducted extensive testing across different terrain configurations, debugged edge cases, optimized performance for large-scale placements, and validated Unity 6 API compatibility. I also curated and organized the example content, designed the user workflow for the editor interface, and made iterative refinements based on hands-on testing to ensure professional-quality results.
