During November 2025, Tae Kim developed new crafting recipes for Red sand and Red Sandstone in the GTNewHorizons/NewHorizonsCoreMod repository, focusing on expanding the material processing workflow for players. Using Java and leveraging modding techniques in game development, Tae introduced multiple processing methods that allow players to produce these materials through various in-game systems. The implementation aligned with the project’s existing recipe framework, ensuring consistency and maintainability. While no major bugs were addressed during this period, the work contributed depth to early-to-mid game progression and supported a more diverse material economy, reflecting a focused and well-integrated engineering effort.
