The transition of Secret Neighbor to Roblox involved significant optimization, as all game assets are streamed to players upon joining. I spearheaded the design and collaborated with engineers to develop a system that prioritizes loading assets visible from the player's initial position, subsequently loading the rest of the scene. Given the game's reliance on dynamic lighting for hiding in shadows, we implemented a custom lighting system that selectively interacts with specific surfaces. Additionally, to adapt to Roblox's basic PBR material support, I developed template materials in Substance Painter to effectively replicate the original game's material aesthetics.
