Kazuaki Terabayashi focused on stabilizing tile attribute handling in the Synesthesias/PLATEAU-SDK-for-Unity repository by implementing a targeted fix for attribute data integrity. Using C# and leveraging skills in Unity development and asset management, Kazuaki addressed a bug where tile attribute information could be lost during the build process. The solution involved preventing the stripping of unused mesh components, thereby preserving essential attribute data, and refining the method for identifying target object names for dynamic tiles. This work improved build reliability and reduced the need for post-build debugging, demonstrating a thoughtful approach to maintaining data integrity within complex Unity editor workflows.
