Worked on updating the Synesthesias/PLATEAU-SDK-Toolkits-for-Unity repository to ensure graphics and visual effects compatibility with Unity 6.3. Focused on shader development and adjustments to particle-system properties, the work enabled seamless upgrades for customers by reducing visual regressions and improving rendering fidelity across the toolkit. Leveraged C# and Unity’s visual effects systems to align materials and shaders with the latest runtime requirements. The update streamlined the integration of new Unity features, allowing for faster adoption and reduced maintenance overhead. No bug fixes were recorded during this period, with all efforts concentrated on delivering this targeted compatibility feature.
