During April 2025, Snoopy focused on improving rendering stability in the st0x0ef/stellaris repository by addressing a visual artifact caused by the Iris shaders mod. Snoopy identified that the artifact stemmed from space and jet suits casting unintended shadows during the shadow pass. By applying a targeted Iris compatibility patch, Snoopy ensured that only the player model casts shadows when the mod is active, restoring visual fidelity and maintaining compatibility with user mods. This work involved client-side development and modding using Java and Gradle, and demonstrated careful attention to compatibility and regression-free integration, though no new features were introduced this month.
