Worked on the st0x0ef/stellaris repository to address a rendering artifact caused by the Iris shaders mod, focusing on improving visual fidelity and compatibility with user modifications. The solution involved modifying the client-side rendering logic so that only the player model casts shadows during the shadow pass, specifically when the Iris shaders mod is active. This approach prevented space and jet suits from rendering inappropriately, eliminating the visual artifact without introducing regressions in gameplay visuals. The work demonstrated proficiency in Java, Gradle, and modding practices, resulting in improved rendering stability for modded shader configurations over the course of the month.
