Rudimentary Shaders (1.21.7, 1.20.1) is a unique shader pack that brings a nostalgic, retro-inspired aesthetic to Minecraft. Designed to replicate the look and feel of early 3D gaming consoles most notably the PlayStation 1 – it embraces low-resolution textures, jittery camera effects, and a simplified lighting model to immerse players in a bygone era of gaming.
This shader doesn’t aim for realism it’s a stylistic throwback, intentionally gritty and blocky, celebrating the limitations that defined the visuals of the 90s.
