GoE PSX Overdrive Toolkit is a Blender add-on for converting scenes into retro PS1 / PSX-style renders. It gathers style presets, low-poly degradation, GeoNodes vertex wobble, texture dithering, PSX sky HDRs, atmosphere presets, and retro render settings into a single N-Panel workflow. The add-on works with EEVEE and Cycles, and applies to characters, props, environments, and general mesh objects.
Ten style presets — including PS1 Horror, Silent Hill Fog, Resident Evil, Retro Anime, Low Poly Arcade, Dungeon Crawler, Dark Fantasy, VHS Dirty, CRT Monitor, and Dreamcast Clean — each set geometry reduction, vertex wobble, flat shading, triangulation, and overall PSX intensity. An authenticity slider scales the effect from subtle stylization to heavy degradation, while 12 atmosphere presets and 10 PSX sky HDRs handle mood and environment. Texture dithering offers three methods for color reduction and pixel banding, and Render FX covers low-resolution presets, a 5-bit color depth effect, shadow options, and denoising toggles.
A safe workflow keeps the original scene intact through duplicate-before-applying, apply-to-selected or whole-scene options, a before/after toggle, material backup, and tools to restore materials or remove effects. The download includes the add-on ZIP, presets, sky HDRs, and a PDF Quick Start Guide, and is distributed under the GPL license.
