ATS ReShade + Weather Mods 2.1 Install Guide

What this covers

• Installing ReShade correctly for American Truck Simulator before touching any mod files
• The Project Ultimate RealEye and Weather 2.0 mods specifically, not a generic ReShade preset
• Load order — the most common reason this setup doesn't look right on a first attempt
• Troubleshooting the visual glitches and crashes that usually come from a missed step

Why load order is the part people get stuck on

ReShade itself is a fairly quick install, but ATS graphics overhauls live and die on load order — install the RealEye and Weather 2.0 mods in the wrong sequence, or on top of an existing ReShade config, and you'll get anything from washed-out colours to outright crashes on launch. This guide is built around that failure point specifically, since it's where almost everyone gets stuck.

What Project Ultimate's mods actually change

RealEye and Weather 2.0 are a combined lighting, colour-grading and weather overhaul for American Truck Simulator — the kind of change that's genuinely dramatic in motion but easy to get only half-installed if a step gets skipped. The full 34-minute video is worth the runtime if you want it done right the first time rather than debugging it afterwards.
