Assetto Corsa EVO Mods: What Works in 2026 (SDK, Prism & the New Rules)

If you’ve followed our guides on Custom Shaders Patch, Pure and Content Manager, you already know how completely those tools transformed the original Assetto Corsa. So when Assetto Corsa EVO landed, the natural first question was which of them to install first. Here’s the answer, and it’s worth knowing before you go hunting: none of them work on EVO, and they’re not going to. But that isn’t the end of the modding story – it’s the start of a new one, and it’s moving faster than you’d think.

Why Content Manager, CSP and Pure don’t work on EVO

The short version is that EVO is a different engine. The original Assetto Corsa ran on the 2014 Kunos engine, and the entire modding stack – Content Manager, CSP, Pure, Sol – was built to hook into that specific renderer. EVO is not a fork of that codebase, and it isn’t Unreal Engine either (that’s what powers Assetto Corsa Competizione). It’s an all-new engine that Kunos built from scratch, and Kunos co-founder Marco Massarutto said as much back when the project was still called Assetto Corsa 2: “We are developing new technology for the engine. We will not use Unreal because we need greater flexibility.”

That single decision is why your existing tools are so much dead weight here. Content Manager, CSP and Pure don’t just need a compatibility update – they’d need a full rewrite against a renderer that works nothing like the old one. So the muscle memory of “install Content Manager, then CSP, then Pure” doesn’t transfer. EVO has no launcher app at all. You work with the game’s own native interface, and mods go into a folder. If you’ve spent years inside Content Manager, that takes some adjusting to.

How Kunos changed its mind about modding

The most interesting part of the EVO modding story is that it nearly went a very different way. When Kunos first talked about modding in October 2024, the plan was cautious: mods would arrive only after the full 1.0 release, and they’d pass through an official vetting process, partly so Kunos could work with car manufacturers on licensing. For a community raised on the anything-goes freedom of AC1, that landed with a thud.

Then the plan kept softening, and every change was in the modder’s favour. By April 2025, Kunos had decided to bring the tools forward into Early Access rather than hold them until 1.0, so the community could help shape them. And in February 2026, Massarutto went further than anyone expected, dropping the vetting gate entirely: “we are going to provide all the community with the modding tools with no limitations.” That’s a real reversal from the original position, and it’s the throughline worth holding onto – EVO’s modding future is open, not gated.

What the official SDK does, and what it doesn’t yet

The tools arrived in phases. Update 0.7, on 3 June 2026, shipped the first version of the ACE SDK, distributed through the Tools section on Steam the same way iRacing and other titles hand out their editors. This first release is a car editor, and at launch it was single-player only – you could build and drive a car mod on your own machine, but not take it online.

Update 0.8, in early July 2026, changed that by adding multiplayer mod support, so community cars can now be used on servers that choose to allow them. It’s the difference between a toy and a tool: modded content that only works in single-player is a curiosity, but modded content you can race online is the thing that built AC1’s legendary scene in the first place. One wrinkle to know if you plan to run mods on a server: a later point release (0.8.1) added a server-side check, so mods built before it need to be re-exported through the SDK to generate a JSON file before a server will accept them as valid. If a mod that worked last month suddenly won’t load online, that’s usually why.

What the SDK cannot do yet is tracks. The first release is cars only. Kunos has confirmed that track tools are coming – Massarutto has even floated a LiDAR-based terrain editor – but as of now, no track modding exists. That’s the single biggest gap between EVO’s toolkit and the mature AC1 one, and it’s worth being clear-eyed about it.

The mods that exist right now

Here’s where a lot of the online chatter gets it wrong in both directions. It’s not true that “no mods exist” for EVO, and it’s not true that it already has an AC1-sized library. The reality sits in between, and it’s exactly where you’d expect a two-month-old SDK to be. Real, named car mods are out there and driveable. A few of the ones doing the rounds:

• An Abarth 1000 TCR by Pessio, a known AC1 modder, described by its own creator as a beta built mostly to learn the new SDK
• A Porsche 992 GT3 RS Manthey Racing pack by Ceky Performance
• A BMW M3 Touring 24h
• Formula 1 cars and the 499P Le Mans Hypercar by SimDream
• And, predictably, a driveable banana car – the sort of chaotic joke content that shows up in the opening weeks of any modding scene

Installing them is not the Content Manager experience you’re used to. There’s no launcher, no drag-and-drop app. You copy the mod folder into your Saved Games\ACE\mods directory, mind the classic folder-inside-a-folder trap that catches everyone once, and the game picks it up natively. Most of the current mods are hosted on ModLand, which has a dedicated EVO section. The best mental model I can give you is this: what exists today is roughly where the original Assetto Corsa was in its first few months. Functional, real, and early.

Prism: the EVO answer to Custom Shaders Patch

This is the part that will interest anyone who fell in love with what CSP and Pure did to AC1’s visuals. There is now an EVO-native equivalent, and it’s called Prism, made by Real Sim Roads. It describes itself as the first custom shaders patch and content manager for Assetto Corsa EVO, and on paper it’s doing the same job CSP did on the old engine – only rebuilt from the ground up for EVO’s DX12 renderer.

The technical approach is clever. Rather than touching game files, Prism uses a proxy DLL that swaps compiled shader code at runtime, so nothing on disk is modified – it’s all done in memory while the game runs. Its own documentation lists targeted replacement of dozens of the game’s shaders on a per-material basis, tone-mapping and LUT control (GT tonemap, AgX, ACES, your own custom LUT), and true HDR output. It also bundles a lightweight content-manager-style app for managing shader configs and per-car profiles, which will feel familiar if you’re coming from the old workflow.

Two caveats before you get excited. First, Prism is a paid product – it launched via Patreon at around $4 a month at the early rate – not a free community mod the way CSP has always been. That’s a real shift in the culture of AC modding, and how the community takes to it remains to be seen. Second, the performance and quality claims above come from Prism’s own site; it’s early, there’s no long track record yet, and I haven’t seen enough independent testing to tell you how it holds up over time. Treat it as promising rather than proven, and go in knowing it’s a subscription, not a gift.

What’s still missing

It’s worth laying out the gaps plainly, because a young modding platform is defined as much by what it can’t do yet as by what it can. Track mods are the big one – the SDK is cars-only, so the entire world of community circuits that AC1 is famous for simply doesn’t exist on EVO yet. Beyond Prism, there’s no broad third-party graphics ecosystem, and nothing like the deep bench of apps, plugins and timing tools that grew up around AC1 over a decade. The community hubs are still forming too. OverTake and ModLand are hosting content, and the official Kunos forum carries the SDK documentation, but the sprawling ecosystem AC1 modders take for granted is a way off.

None of that is a criticism, really – it’s the ordinary shape of a scene a couple of months into its life. It just means you should set your expectations to “early adopter”, not “drop-in replacement for my AC1 setup”.

How to get started

If you want to get hands-on rather than just watch, the path is short. Grab the ACE SDK from the Tools section of your Steam library – it sits alongside the game itself. For installing car mods, download them (ModLand is the main hub for now), and copy the mod folder into Saved Games\ACE\mods. Watch the folder-inside-a-folder trap: if a mod won’t appear, you’ve probably nested it one level too deep. If you’re planning to race mods online, remember the 0.8.1 rule – anything built before that point release needs re-exporting through the SDK first, or servers will reject it.

For the authoritative SDK documentation, the official Kunos forum is the right place to look rather than any third-party chat server. And if the fundamentals of how shaders, weather and content management work are still a bit fuzzy, our older guides on Custom Shaders Patch and Sol versus Pure still explain the concepts well, even if the specific tools have changed. While you’re setting EVO up, our AC EVO wheel settings guide will get the force feedback right on your Fanatec, Moza or Simucube.

The bottom line: EVO modding in 2026 is early, but it’s real, and Kunos has committed to keeping it open. The tools you knew from AC1 don’t carry over, but the spirit is starting to. Give it a year and this could look very different. I’ll be watching it closely, and I’ll keep this guide updated as the scene grows. See you out on track.

Assetto Corsa EVO modding: common questions

Does Content Manager work with Assetto Corsa EVO?

No. Content Manager was built for the original Assetto Corsa’s 2014 engine, and EVO runs on an all-new Kunos engine. EVO uses its own native interface instead, and mods are installed by copying folders into the game’s mods directory.

Can I use CSP and Pure on Assetto Corsa EVO?

No. Custom Shaders Patch and Pure are AC1-only tools and don’t work on EVO’s new engine. The closest EVO-native equivalent is Prism by Real Sim Roads, a paid third-party shaders-and-content-manager tool, though it is early and not officially sanctioned by Kunos.

Are there mods for Assetto Corsa EVO yet?

Yes, but the scene is young. The official car-modding SDK arrived in update 0.7 (June 2026) and multiplayer mod support followed in 0.8 (July 2026). Real, named car mods exist and are hosted on sites like ModLand. Track mods do not exist yet – the SDK is cars-only for now.
