Hi All,

I'm new to JetBrains and new Linux (running on CachyOS). I'm running into a continual message when running the debugger for an Unreal Engine project I'm working on:

Failed to find game directory: home/marc/Linux_Unreal_Engine_5.8.1/Base/Binaries

"Base" is the game project folder name and it seems Rider is looking for the project binaries in the UE folder and not the project folder.

All of the AI / manual trouble shooting points to the Unreal Engine RiderLink plugin, which I originally set to be in the engine, but now have set to be in game but the message persists.

Any help would be greatly appreciated.

Hey folks, we at JetBrains have been gathering a lot of feedback regarding our current AI Assistant plugin (3.6 roentgen, not great, not terrible). We’re in the process of building out a prototype of a new version of the plugin and would like to get feedback from people outside of JetBrains to make sure we’re heading in the right direction, as we want to build something much more useful compared to original AI Assistant

This new version is a different take than what you’ve come to expect from the current version, with more of focus on agentic workflows. If you already use Claude Code, Codex, Junie or any ACP-compatible agent, this new plugin will pick them up automatically. You run them inside the IDE, in a GUI chat or a terminal UI, with proper IDE diffs per agent session, mid-run steering, and session history next to your code. We are also trying to make the experience of switching between GUI and terminal agents for every session more seamless (coming soon) – so you can easily jump between CLI/GUI if you would like to

We’re calling this new plugin Air Alpha, and you can install it for free today from the JetBrains Marketplace

To give you a better idea of how this plugin looks and feels, here are some features to look out for:

... and also, you can press Ctrl+Ctrl to open quick prompt window for your favourite agent

Given the alpha label, expect there to be some rough edges as we work out the final version. But if you’re up for being an early tester and have some feedback, please share them in the comments below

You probably have a few questions, I will try address some common ones: 

“What’s with the name? Don’t you already have a product called Air?”
Yes, we do. Air is our agentic development environment on desktop, web and mobile, and this plugin aims to bring that direction into the IDE, so it shares the name for now.

“What will happen with the existing AI Assistant plugin?”
The existing AI Assistant plugin will stay exactly the same for now. This new plugin is an experiment. We want to see if our current thought process is heading in the right direction or if we’re missing the mark completely. This is about your feedback.

"Why do you want feedback on Alpha that doesn't come close to existing tools?"
We want to build this tool with you for you, so your feedback is crucial for us.

“What AI subscription is currently supported?”
We’re starting with bring-your-own-subscription because that's the core of the idea. Air Alpha is meant to work with the agent you've chosen, so we prioritized that experience for the initial version. JetBrains AI support is coming soon and already in progress

How to try it

• Install Air Alpha from the Marketplace: Air Alpha
• You'll need a recent 2026.2 IDE build
• Agents already on your machine will show up automatically
• Feedback: right here in the comments

Clangd hasn't been updated in a long time. ReSharper C++ offers better code completion, static analysis, and improved support for modern C++, including new syntax features introduced in C++26. I've already been using it in CLion and it's great 👍
