This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.
1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."
Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.
Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.
2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.
3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.
4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.
MateEngine is a lightweight desktop companion app with full custom VRM model support. Bring 3D anime-style characters to life on your screen with idle animations, drag and dance features, and low resource usage and open-source.
MateEngine is a lightweight, customizable desktop companion app that brings 3D anime-style characters to life on your screen. Built with VRM model support, it allows you to inject your own avatars and watch them interact, idle, and even dance—right from your desktop.
This project is a alternative aimed at giving users more control and flexibility without relying on expensive model packs or locked-down systems. Whether you want a simple virtual presence or a more animated character hanging out while you work, MateEngine is designed to be approachable and performance-friendly.
Important: This app includes the default model "Zome." Hatsune Miku is not included.
To use custom models, you must download them from websites that offer .vrm files, or commission artists who create or convert models to the VRM format.
I am not responsible for the quality of third-party models. If you experience clipping or similar issues, the model's author is responsible, not this app.
Drag your pet onto a window and it will relax on top! Perfect for watching videos she'll watch with you. Or let her quietly spy while you do your homework, hehe.
This feature is experimental and not fully developed. Please avoid using it with apps that have anti-cheat protection enabled.
She will start dancing when you play music! You can decide which apps are allowed to trigger dancing.
Open the Options menu, go to the audio sources, and whitelist your music apps.
Tip: Start the music app first (e.g. Spotify), then open the menu and add it to the source list!
Not just the head — her eyes, head, and spine all follow your mouse cursor!
This makes the movement look smooth and natural compared to other desktop pets.
Careful! Sometimes she’ll try to grab your mouse — hehe!
Move your cursor near her hands or arms and watch her try to catch it!
Hover your mouse over sensitive areas like the head or belly to trigger cute gestures!
For example, hovering over her head makes her giggle and spawn sparkle effects, making her feel comfy.
You can chat with your pet anytime! Just note that it’s a small, local AI with simple messages.
For more complex conversations, you can use mods with your own models and messages!
When you drag her to the taskbar, she’ll lay down and relax on a big candy macaron,
watching your mouse cursor with sleepy eyes.
You can reposition her by clicking and dragging her with your mouse.
Just hold the button down and move her wherever you like!
Hold your mouse over her feet for a few seconds and she’ll transform into a tiny,
adorable chibi version of herself — extra smol and cute!
You can change her size, animation speed, language, and modes.
There are also graphics and FPS settings for low-end (potato) PCs!
You can turn off lighting — perfect for VRM models with emissive textures!
Pair it with the glow/bloom toggle and your pet will shine like a diamond in the dark
Modding is supported! Load your own VRM model by pressing the VRM button.
If your model doesn’t load, it’s likely corrupted or not exported correctly.
Make sure to export using the correct format:
VRM0.X: Uses MToon Shader
VRM1.X: Uses MToon10 Shader
Also make sure your model uses a proper humanoid bone setup.
MateEngine follows the official VRM loading specification, so model issues are not caused by the app.
It’s easy! Just start MateEngine and you’ll be greeted by Zome.
Right-click Zome to open the Options menu — here you can change graphics, effects, audio, and choose which apps make the pet dance.
Tip: Start the sound app (e.g. Spotify) and play something before opening the menu, or it won’t appear in the sound source list. Then add it to the Danceability list and save.
Idle Animations: 10 different idle animations for when the pet is relaxing on your desktop!
Drag Animation: 1 drag animation plays when you move your pet around the desktop.
Dance Animation: The pet dances when music plays on apps like Spotify, Chrome, and others!
Head Tracking: The pet follows your mouse with its head.
Eye Tracking: The pet's eyes also follow your mouse for extra detail!
Hand Tracking: When you hover your mouse near its hands, the pet will try to catch and hold it!
Head Pats: Hovering over the pet’s head makes it shake, jiggle, and spawn adorable heart particles.
Spine / Chest Tracking: Head, eye, and hand tracking aren’t enough! When you move the mouse, the pet will also move its upper body in that direction to make movement more realistic!
Chibi Mode: Hover over its feet for 3 seconds to transform the pet into a chibi version! Works with custom VRM models.
Sensitive Parts: The pet will react shyly and cover certain areas if you hover over them.
Custom VRM Support: Load any VRM using MToon shaders (UniVRM VRM0). VRM1.X (MToon10) support coming soon!
Particle Effects: Includes various particle effects, with more to come!
Auto-Load Custom VRM: Your custom model loads automatically on startup.
MateEngine is designed to be lightweight on CPU and GPU resources. RAM usage depends on your model’s complexity, especially texture sizes. For example, a high-res VRM model may use around 200MB of RAM. Simpler models use significantly less.
Animation transitions are smooth and fluid, providing a more natural experience compared to other apps in this space.
Menu color customization
Wallpaper Engine integration
Optional support for avatars sitting on windows or the taskbar
Taskbar/window sitting is currently disabled to avoid triggering anti-cheat systems in certain games.
MateEngine is open-source. IIf you’re a developer or just curious about how it works, you're welcome to explore the project, contribute features, or build your own versions using Unity.
