Every Unity developer eventually hits the same wall: “I can code the mechanics, but I can’t model a dragon.”
The Unity Asset Store is an incredible resource, but it isn’t the only place to find gold. In fact, relying solely on it can sometimes make your game look like a “default Unity project.” To give your game a unique visual identity—without spending a fortune—you need to know where to look.
Here is your ultimate guide to the best websites for downloading game assets in 2024-2025, and more importantly, how to actually get them working in Unity.
1. The General Heavyweights
Best For: Indie, stylized, pixel art, and experimental assets.
Price: Mostly free or “Pay What You Want” (PWYW).
Why it rocks: Itch.io is the heart of the indie community. You will find unique, quirky assets here that don’t exist anywhere else. It is especially legendary for 2D pixel art sprites and UI packs.
Best For: Completely free, open-source content.
Price: Free.
Why it rocks: It’s not the prettiest website, but it is a goldmine. Everything here is free, often under licenses that allow you to modify them. It’s perfect for placeholder art or prototyping.
Best For: Prototyping and consistent low-poly styles.
Price: Free (CC0 – Public Domain).
Why it rocks: Kenney is a legend in game dev. He offers thousands of assets (3D, 2D, UI, Audio) that all share a consistent art style. You can build an entire prototype in minutes using just his packs.
2. Specialized 3D Model Sites
When you need a specific prop, character, or environment.
Best For: High-quality, artistic 3D models.
The “Gotcha”: Sketchfab is a gallery first, marketplace second. Not everything is downloadable. Look for the “Downloadable” filter when searching.
Unity Tip: Sketchfab has a dedicated Unity Plugin that lets you search and import models directly inside the Unity Editor, saving you from messing with file extraction.
Best For: Professional, realistic, AAA-quality models.
Price: Paid (often expensive).
Unity Tip: These sites are geared toward general 3D professionals (movies, architecture). Always check if the model is “Game Ready” (low poly count) before buying!
3. Textures & Materials
To stop your 3D objects from looking like grey blobs.
Best For: Ultra-realistic textures and HDRIs (Skyboxes).
Price: 100% Free (CC0).
Unity Tip: Their HDRIs are essential for lighting your scene. Drag an HDRI into your Unity project, create a new Material, set it to “Skybox/Cubemap,” and apply it to your Lighting settings to instantly make your game look professional.
Best For: Seamless PBR (Physically Based Rendering) textures.
Unity Tip: When you download a material here, you will get multiple images (Color, Normal, Roughness, Displacement). In Unity, you create a Standard Material and drag these images into their respective slots to get that realistic “bumpy” look.
4. Audio (SFX & Music)
Because a silent game feels broken.
Best For: Raw sound effects (footsteps, heavy machinery, ambient nature).
Unity Tip: Files here are often .wav or .mp3. Unity accepts both. For short sounds (gunshots), set the import setting to “Decompress on Load.” For long music, set it to “Streaming” to save memory.
The Crucial Part: Licensing
Before you download anything, check the license. Using the wrong asset can get your game sued or removed from Steam.
| License Type | Can I use it in a commercial game? | Do I need to credit the author? |
| CCO (Public Domain) | Yes | No (But it’s nice to do so) |
| CC-BY (Attribution) | Yes | Yes (You must credit them in your game) |
| CC-NC (Non-Commercial) | No | Yes |
How to Import These Assets into Unity
Since these aren’t from the Unity Asset Store, they won’t automatically appear in your Package Manager. Here is the manual workflow:
- Download & Extract: Unzip the file on your computer.
- Clean Up: Delete files you don’t need (like the
.blendfile if you only need the.fbx, or the text files) before importing to keep your project clean. - Drag & Drop: Open Unity. Drag the folder containing your assets directly from your computer into the Project Window (bottom panel).
- Check Import Settings:
- For 3D Models: Click the model in Unity. In the Inspector, check the “Materials” tab. You may need to click “Extract Materials” if the model looks grey.
- For Sprites: Click the image. In the Inspector, change “Texture Type” to “Sprite (2D and UI)” and hit Apply.
Happy hunting! Your dream game is just a few downloads away.
