Common types of assets

이미지 파일

Unity supports most common image file types, such as BMP, TIF, TGA, JPG, and PSD. If you save your layered Photoshop (.psd) files in your Assets folder, Unity imports them as flattened images. You can find out more about importing images with alpha channels from photoshop, or importing your images as sprites

FBX 및 모델 파일

As Unity supports the FBX file format, you can import data from any 3D modeling software that supports FBX. Unity also natively supports importing SketchUp files. For information on how to get the best results when exporting your FBX files from your 3D modeling software, see Optimizing FBX files.

Note: You can also save your 3D files from most common 3D modeling software in their native format (for example, .max, .blend, .mb, .ma). When Unity finds them in your Assets folder, it imports them by calling back to your 3D modeling software’s FBX export plug-in. However, it is recommended to export them as FBX.

메시 및 애니메이션

사용하는 3D 소프트웨어 모델과 관계없이 Unity는 메시와 애니메이션을 각 파일에서 임포트합니다. Unity가 지원하는 3D 모델링 소프트웨어의 목록은 모델 파일 포맷에서 확인할 수 있습니다.

애니메이션이 없는 메시 파일도 임포트할 수 있습니다. 애니메이션을 사용하는 경우 파일 하나에서 모든 애니메이션을 임포트하거나 애니메이션이 하나씩 포함된 개별 파일을 임포트할 수 있습니다. 애니메이션 임포트에 대한 자세한 내용은 모델 임포트 워크플로를 참조하십시오.

오디오 파일

If you save uncompressed audio files into your Assets folder, Unity imports them according to the compression settings specified. Read more about importing audio files.

Other asset types

In all cases, Unity never modifies your original source file, even though you can often choose between various ways to compress, modify, or otherwise process the asset within Unity. The import process reads your source file, and creates a game-ready representation of your asset internally, matching your chosen import settings. If you modify the import settings for an asset, or make a change to the source file in the Assets folder, that causes Unity to re-import the asset again to reflect your changes.

Note: Importing native 3D formats requires that the 3D modeling software be installed on the same computer as Unity. This is because Unity uses the 3D modeling software’s FBX Exporter plug-in to read the file. Alternatively, you can directly export as FBX from your application and save in your project folder.

스탠다드 에셋

Unity ships with multiple Standard Assets. These are collections of assets that most Unity customers use. These include:

  • 2D
  • Cameras
  • Characters
  • CrossPlatformInput
  • Effects
  • Environment
  • ParticleSystems
  • Prototyping
  • Utility
  • Vehicles

To transfer Standard Assets in and out of projects, Unity uses Asset packages, available on the Unity Asset Store. Asset packages allow you to share and re-use Unity projects and collections of assets.

Note: You can download Standard Assets from the Asset Store.

Unity 패키지 관리자의 에셋

You can install a wide range of assets, including plug-ins, tools, and libraries directly into Unity through the Unity Package Manager (UPM). These are a new type of package, and are available through the Package Manager window. For more information about packages in general, see the Packages documentation.
