Available 3D formats

在处理 3D 资产时,Godot 有一个非常灵活且可配置的导入器。

Godot works with scenes. This means that the entire scene being worked on in your favorite 3D modeling software will be transferred as close as possible.

Godot 支持以下 3D 场景文件格式

  • glTF 2.0 (recommended). Godot has support for both text (.gltf) and binary (.glb) formats.

  • .blend (Blender). This works by calling Blender to export to glTF in a transparent manner (requires Blender to be installed).

  • DAE (COLLADA), an older format that is supported.

  • OBJ (Wavefront) format + their MTL material files. This is also supported, but pretty limited given the format's limitations (no support for pivots, skeletons, animations, UV2, PBR materials, ...).

  • FBX, supported via FBX2glTF integration. This requires installing an external program that links against the proprietary FBX SDK, so we recommend using other formats listed above (if suitable for your workflow).

Copy the scene file together with the textures and mesh data (if separate) to the project repository, then Godot will do a full import when focusing the editor window.

Importing .blend files directly within Godot

备注

This functionality requires Blender 3.0 or later. For best results, we recommend using Blender 3.5 or later, as it includes many fixes to the glTF exporter.

It is strongly recommended to use an official Blender release downloaded from blender.org, as opposed to a Linux distribution package or Flatpak. This avoids any issues related to packaging, such as different library versions that can cause incompatibilities or sandboxing restrictions.

From Godot 4.0 onwards, the editor can directly import .blend files by calling Blender's glTF export functionality in a transparent manner.

This allows you to iterate on your 3D scenes faster, as you can save the scene in Blender, alt-tab back to Godot then see your changes immediately. When working with version control, this is also more efficient as you no longer need to commit a copy of the exported glTF file to version control.

To use .blend import, you must install Blender before opening the Godot editor (if opening a project that already contains .blend files). If you keep Blender installed at its default location, Godot should be able to detect its path automatically. If this isn't the case, configure the path to the directory containing the Blender executable in the Editor Settings (Filesystem > Import > Blender > Blender 3 Path).

If you keep .blend files within your project folder but don't want them to be imported by Godot, disable Filesystem > Import > Blender > Enabled in the advanced Project Settings.

The .blend import process converts to glTF first, so it still uses Godot's glTF import code. Therefore, the .blend import process is the same as the glTF import process, but with an extra step at the beginning.

备注

When working in a team, keep in mind using .blend files in your project will require all team members to have Blender installed. While Blender is a free download, this may add friction when working on the project. .blend import is also not available on the Android and web editors, as these platforms can't call external programs.

If this is problematic, consider using glTF scenes exported from Blender instead.

从 Blender 导出的 DAE 文件

Blender has built-in COLLADA support, but it does not work properly for the needs of game engines and shouldn't be used as-is. However, scenes exported with the built-in Collada support may still work for simple scenes without animation.

For complex scenes or scenes that contain animations, Godot provides a Blender plugin that will correctly export COLLADA scenes for use in Godot.

Importing OBJ files in Godot

OBJ is one of the simplest 3D formats out there, so Godot should be able to import most OBJ files successfully. However, OBJ is also a very limited format: it doesn't support skinning, animation, UV2 or PBR materials.

There are 2 ways to use OBJ meshes in Godot:

  • Load them directly in a MeshInstance3D node, or any other property that expects as mesh (such as GPUParticles3D). This is the default mode.

  • Change their import mode to OBJ as Scene in the Import dock then restart the editor. This allows you to use the same import options as glTF or Collada scenes, such as unwrapping UV2 on import (for 使用光照贴图全局照明).

备注

Blender 3.4 and later can export RGB vertex colors in OBJ files (this is a nonstandard extension of the OBJ format). Godot is able to import those vertex colors since Godot 4.0, but they will not be displayed on the material unless you enable Vertex Color > Use As Albedo on the material.

Vertex colors from OBJ meshes keep their original color space once imported (sRGB/linear), but their brightness is clamped to 1.0 (they can't be overbright).

Importing FBX files in Godot

When opening a project containing FBX scenes, you will see a dialog asking you to configure FBX import. Click the link in the dialog to download an FBX2glTF binary, then extract the ZIP archive, place the binary anywhere you wish, then specify its path in the dialog.

If you keep .fbx files within your project folder but don't want them to be imported by Godot, disable Filesystem > Import > FBX > Enabled in the advanced Project Settings.

The FBX import process converts to glTF first, so it still uses Godot's glTF import code. Therefore, the FBX import process is the same as the glTF import process, but with an extra step at the beginning.
