OBJ is a widely used de facto standard in the 3D industry. The OBJ format is a popular plain text format, however, it has only basic geometry and material support.

Ghi chú

There is no support for armatures, lights, cameras, empty objects, parenting, or transformations. See Compatibility for more information.

Sử Dụng (Usage)

Export geometry and curves to the OBJ format.

Xuất Khẩu (Exporting)

Tính Chất (Properties)

Hoạt Họa (Animation)

Animation (Hoạt Họa)

Exports a numbered OBJ for each frame from the start to the end frame. Please be aware that this can take quite a long time.

Khung Hình Khởi Đầu, Kết Thúc (Frame Start, End)

The first and last frame to export, used to determine the range of exported frames.

Tính Chất của Vật Thể (Object Properties)

Axis Forward, Up

Since many applications use a different axis for 'Up', there are axis conversion settings, Forward and Up axis -- By mapping these to different axis you can convert rotations between applications default up and forward axis.

Blender dùng Y Hướng Trước, Z Hướng Trên (vì góc nhìn từ đằng trước vọng dọc theo chiều +Y). Lấy ví dụ, việc trình ứng dụng sử dụng Y làm trục hướng lên trên là điều thông thường. Trong trường hợp này, -Z Hướng Trước, Y hướng Lên Trên là điều cần thiết.

Tỷ Lệ (Scale)

Global scale to use on export.

Duy cái được Chọn (Selected Only)

Only export the selected objects. Otherwise export all objects in the scene.

Tính Chất (Properties)

For properties that have different settings for the viewport/final render pick which is used for output. One example where this is important is the Bộ điều chỉnh phân hóa bề mặt (Subdivision Surface Modifier).

Viewport (Default)

Use viewport properties.

Render (Kết Xuất)

Use final render properties.

Geometry Export

Tọa Độ UV (UV Coordinates)

Write out the active UV layers coordinates from Blender.

Pháp Tuyến (Normals)

Write out Blender's face and vertex normals (depending on the faces smooth setting).

Mostly this isn't needed since most applications will calculate their own normals but to match Blender's normal map textures you will need to write these too.

Nguyên Vật Liệu (Materials)

Write out the MTL-file along with the OBJ. Most importers that support OBJ will also read the MTL-file.

Triangulated Mesh

Write out quads as two triangles. Some programs only have very basic OBJ support and only support triangles.

Đường Cong thành NURBS (Curves as NURBS)

Write out NURBS curves as OBJ NURBS rather than converting to geometry.

Nhóm Lại (Grouping)

Nhóm Vật Thể(Object Groups)

Write out each Blender object as an OBJ object.

Ghi chú

Note that as far as Blender is concerned there is no difference between OBJ Groups and Objects, this option is only included for applications that treat them differently.

Nhóm Nguyên Vật Liệu (Material Groups)

Create OBJ groups per material.

Nhóm Điểm Đỉnh (Vertex Groups)

Export the name of the vertex group of a face. It is approximated by choosing the vertex group with the most members among the vertices of a face.

Các Nhóm Mịn (Smooth Groups)

Write Blender's sharp edges as smooth groups.

(Bitflag Groups)

Generate Bitflags for smooth Groups.

Nhập Khẩu (Importing)

Importing OBJ-files is currently handled by a python importer which is included as an addon. It's documentation can be found here: OBJ Importer </addons/import_export/scene_obj>.
