[[File:Export_wavefront_obj.png|center]]

=== Introduction ===

Export selected objects to Wavefront .obj file format.

OBJ is a common 3d format, used to transfer data between applications.
Its an easy to parse text file format and well supported applications such as Maya, 3dstudio MAX, Wings3D and Lightwave.

=== Support ===

* [http://blenderartists.org/forum/forumdisplay.php?f=11 Python & Plugins forum] at Blender Artists (TODO).

=== Links ===

* [http://www.csit.fsu.edu/~burkardt/txt/obj_format.txt Obj format spec]
* [http://www.cis.uab.edu/info/grads/hux/Data/obj.html Sample Files]

== Usage ==

=== Instructions ===

Select the script from the File → Export menu and choose the filename to export to.

=== Configuration ===

These options will be presented at export time. in most cases the defaults should be good to use.

|-
|colspan="3"|Use transformed mesh data from each object. May break vert order for morph targets.
|-
|'''Rotate X90'''
|TOGGLE||'''ON'''
|-
|colspan="3"|Rotate on export so Blenders UP is translated into OBJs UP
|-
|'''Morph Target'''
|TOGGLE||'''OFF'''
|-
|colspan="3"|Disables options that will re-order the verts and faces, so it can be used as a morph target.
|-

|-
|colspan="3"|Export vertex normal data (Ignored by blenders importer but some programs use it)
|-
|'''High Quality Normals'''
|TOGGLE||'''OFF'''
|-
|colspan="3"|Use with normals, Calculates high quality normals good for rendering in cases where the normals are used.
|-
|'''UVs'''

|-
|'''Materials'''

=== Notes ===

* Only basic smoothing groups are supported using Blenders Smooth/Solid face property. per edge smoothing is not supported except through using the edge split modifier.

== Compatibility ==

Only mesh data is exported.

=== Supported ===

;Objects:
* Meshes: verts, edges, faces and uv coords.
* Metaballs
* Nurbs Surface
* Text
* Particles (strands as lines)

;Materials:
* RGB: diffuse, specular, ambient, emissive. Intensity: shininess, transparency.
* Images Texface and Material texture/images are supported. ''Faces with texface images are separated into their own materials''

=== Missing ===

;Other:
* The obj format has support for curves and nurbs, however these are exported as meshes.
* Vertex color is not supported by the obj format.
* The OBJ format only supports 1 set of UV coordinates, so only the active UV's will be exported.

== Known Issues ==

* Vue Esprit 5 and 6 will not import Blender OBJ files with edges, be sure to disable edge export when working with Vue Esprit.
