How to import an OBJ file into Blender?
- Click on File at the top left corner of the window > Import > Wavefront (.obj)
- Browse through the files to find your desired OBJ file (note that you will only be able to see and select OBJ files)
- Select Import OBJ

How do I open an OBJ file?
how to open a .obj file? Launch a .obj file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .obj file will open it. It's possible you may need to download or purchase the correct application.
How to import OBJ Blender?
Preparing a 3D model for mixed reality with Blender includes the following steps:
- Import the model into Blender.
- Decimate the model.
- Unwrap the model (UV unwrapping).
- Assign materials.
- Bake the textures.
- Export the model as a GLB file.
How to import Blender file?
- Go to “Edit Mode” and select all faces.
- Go to “Mesh > Normals > Recalculate Outside”.
- Save your file.
How to properly export to obj in Blender?
- Avatar attachments may not be imported as OBJ at this time.
- Objects exported as OBJ must currently use the Materials Settings window instead of Phong in order to set their textures.
- When exporting objects as OBJ from Blender, the scale must be set to 100 or the object will appear too small in Sansar.
Can you open OBJ files in blender?
Luckily, Blender offers a wide range of file formats (e.g. OBJ, FBX, 3DS, PLY, STL, etc.) that can be used to import and export. Popular formats are enabled by default, other formats are also supported and distributed with Blender, these can be enabled in the User Preferences through the use of Add-ons.
What is Blender OBJ file?
File ‣ Import/Export ‣ Wavefront (.obj) 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. Mesh: vertices, faces, edges, normals, UV's. Separation by groups/objects.
What is an OBJ file extension?
OBJ Files - OBJ (or . OBJ) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.Dec 15, 2020
What contains OBJ file?
The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.
What is an obj file?
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.
What direction does Blender use?
Blender uses Y Forward, Z Up (since the front view looks along the +Y direction). For example, its common for applications to use Y as the up axis, in that case -Z Forward, Y Up is needed.
What happens if there is a matching MTL for the OBJ?
If there is a matching .MTL for the OBJ then its materials will be imported too.
Can you split an OBJ file into Blender?
When importing an OBJ it’s useful to split up the objects into Blender objects, named according to the OBJ-file. However, this splitting looses the vertex order which is needed when using OBJ-files as morph targets. It also looses any vertices’s that are not connected to a face so this must be disabled if you want to keep the vertex order.
Is there a difference between OBJ groups and objects in Blender?
Note that as far as Blender is concerned there is no difference between OBJ Groups and Objects, this option is only included for applications which treat them differently.
Can an OBJ read an MTL file?
Write out the MTL-file along with the OBJ. Most importers that support OBJ will also read the MTL-file.
Do you need to write normals in Blender?
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.
What is an OBJ file?
OBJ files were first developed by Wavefront Technologies, a video graphics company specializing in animation software, but has since been adopted by other 3D vendors. OBJ files are essentially text files that contain the 3D object’s information in a plain text format.
Final thoughts
Overall OBJ files are a very useful file format for 3D objects due to its compatibility with most other 3D software. We have also gone through Blender’s simple method of importing and exporting OBJ files, and the various import and export options.

Can you export mesh objects in 3D?
Export mesh objects as seen in the 3D Viewport with all modifiers applied. Mostly you will want this unless you are exporting a subdivision surface cage.
Does Blender ignore normals?
Normals – Blender ignores normals from imported files, recalculating them based on the geometry.
