As of May 31, 2023, we have updated our Code of Conduct.

Questions tagged [obj]

OBJ (or Wavefront) files are plain text files that contain 3D geometry data. Blender can import from and export to this format. This tag is specifically for questions about using files with a '.obj' extension with Blender and is not to be used for general 'object' questions.
