Technical Guidelines


Here are some tips for making 3D designs that run smoothly on mobile devices:

  • Please upload your files (model, textures, and others) as zip or rar file. Do not upload more than one zip or rar.
  • Do not include more than one 3D model file in the zip (e.g. two FBX files or two Unity files)
  • Please optimize 3D models and textures for mobile. Suggested max polygon count: 50K, max size for all texture files: 15MB.
  • 3D object direction should be +y forward.
  • Surface normals have to be checked. (If reversed, it will not be displayed on the screen.)
  • Object format can be obj / fbx / dae.
  • All simulations such as particle effects and rigid bodies in Unity can be used, but the Leo AR system does not support shader.cs or scripts.
