Accepted file formats for 3D and Augmented Reality

How to make compatible 3D files to use them on Numerized? And how to export your 3D assets?

Accepted 3D file formats:

  • .obj
  • .ply
  • .fbx
  • .gltf
  • .glb

Maximum file size (including textures):

  • 3 MB for maximum compatibility and acceptable loading times for the user.
  • 8 MB to use the 3D player (not compatible with Augmented Reality).

Number of polygons:

For maximum compatibility, it is recommended not to exceed 75,000 polygons (ideally less than 50,000 polygons).


Numerized’s 3D viewer can manage PBR (Physically Based Rendering). This allows you to manage different materials on a single 3D model. It is strongly recommended to accompany your 3D models with the following textures:

  • Albedo
  • Roughness
  • Metallic
  • Diffusion

UV Map:

It is recommended to limit the number of UV Map to 1. Each new addition of UV Map will increase the model’s file size.

3D model animation:

Here are the types of 3D model animation that can be integrated into the 3D model (avoid creating excessively long animation loops):

  • Skeletal animation loop
  • Rigid animation loop
  • Transform animation loop

Important: Only the first animation included in the 3D model will be played in AR Mode.

Real-world scaling:

To be able to be used in augmented reality, the 3D model must be scaled to the real world: 1 unit of measurement = 1 meter.
Real world scaling is available in the Numerized dashboard.
