Preparing 3D models

Support Staff
Updated

Follow these guidelines when preparing 3D models that won't be using Polygon Streaming.

Supported file formats

Unity Asset Bundle

VIVERSE for Business supports Unity standard and custom shaders, including animations.

Prepare AssetBundle files for all target platforms (‘*_windows.ab’, ‘*_android.ab’, and
‘*_ios.ab’) to allow users of VIVE XR Elite, VIVE Focus 3, and PC VR headsets, as well as
Android and iOS mobile devices to view your 3D model.

 

3D and image formats

Use any of the following supported 3D formats for your 3D model:

  • FBX (zipped)
  • GLB
  • glTF (zipped)
  • OBJ (zipped)
Note: Only BaseColor Map is supported.
 
If you want to create separate texture files for your 3D model, use any of the following supported
image formats for your textures:
  • PNG
  • JPG (baseline & progressive - 12 bpc/arithmetic not supported)
  • BMP (non-1bpp, non-RLE)
  • TGA

If your 3D model has separate texture files, the 3D model and textures must be packaged into a
ZIP file and then uploaded. If your 3D model doesn't have separate texture files, it doesn't need to
be packaged into a ZIP file. Your 3D model can be directly uploaded.

If you want to use an FBX model, the ZIP package should contain one .fbx file and all the texture
images in JPG or PNG format. Make sure they're properly set and connected. You can also
upload a single .fbx file if it has embedded textures.

 

Note: If the textures are not properly connected in your file, they will appear as plain white after
conversion. Only binary FBX files are supported. ASCII-based FBX files are not supported.

 

Recommendations and limitations

To ensure you can load your 3D model and others can see it, follow the recommended 3D model
specifications below.

For models that are not applying Polygon Streaming conversion, the recommendations are as follows:

 

PCVR

Standalone VR and mobile
Polygons 15,000 or below recommended 5,000 or below recommended, 200,000 maximum
File size 150 MB or below recommended 60 MB or below recommended, 300 MB maximum
Texture
resolution 		4096 x 4096 or below
recommended		 1024 x 1024 recommended, 2048 x 2048 maximum

 

For models that are applying Polygon Streaming conversion, the recommendations are as follows

Polygons Single 3D object suggested spec:
  • Range of Polygon count between 1M to 30M
Minimum suggested single 3D object spec:
  • >150k Polygons with texture maps and materials
File size Polygon Streaming Standalone:
  • Free Plan: 500MB
  • Enterprise: Custom
    • Please contact us here for more information
VFB:
  • No restriction on upload cap
Texture
resolution 		Between 1 to 50 texture maps with resolutions between 2K to 4K
