You can upload a 3D model to a Cisco Spark space in order to visualize it in 3D in Cisco Spark in VR. 

The only currently supported file format is Wavefront's objformat. There are two ways to upload a model:

1. Standalone OBJ.

Just uploading a single obj file into the Space will render the model in VR with the default white material/texture. 

2. "Packaged" OBJ. 

Alternatively, you can view a textured model by uploading the obj  file, its associated material file (mtl) and any images (png) that its material references. The image filenames must match what is expected by the material. 

Note: It is import to upload all associated files in a single message.
