Connect Overview

What is NVIDIA Omniverse™ Connect?

NVIDIA has built Extensions and additional software layers on top of the open-source USD distribution that allows digital content creation (DCC) tools and compute services to communicate with each other through the Omniverse Nucleus Database (DB). Those Extensions, additions, and the application plug-ins that make use of them are collectively known as NVIDIA Omniverse™ Connect.

Connect libraries allow client applications to connect to the Nucleus DB and to publish and subscribe to individual assets and full worlds. For typical existing DCC tools, most of the work in creating a proper plug-in to Omniverse is to establish a two-way synchronization between the scene representation in the USD library and whatever scene representation the tool uses internally. For applications that natively rely on the USD library, no such synchronization is necessary.

With any needed synchronization in place, a DCC plug-in will use the Connect libraries to apply externally received updates and publish internally generated changes as necessary. The Connect libraries make this particularly easy. As the application makes changes to its USD representation of the scene, Connect uses the built-in USD notification mechanisms to keep track of all the local changes since the last publishing event. When requested by the application, the Connect libraries will construct a file-by-file set of differences and publish them to the Nucleus DB where they will then be forwarded to all subscribers.

Connecting to Omniverse

There are multiple ways to interact with Omniverse from other applications, many of which are in real time and with automated material conversion:

Connectivity Description Examples
Bi-Directional Real-time updates are shared between participating applications after a single export/import. Material conversion supported. Epic Games Unreal Engine
Autodesk Maya
Autodesk 3DS Max

Uni-Directional Real-time updates from DCC application are reflected in OV. Changes in OV are not shared with host application. Material conversion supported. Graphisoft Archicad
Kitware Paraview

Autodesk Revit
McNeel Rhinoceros
Trimble SketchUp
ESRI CityEngine
Reallusion Character Creator

Reallusion Iclone

PTC Creo

Adobe Substance 3D Painter

SideFX Houdini

Export/Import Common formats via direct import or third-party app conversion to USD. Often, materials are manually converted. Export: FBX, GLB, GLTF, OBJ, OpenVDB, USDZ, USD
Import: 3D PDF, 3DS, 3DXML, 3MF, Dassault Systemes ACIS, Alembic, Dassault Systemes CATIA V4, Dassault Systemes CATIA V5, Collada, Autodesk DWF, Autodesk DWG, E57, IFC, IGES, Autodesk Inventor, Siemens JT, LXO, MD5, Siemens NX, Siemens Parasolid, PRC, PTC PRO/E, ShapeNet, Siemens Solid Edge, Dassault Systemes SOLIDWORKS, STL, STP, U3D, URDF, VDA-FS, VRML, X3D
Omni-Drive OmniDrive capable DCC apps allow for USD or Texture export. Similar to uni-directional, but no connector required. Adobe Substance 3D Designer

Installing Connectors

Use the Omniverse Launcher to install Connectors.

First, navigate to the Exchange tab:

Arrow pointing to the Exchange tab of the Omniverse Launcher

Select Connectors:

Arrow pointing to the Connectors filter of the Omniverse Launcher Exchange

From this menu, choose a connector to install:

Arrow pointing to the Connectors list of the Omniverse Launcher Exchange


Be aware, the host application must be present.

Finally, select Install and, provided you have a valid installation of the host application, the process will begin:

Arrow pointing to the Install button of the Connector
