Warehouse Physics


This tutorial teaches you how creators can connect their favorite applications to NVIDIA Omniverse. To accomplish this task, we’ve created a series of videos which help you gain an understanding of the Omniverse workflow.

The first 8 videos show you the creative process, with the last step showing you how to simulate and interact with the final stage.

We highlight how to use Connectors to sync to live changes between Omniverse USD Composer and Adobe Substance 3D Painter, AutoDesk 3dsMAX and Maya. For this project, we have created assets to populate a warehouse. Then, in Create, we setup physics for the racks, boxes and hanging lamps. This workflow highlights how quickly creators can generate compelling pre-viz and final physics-based animations inside Create.

The video below gives a quick overview of how you can interact with this stage.

Step 1: Connect to Nucleus

If necessary, launch Omniverse USD Composer and then Connect to Nucleus Server


You must enable the “PhysX FlatCache” extension before loading the stage

Step 2: Navigate to the extension

Go to Windows > Extensions


Step 3: Find and enable the extension

Search for flat and enable the PhysX FlatCache extension


Step 4: Open the Stage

Load the stage file at the following path: omniverse://omniverse-nucleus.nvidialaunchpad.com/NVIDIA/Demos/WarehousePhysics/Worlds/World_Demopack.usd. Choose Open Original file and Wait for the stage to load (blue progress bar in the lower right corner)

Step 5: Declutter the viewport

You can press SHIFT + H to activate “declutter” mode which hides all icons and gizmos in the viewport

Step 6: Play the simulation

Press spacebar or click the Play button to start and pause playback


Use SHIFT + Left Click Drag to move objects while the stage is playing back. You can use this to pull shelves and boxes around during playback. To stop the simulation and reset the stage, press the Stop button.
