Indoor Scene

In this scenario we start with a model from Autodesk Revit that was imported using the Omniverse Connector. This scene will allow you to experiment with lighting, materials, and object placement.

The video below is a recorded example of this Launchpad lab with three designers collaborating on the kitchen scene. In this recording you can see them progressing through the lab as they apply materials, add lights and position props on the counters and shelves. Apply what you have learned in the outdoor scenario and expand your knowledge with the addition of lights and prop placement tricks like using snap and zero gravity placement.

Apply what you learned in Scenario 1 to an interior scene and expand on your skill set by experimenting with lights and render settings.

To set up the project for collaboration, designate one person to act as the project manager. This person will set up a shared project on the Nucleus server which will be used in this lab for collaboration. The project manager will execute the steps below.

1. Open Omniverse Create

2. Within the content tab, browse to /Projects folder within your Nucleus server.

3. Right click in the Browser pane, select New Folder and name it Indoor_Scene.

   

   
   

4. Double click on the new folder to open it.

5. Now let’s create a new project file, just to make sure we have a new blank file.

6. From the file pulldown, click on File > New.

7. Let’s get rid of the default scene light since we will be creating new lighting on a different layer in this project.

8. Click on the + next to the World (defaultPrim) then select defaultLight and press the Delete key on your keyboard.

   

   
   

9. Now let’s set up this project to be Z-up as our incoming file is from Rhino which defaults to Z-up. In general CAD applications use XY for the plan and Z for elevation (or Z-up) and content creation applications use XY for the screen and Z for depth (or Y-up).

10. Click the Layer tab and select the Root Layer.

11. Within the Property tab, change the World Axis to Z.

    

    
    

12. Click on File pulldown and select Save, then navigate to /Projects folder within your Nucleus server. Double click the Indoor_Scene folder and save your scene as Indoor_Scene.usd.

    

    
    

13. Now that we have a project file set up with the right World Axis, we will bring in a previously exported scene as a reference.

14. Make sure the Layer Tab is active in the upper right of Create.

    Note

    The Root Layer will be marked as Authoring Layer.

    
    

15. In the content browser (bottom left) navigate to the folder located at /NVIDIA/Demos/AEC/BrownstoneDemo/Worlds/ in your Nucleus server.

16. Click the file named World_BrownstoneDemopack_Brownstone(8Gb).usd and drag it into the Layers tab of your USD.

    Note

    The import may take several minutes during which Create may appear unresponsive. A blue progress bar will eventually appear in the bottom right corner of the Create window display to track loading progress.

    

    
    

17. Press F to frame the scene.

18. Press Shift+C and Shift+L to toggle camera and light objects off.

    

    
    

19. Now we will set the project up for better collaboration.

20. In the layer manager, right-click and choose Create Sublayer or click Add Sublayer Button.

    

    
    

21. Navigate back to your project folder /Projects/Indoor_Scene and enter the new Layer/USD File name in the bottom left, let’s go with AEC_Lighting_Option01.usd for this one, then click Save.

    

    
    

22. Create a few more layers using the same process.

    • AEC_Props_Option01.usd

    • AEC_Materials_Option01.usd

    

    
    

23. From the File pulldown select Save to save your Indoor_Collab.usd with these new work layers, these will make collaboration easier by keeping your edits to the design option layers organized.

24. The collaborative power of Omniverse fully shines when you enable Real Time Live Editing via Live Sync. This can be done on a per-layer basis, or for an entire project file. For this lab, when multiple collaborators open a project file at the same time, you should toggle on Live Sync for the entire project. This will allow you to see changes made on different VMs by your fellow collaborators in real time! Toggling on Live Sync is as easy as changing the Live Sync.

25. Within the layers tab, click on the live sync button.

26. Select Always On.
