Importing 3D Objects as Props in Previs Pro

Custom models can help define key elements of your project, be it a unique location, that Maltese Falcon set piece, or simply the requirement to include specific client IP. If the PropGen built in AI doesn't work for you, import Props from Fab.com, your devices LIDAR scanner, your VFX team and more!

‍IMPORTING PROPS FROM FAB.COM

In Previs Pro, tap the Pencil from the main screen.

  1. Tap "Import", then select "Import 3D Props."
  2. Tap the Magnifying Glass in the upper right to switch to a browser and search for a 3D Prop on Fab.com  (Suggested size under 100mb, 150 max; under 250k Triangles, 400 max.)
    1. Choose the 'glTF' format, which should always be the default option.
    2. The file (a .zip) will have been saved in your Files downloads on your device, where you can load it into Previs Pro using the procedure below.

IMPORTING A 3D PROP FROM THE LIDAR SCANNER ON YOUR DEVICE

  1. There are many LiDAR capture apps on the App Store (we use PolyCam but there are dozens.)  Find one and save the scan to the Files on your device as “GLTF.”  It sorta… MAGIC!  
  2. Make sure the scanned object isn’t too complex, it might take some playing with to get the hang of it.
  3. The result will be impressionistic but 100% size accurate.  In many ways this is better for storyboards, you’re evoking the scene, not filming it.  Using 100% accurate sets and props is especially powerful combined with Augmented Reality.
  4. Import the file using the following instructions and you should be all set.
  5. See tool suggestion below for reducing model size after it’s generated.

IMPORTING A 3D PROP FROM THE FILES ON YOUR DEVICE

1. Tap the Pencil from the main canvas screen.

2. Tap "Import", then select "3D Props"

3. Tap the Folder in the upper right to bring up the file picker.

4. Select the 3D Prop to import.  (Note: If you can’t select your prop, ZIP it and any files it came with and try selecting the zip file.)

5. If successfully loaded, you’ll be able to adjust the objects "facing" and "scale.”  This is for your convenience and to help us optimize the object.  (If you're importing a banana it needs less detail then if you're importing a car).

6. Tap "Done" and Previs Pro will optimize the prop object, and drop it into your shot!

HOW TO HAVE A GOOD EXPERIENCE

“3D objects” in computers are a complicated topic. They can range from tiny to gigabytes in size, include animations and fancy lighting effects; a Minecraft block to the Mandolorian. So don’t expect it to be as simple as using images.  Results will vary; not all models are compatible or free. If you attempt too large a file, the app may be closed by the OS (all work will be saved!) and need to be relaunched.

Suggestions for searching: Use terms like “downloadable” or “low poly.” If you find assets made for games, they are usually smaller and work well. And finally, there are lots of 3D Artist’s looking for side gigs, make friends and commission what you need.  Here’s a place to start: Upwork 3D Modelers.

Note: We recommend a minimum of 4GB device to use imported props. Check your device specs, or see here.
