With Google Poly you can import thousands of free models from Google Poly directly into your project or add your own models from Blocks/TiltBrush. The library of Poly assets is growing quickly and provides an easy to use source of low-poly assets to use in Sketchbox.
TiltBrush and Blocks are great creative tools, and any model or scene you create with them can be easily imported into Sketchbox via Google Poly. The best way to find models you've uploaded to Poly is to give them a specific pre-fix or suffix when you upload them to poly. Then do a search in Sketchbox for that pre-fix or suffix and all of your models will appear. See video below:

Or you can download the model files from Poly, and add them to your Sketchbox Mesh Folder: %USERPROFILE%/Documents/Sketchbox/Import/Mesh or C:\Users\<your-user-name>\Documents\Sketchbox\Mesh.
