Recently, Adobe has started to introduce new and experimental features to the Substance 3D ecosystem starting with Substance 3D Sampler and Substance 3D Stager, aiming to bring creative freedom and faster workflows for industrial designers, 3D artists, and other professionals.
The latest Substance 3D Modeler 1.8.5 release in the Public beta program is no exception and introduced new Search by Shape and Smart Upres functions.
Asset library content can work as a good starting point or reference, or be useful as background content to help flesh out your scene. With Search by Shape, you can roughly block out objects, and then search the Substance 3D Assets library for parts with a similar shape, using keywords and checkboxes to refine the search if necessary.
