Brio has its own library of objects and materials that may be accessed and used to build a scene. The object library contains primitive objects including structures and instructional areas intended for product presentation. The library also has access to Gpoly’s - a collection of open-sourced 3D models from Google.
User libraries and material libraries can also be accessed from the materials panel.
