The provided Lumion Library Materials and Objects are limited also, so that the file size is reasonable for download.
The main area of use for materials though is in using the Custom Materials (first one, top left icon). This one allows you to edit materials when a model is imported as well as add your own materials, textures and settings to those. For example you make windows of buildings using the Glass Material (one of 9 sub-materials of the Custom type), create Standard Materials where you can add your own texture, Color Material etc.
