ArchiCAD’s rendering engine is Lightworks and, although it comes with some internal material libraries, it’s always nice to have more. Lightworks has therefore set up a website where users can download additional libraries – most of them free. Look for those that have “Base functionality” or “Architectural functionality” – the others may not work.
