Hello. I'm trying to render using Lightworks for the first time I'm using a wood material that I'm not too happy with but all the others are a darker wood type. is there somewhere you can download materials to lightworks?
There's also a book "LightWorks in Archicad" that deals extensively with materials [surfaces]. See below for ordering.
As for your specific issue, a hidden feature of LightWorks is a non-implemented material archive. The attached dialog composite shows how to access a LightWorks 'shader' in this archive offering a variety of wood types. A 'shader' is merely a programmed pattern generator.
