Downloading materials


I have just started to use Rhino render for the first time and found these wood materials that I would like to use but am struggling to get them into Rhino. I have got them in my downloads but how do I get them into use on Rhino?

I run a mac if that makes any difference.

Many thanks,


Those are materials for Brazil, not for Rhino itself…
Brazil is a rendering plug-in.

Ah ok, are there any good source for free wood materials, looking at getting some veneer sufaces on furniture.

Many thanks
