Blendermada means Blender material database
Blendermada's mission to create good material database for Blender for all popular render engines and share it with all.
All materials here made by administrator and volunteers, and published under CC-0 license. It means you can use it anyway you want.
Blendermada is free and open. But hosting where Blendermada is placed isn't. Every month I take expences to keep Blendermada alive, and they increases with number of users. If you want to keep Blendermada available and fast working, you can donate some money to share that expenses.
