Blender Market: ProWood Procedural Wood Shader Pack

Procedural shaders are great for shading complex models as they have a volumetric material model. They can be hard to set up though, so maybe this procedural wood pack can help.
Karl Andreas Groß writes:Shading complex wooden models can be a frown, and often wood textures are of bad resolution or expensive to buy. And even for larger Floors, the resolution of the image textures is often to low to render high resolution images.
To end up with this, this procedural Wood Shader Pack gives you a smart and easy solution. You will get a realistic looking, fully procedural Pack of wood shaders, which makes it easy to shade every wooden model, regardless of size and complexity.
The Pack comes with six preinstalled Wood Types (Oak, Beech, Olive, Teak, Cherrywood and Walnut), als well with three types of usage specifications: A setup for solid wooden Objects, a setup for plane based Floors, and a third one for Floors made with the Blender Floor Generator Addon.
Along with the Pack you will get a free Bonus Example of two Wooden Cabinets, already Shaded with the ProWood Shaders.
The Pack also comes with full detailed, 20 Page PDF Documentation, in which every single Shader Setting is explained via Shadings examples and Text.
