Intro to Node Groups
The node system in Blender is very powerful gives unrivaled flexibility when it comes to creating shaders and compositing effects. One of the node systems most powerful features, though, is it’s ability to group nodes together. By grouping nodes we can effectively create custom, reusable nodes. This works by grouping sets of nodes together and then exposing specific settings, inputs, and outputs from the nodes within the group. By using node groups you can create complete libraries of shaders and compositing effects which can be linked or appended into any scene you’re working on.

Nature Academy: Box of Goodies
I’ve realized that the only way to create realistic outdoor scenes is by adding lots and lots of nature elements. Things like trees, flowers, bushes, rocks etc. are essential in making the scene look “believable”. But I also know that creating these things by hand takes a very long time. And not everyone has time to sit down for hours on end and create tree after tree after tree. Which is why I’ve done the hard work for you :) The Box of Goodies! Inside this box of goodies you’ll find 9 nature models that you can keep. As well as this you’ll find a collection of grass reference photos that will help you to better create it in blender. Eg. What will you do with yours? Drop your email address in the box to the right and I’ll send the Box of Goodies your way.
