Creating stylized 3D trees can be a challenge. Fortunately for you, Blender makes it easy to make low poly trees in any shape you want. The skin modifier makes it possible to quickly create endless variations very quickly without sculpting or endless box modeling.
In this Blender tutorial we will go through the process of creating a tree from a single vertex to adding branches and leaves with particles. In the end you will have a semi-realistic tree that you can leave as is or take it even further with sculpting or displacement.
