I love low poly scenes and for ages I would build my low poly trees by using a cylinder and extruding the end. Then copy the tree and rotate it... but this took ages. Then it dawned on me that using the skin modifier would be a much quicker way. So here it is a quick tutorial on how to make a low poly tree in blender.
- merge vertices
- extrude vertices
- copy and paste and re-merge vertices
- add skin modifier
- add sub.surf. modifier
Hope this helps you all and have fun Blendering
Here's the tree I made for the tutorial on Sketchfab:
