I know that many people have been struggeling to create good low poly trees for a while now. There are some tutorials on youtube about this topic, but i always felt that they were lacking the quality of what people actually want to create.
So here I created a small 4 part tutorial series, which shows 4 different techniques to create good looking lowpoly trees. They should be usable for beginners, since i tried to explain everything as detailed as possible, but they also introduce you to some more advanced techniques like curves, metaballs, group instances and the skin modifier. So there is a lot new to learn about!
Have fun with them and feel free to ask any question!
Note that this is a four-part video playlist.
