Create Simple Low Poly Trees

Having a lot of trees in the game can really hit performance and is mostly a waste of resources, especially if the trees don’t require much detail. Creating simple trees and mass placing them is the perfect way to add some realism to the game without having a major impact on performance.

Although not very believable, it’s pretty okay if you’re not gonna get too close to it. The above models only have around 4 planes per tree and each plane has been rotated at an angle of 45° relative to the previous one.

To achieve the transparency in Blender, use the following nodes in Cycles.

The model can be used in Unity too, just remember to change the Standard Shader option from ‘Opaque’ to ‘Cutout’.
