Advanced Foliage Shader v4 v4.1
“If possible, please buy the package to support the developer”
Place grass and foliage just everywhere in your game – be it on top of the terrain or any arbitrary mesh – and take advantage of all modern features of vegetation shading like procedural bending or physically based shading.
Now ready to be used with unity 5.
Make your vegetation react to any game object’s movement using touch bending, get perfectly lit grass and plants even on steep slopes or just benefit from the most beautiful fading billboards you have ever seen in unity 😉
[Demos are going to be updated, still from v.3]
