This game ready asset provides you with all the grass foliage you need, as well a multi-layered Landscape Material.
Welcome to the release post of our new dynamic optimized grass asset for the Unreal Engine! In the following parts the important parts like animation or optimization methods will be displayed and explained.
A lot of information about the creation process are discriped in an interview I prepared together with **80.lv **If you are interested, just klick the link below:

The goal of this asset is to offer an affordable grass asset with great visual quality and best possible wind animation with a good optimization for performant usage in games and even for cinematic scene rendering.
First of all, if you have any questions about this product feel free to contact me via mail ProjectNature@outlook.de and I will do my best to answer your questions!
For the animation creation we used the Pivot Painter tool 2.0. This results in a unique animation for each blade of grass. Cause this animation is generated in the shader it is as performant as using the “SimpleGrassWind” node. All wind parameters are easy adjustable and well explained in the dokumentation. You can choose from soft wind to hard wind, all possible wind directions and even dynamic bending of objects.
Quad overdraw and shader complexety for foilage is a big thing. Most of the time a lot of performance is lost cause of this reasons. In this asset we tried to find the best balance between vertex count (object like geometry) and alpha overdraw (easiest geometry). The results can be seen in the picutre and vide below:
