A 3D model of a grass pack with realistic textures and low poly count is ideal for use in AR/VR and gaming environments. The model should be optimized for performance, meaning it should be efficient and not require too much processing power to render.

The grass blades should be designed with a low poly count, meaning they have a minimal number of polygons to ensure smooth performance. However, the blades should still look realistic and well-textured, with variations in shape and size to add visual interest. The blades should also have alpha channels to allow for transparency, which is necessary for realistic-looking grass.

Additionally, the grass model should be compatible with different platforms and engines. The model should be optimized for Unity or Unreal Engine and should be exported in a format that can be easily imported into these game engines. It should also be ar/vr ready to allow for integration into AR and VR applications.
