Vibrant Grass Shader

⭐ Key Features ⭐ :

• Very Beautiful
• Excellent Performance
• Performant Lights and Interactions : Over 50 objects can be used as point lights and can interact with the grass (the grass is pushed aside with a sound effect when moving through it). It technically can get up to 1000 objects but the performance drop gets serious after about 50.
• Customization : Paint shadows, height, colors and modify many material properties.
• Color Masks : Painted colors can be changed after applying them - Very handy if you change your mind.
• Professional UI : Simple and intuitive design, use a brush wheel and shortcut keys while painting.
• Audio tool : Easily make the grass area continuously emit a sound effect (useful to simulate the sound of the wind moving the grass).
• Fast customer support : On a normal week, you should get an answer within 1-2 days.
• Hill collisions : There is a system to prevent the wind from pushing the grass through the ground (works best on smooth grounds).
• Interaction Height : The interaction objects push only grass stalks that are taller than the lowest height of the object (works approximately). Useful for hovering objects.
• Shader Graph : The Shader uses Unity's Shader Graph so you can easily add custom features.
• Blends well with the HDRP Volumetric Fog
• You can wrap the grass onto any collider including Unity terrains

✖️ Limitations :

• Creation Time : It takes time to wrap the grass onto the ground (a couple of seconds per 15x15 meters grass field, depending on your computer), and to paint heights and shadows. It was tested on a PC and took 1min to wrap a 75x75meters area and 10mins for 300x300meters, but it depends on your computer. Please check the "Setup" file for a few advices before working on a large area.
• Unlit materials, Manual Shadows : Painting shadows manually is great for customization and performance, but takes time and has to be done in edit-mode. There is no official way to make the grass react to Unity's lights and shadows.
• Setup in edit mode : The grass has to be setup and wrapped onto the ground in edit-mode.

Please read the "Setup.pdf" found in the package before using the asset.
