unity terrain grass shader

OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE Using a rendertexture technique I made up a shader to bend grass with a particle system. The shader will take an input mesh, and from each vertex on the mesh generate a blade of grass using a geometry shader.To create interest and realism, the blades will have randomized dimensions and … IN NO EVENT SHALL THE The base of the grass gets its color from the underlying terrain’s texture, and the tip of the grass is a user-specified color. The grass is now rendered on the terrain depending on the strength of the corresponding terrain texture. The "Material" slot of the script needs to be filled with the "Grass Shader Deferred" material. There are several methods to populate a terrain with grass in Unity, this section outlines them and their (dis)advantages. To configure the shader, select the "Grass Shader Deferred" material found in "Terrain Shader/Shader". for the player character to bend the grass where he walks). A terrain can have grass clumps and other small objects such as rocks covering its surface. The alternating patches of grass are considered “healthier” at the centers than at the edges, and colors set in the Healthy Color and Dry Color settings represent the health of the grass. I would think those could change a bit for HDRP. When the script is added to the model, "Radius" specifies the maximum radius where grass is bent. Terrain with grass Enabling details The Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. I ask because cant get grass etc to work on it, so what is everyone else doing? You can add the "Terrain Shader/Shader/GrassCollider.cs" script to the player character model (or any other object) to make the grass bend in a circle around it. Creating bumped / specular shaders as above is fairly straightforward because Unity already comes with a bumped specular terrain shader – you just need to specify a material that uses it in place of the default diffuse terrain shader. If you blend two terrain textures the grass assigned to each texture blends depending on the strengths of each texture.
