We just created our own personal procedural tiny planet shader!.. "Unity", Unity logos, and other Unity trademarks are trademarks or registered trademarks of Unity Technologies or its affiliates in the U.S. and elsewhere (, Is designed to work with the Scriptable Render Pipeline feature. Required fields are marked *. The 2D terrain textures just use the objects UVs but since it is a CubeSphere with the UV mapping of a cube there is still one seam in the 2D textures at the top or bottom face of the cube.. The graph framework shows you the effects of your actions as you work. You dont need to know how to write code to create shaders. Not only do we give the user of the shader control over those properties this way, we can also decide what the values should be on a per-material basis without having to create multiple shader graph variants, which is cool if were going to procedurally generate different planets later on! Learn how your comment data is processed. These auto generated normal maps are usually not as superb as hand-crafted fine-tuned normal maps but definitely better than nothing! How to draw lines, circles or anything else using Line Renderer, Shader Development Tutorials From Scratch, The Big Shader Graph Tutorial: Introduction, The Big Shader Graph Tutorial: Second Part, The Big Shader Graph Tutorial: Third Part, Forcefield Shader using Shader Graph in Unity3D. A Shader Graph enables you to build your shaders [] By using exposed Enum Keywords we can switch between different noise nodes in our graph: (At the time of writing this the enum keyword functionality of Shader Graph is kind of buggy, sometimes it works and sometimes it doesnt so use this at your own risk.. Ive found that sometimes after creating an enum it would work until I changed a reference name or reference suffix from one of the enum entries so it might take a couple of retries before it works. Here you can see the difference in one octave of Simplex noise and layered simplex noise with two and three octaves: To create biomes for our planet we can use the separate RGB channels of a gradient that we sample over the y-axis of the Position for three different biomes. You create and connect nodes in a network graph instead of having to write code. !In this tutorial we will create a procedural planet shader using Unitys node-based shader creation tool Shader Graph. Then we divide it by the Displacement Amplitude to evenly distribute the gradient over the height of the displacement: If you want the Main Preview window to show the planet correctly make sure to right-click on the Main Preview window and select the custom high-resolution CubeSphere mesh! With the release of 2018.3, Shader Graph introduced a new master node for the HDRP. This post will walk you through our process. Unity Shader Graph Procedural Planet Tutorial. This lets you optimize your shaders using systems like Shader Level of Detail (LOD). Introduction to Shader Graph: Build your shaders with a visual editor. To make the biomes and the transitions from biome to biome more random looking we can use noise and multiply the y-Position by it before sampling the biome gradient. Welcome!!! Instead of sampling a colour gradient we Lerp from texture to texture over the height of the displacement/Length of the vertex Position, blending textures based on displacement height.To control where the textures start and end we can use different black & white gradients. This new master node, called Lit Master, makes many of the advanced shading features found in HDRP accessible in Shader Graph.
