![]() Change the name of the Shader to something more descriptive like Shader-ShaderLab. Creating a ShaderĬreate a Shader in the same way as a Material, but selecting Shader in the menu. Change the name of the Material to something more descriptive like Material-ShaderLab. Unity’s surface shaders can compute Phong tessellation automatically using tessphong:VariableName compilation directive. It’s quite an effective way of making low-poly meshes become more smooth. A new material called New Material will appear in the Project View. Phong Tessellation modifies positions of the subdivided faces so that the resulting surface follows the mesh normals a bit. Creating a MaterialĬreate a new Material by clicking Create in the Project View and choosing Material. you should now see a gray sphere in the Preview section of the Inspector View for the material. Make sure the plane does not cover the entire screen so you can see the difference between rendering with a shader and without it. For example, Metal supports tessellation, but not hull or domain stages. tesshw: Hardware tessellation is supported, but not necessarily tessellation (hull/domain) shader stages. randomwrite or uav Random write (UAV) textures are supported. Then select the Align with View option from the menu GameObject. The Layered Lit Tessellation Shader allows you to stack up to four tessellated Materials on the same GameObject in the High Definition Render Pipeline (HDRP). Compute shaders, structured buffers, and atomic operations are supported. Double-click the Main Camera Object from the Hierarchy view and get a Scene View of the plane. Then position the camera so it can show the plane. ![]() ![]() Click on Create > Plane in the menu Hierarchy View, or try out one of the other methods to do this in Unity. The first step in this scene setup is to create a plane. If you are not familiar with Unity’s Scene View, Hierarchy View, Project View and Inspector View, now would be a good time to read the first two sections ( Unity Basics and Building Scenes) of the User Manual. If not, create a new project by choosing File > New Project… from the menu. Configuring a Unity ProjectĪfter starting Unity, you will probably be viewing an empty project. The setup of the plane and the camera is explained, moreover the shaders can work with any geometry without major modifications. The initial examples you are going to use are a plane and a camera pointing at the plane to show the different functionality of the fragment shaders. Finally It appears that the Graphic Emulation Metal in the Unity Editor is not working with Tessellation so use None.This section describes how to setup a basic scene in Unity that you can work with. Amplify shader has some issues that can be addressed by matching closely to the Unity Standard shaders. ![]() So I can confirm that in a build the Unity Standard Tessellation shaders are Working. I have not dived deeper yet to find the exact change I need to make, maybe it's something I am missing in the Shader Editor Properties. I now have my custom built shader from amplify working, but have lost the ability to edit it visually. I also removed the ASE elements (so it won't open in the Amplify Shader Editor) And that worked. So I decided to duplicate my Amplify shader and edit it in Visual Studio to match closer to the unity tessellation naming and convention. But Unity's Standard Tessellation shaders did work when I ran a build. Amplify tessellation materials would not show up. But I still had issues when I went to build to my iPad (2018). ![]() I use Amplify shader and I have to also check Direct X 11 as a target in Amplify shader to see the effect in editor. So in Unity I have to set my Graphic Emulation to none to see the Tessellation in editor. Ive only found examples of tessellation shaders running via surface shaders. I have everything updated to 12.1 iOS, latest xCode. I am using windows to build for Xcode on my mac. ![]()
