Assets. Add the following three properties to the top of the shader. When the distance between the water and the ground is small (shown in green), the color of the water is lighter. This article by Unity explains it in further detail. What does TRANSFORM_TEX do? It might seem unintuitive that TRANSFORM_TEX takes in the texture (a sampler2D) as an argument, but is actually using the scale and offset data of said texture (a float4). Now, if you select the Water4Advanced game object, you will see that you have several properties that you can change. Increasing the foam distance makes the foam around the objects look correct, but is far too strong for the shoreline. Unity Shader Graph – Cartoon Stylized Water with Foam Shader Tutorial. ; Options What color is outputted from the gradient will be controlled by the depth of the objects under the water. Get access to over one million creative assets on Envato Elements. You might have noticed in the code block above the line declaring a sampler2D named _CameraDepthTexture. I'm assuming that you either started by using the current Starting Project or you have finished the previous Unity Terrain tools tutorial. We also pass it through the saturate function—this function clamps the value between 0 and 1, which is the range we need. Initially, you will work with Water (Basic). If we revisit the following line, we can take a look at how this blending works. The transparency parameter doesn’t actually control the shader’s opacity, but rather controls the amount of visibility of the objects rendered underneath the water. Although coloring by depth does give the illusion of transparency, the texture of the sand does not at all show through the water. Services. Send me some feedback about the tutorial in the form below. Next, in your Project tab, open the Standard Assets folder and open Environment again. This is to transform the coordinate from an orthographic to a perspective projection. We now have the view normal of the water's surface and the object behind it. When the dot product is large (near 1), we'll use a lower foam threshold than when it is small (near 0). Download Stylized Water Shader Free Unity. The foam right now looks great near the shoreline, but is barely visible around the edges of the floating objects. In this video, we’ll take a look at how we can use the Shader Graph feature in Universal Render Pipeline, or URP for short, with Unity to create a water shader! To get a clearer view, open this image full-screen in a new tab. Since it's possible that our water could be infinity deep, we add the _DepthMaxDistance property as a cutoff for the gradient—anything deeper than this will no longer change color. Thanks! Team Unityassets4free There are plenty of ways to create a stylised water effect in Unity URP. Services. Note that the, As we move left to right on this graph, further away from the camera, larger distances are represented by smaller values in the depth buffer. We will replicate this as a function in our CGPROGRAM. This will add the WaterBasicDaytime to the scene. By saturating the dot product result, we get our value in the 0...1 range, making it easy to pass into the lerp function, same as we did for interpolating the color of the water. Modfying the color of the foam yields mixed results, with red foam turning pink and black foam light blue. Spring 2020. That looks much better. We want to sample this texture at the same position as the current pixel we're rendering. Cart. Lead discussions. Tags:Stylized Shaders VFX Report As you move a vector away from parallel—towards perpendicular—the dot product result will move from 1 to 0 non-linearly. That way, nearly vertical surfaces (like the rocks) can get foam deeper than very flat objects, like shoreline. Because we want our final output to maintain transparency, we also perform the blend on the alpha channel of the colors. Unity 2018; Amplify Shader Editor (Unity plugin) - if you don't want to spend any money, Unity has introduced its own shadergraph system, but this is still in development. When the vectors are parallel in the same direction and are unit vectors (vectors of length 1), this number is 1. Before moving on, here's a quick explanation of prefabs. Open the Main scene (located at the project root), and open the ToonWater shader (located in the Shaders directory) in your preferred code editor. This script instructs the camera to render the depth texture of the current scene into the above shader variable. Looking for something to help kick start your next project?
