How To Animate A Fish Swimming With Shaders

Animate Fish Swimming With Shaders We are going to make swimming animation by using only shader code. By the time we are done, it's going to look like this. Pretty Damn Cool... You will probably need the fish model used in this tutorial, that can be found HERE . Can use your own model but the shader code might have to be modified accordingly because of the orientation of the model that you might be using ( issues with whether the X axis & Z axis is flipped ). The shader used way out performs a similar scene with skeletal animations applied on the fish models. On a previous benchmark I did comparing the shader animation with the skeletal animation there was a difference of 28 FPS( on average ) with 50 fish. The shader we are going to make is really powerful and flexible and don't think that it's limited to making fishes swim😀. Y-Z Axis So this mesh oriented like this when imported into unity and this is important to understand because this means th...

Access Reflection Probe Data For Custom Shaders

The Unity shader documentation regarding reflection probes is pretty minimal and not at all comprehensive. This short tutorial is intended to bring reflection probe functionalities to the forefront your future shader writing endevors which is a fancy way of saying "Look at this cool stuff and go and use it somewhere" 😏 Here we will try just the bare minimum of making a shader that reflects the cubemap data from reflection probe and displays it on the object. These reflection probes are basically objects that store a complete image of the environment surrounding it into a cubemap which then can be read by shaders to create various effects. More information on how reflection probes work in Unity can be found here : Using Reflection Probes In Unity I am not going over how to set up Reflection Probes here only how to access them inside our custom shaders. So this is what we will be making: A sphere with a reflection probe affecting it The reflection probe takes...

Pixelation Shader - Unity Shader

Pixelation Shader This is the correct way (one of many) of showing pixelation as a post-processing effect. This effect will work in any aspect ratio without any pixel size scaling issues as well as it is very minimal in terms of coding it up. pixelate image effect in action In order to get this to work 2 components have to be set up: 1) The pixelation image effect 2) The script - which will be attached to the camera So let's get started by creating a new image effect shader. We will take a look at our Shaderlab properties : _MainTex("Texture", 2D) = "white" {} That's it, Everything else will be private and not shown in the editor. Now we will see what are defined along with the _MainTex but are private. sampler2D _MainTex; int _PixelDensity; float2 _AspectRatioMultiplier; We will pass _PixelDensity & _AspectRatioMultiplier values from the script. As this is an image effect there is no need to play around with the vertex shader....
