This series focuses on Unity Shaders and Effects Cookbook (thanks to the author of the book), plus a bit of personal understanding or outreach. Here are all the illustrations of this book. Here is the code and resources required for this book (you can also download it from the website, of course). ========================================== Split Line ========================================== In the previous article, we learned how to use the prope

Deferred Lighting delay IlluminationTime- lapse illumination is the rendering path with the highest fidelity illumination and shading. If you have a lot of real-time lighting, it's best to use delayed lighting. It requires a level of hardware support that is only available in Unity Pro and not supported on mobile devic

Note that unity has used our new half Lambert illumination model (which is used to highlight the brightness of the backlight) and added a new sample color. The left side is the previous result, and the right side is the result. Explanation When writing a shader, we can use the # include preprocessing command to inc

Render path and color space1:unity shadow effect can be set by setting the rendering path and color space;2: Render Path: Light to the surface of the object, when the object is colored, the color of the light when there are so several ways of shading, the way to calculate coloringForward: shading according to the corresponding influence of light, each light source color once, multiple light sources will be colored multiple times;Advantages: Fast, low

object can control whether a single object has a shadow, provided the light is shaded. second, baking lightmappingreal-time lighting and shading have a great impact on game performance when the scene contains a large number of objects. Using baking techniques, you can pre-render light effects to map and then simulate shadows on objects to improve performance. Step 1:1. The game object and the ground are set to static;2. Select Window-lightmapping-bak

Art students think Unity lighting is not enough to bake the beautiful, need to repair in PS, but do not know each object corresponding to the light map in which area, how the UV distribution, so asked to write a tool display, so there is the following:Open the scene automatically read the current baked light map, in the scene to select objects in the form of a green box to display the light map UV distribut

The fourth chapter reflects the end of the reflection, then continue to study the fifth-light model.We are already familiar with the illumination model, before the various diffuse and specular highlights have been customized to the Illumination model function. I thought this chapter would be about the light model function that I said earlier, but it's not.After reading the first section, the feeling is that it's like teaching me how to use the baked pictures. That means how to use a static pictu
