Passes use tags to tell how and when they expect to be rendered to the rendering engine.
Tags { "TagName1" = "Value1" "TagName2" = "Value2" }
Specifies TagName1 to have Value1, TagName2 to have Value2. You can have as many tags as you like.
Tags are basically key-value pairs. Inside a Pass tags are used to control which role this pass has in the lighting pipeline (ambient, vertex lit, pixel lit etc.) and some other options. Note that the following tags recognized by Unity must be inside Pass section and not inside SubShader!
LightMode tag defines Pass’ role in the lighting pipeline. See render pipeline for details. These tags are rarely used manually; most often shaders that need to interact with lighting are written as Surface Shaders and then all those details are taken care of.
Possible values for LightMode tag are:
A pass can indicate flags that change how rendering pipeline passes data to it. This is done by using PassFlags tag, with a value that is space-separated flag names. Currently the flags supported are:
A pass can indicate that it should only be rendered when some external conditions are met. This is done by using RequireOptions tag, whose value is a string of space separated options. Currently the options supported by Unity are:
SubShaders can be given Tags as well, see SubShader Tags.
