Represents a shader keyword declared in a shader source file.
Shader keywords determine which shader variants Unity uses. You can use a LocalKeyword to enable, disable, or check the state state of a local shader keyword. For information on working with local shader keywords and global shader keywords and how they interact, see Using shader keywords with C# scripts.
When you declare a shader keyword in the source file for a Shader or ComputeShader, Unity represents the keyword with a LocalKeyword and stores it in a LocalKeywordSpace.
For a Shader:
To set the state of a local shader keyword, use Material.SetKeyword, Material.EnableKeyword, or Material.DisableKeyword.
To check the state of a local shader keyword, use Material.IsKeywordEnabled or Material.enabledKeywords.
To access the LocalKeywordSpace, use Material.shader to access the Shader that the material uses, and then use Shader.keywordSpace.
For a ComputeShader:
To set the state of a local shader keyword, use ComputeShader.SetKeyword, ComputeShader.EnableKeyword, or ComputeShader.DisableKeyword.
To check the state of a local shader keyword, use ComputeShader.IsKeywordEnabled or ComputeShader.enabledKeywords.
To access the LocalKeywordSpace, use ComputeShader.keywordSpace.
In addition to this, you can also enable or disable a local or global keyword with a CommandBuffer. To do this, use CommandBuffer.SetKeyword, CommandBuffer.EnableKeyword, or CommandBuffer.DisableKeyword.
Note: A LocalKeyword is specific to a single Shader or ComputeShader instance. You cannot use it with other Shader or ComputeShader instances, even if they declare keywords with the same name.
