파라미터

shader Shader that is being compiled.
snippet Details about the specific shader code being compiled.
data List of variants to be compiled for the specific shader code.

설명

Implement this interface to receive a callback before a shader snippet is compiled.

Check global keywords by constructing a ShaderKeyword instance with the name of the keyword. To check local keywords, use an additional parameter to specify the shader that is using the local keyword.

using UnityEngine.Rendering;

class MyCustomBuildProcessor : IPreprocessShaders { ShaderKeyword m_GlobalKeywordBlue;

public MyCustomBuildProcessor() { m_GlobalKeywordBlue = new ShaderKeyword("_BLUE"); }

public int callbackOrder { get { return 0; } }

public void OnProcessShader(Shader shader, ShaderSnippetData snippet, IList<ShaderCompilerData> data) { ShaderKeyword localKeywordRed = new ShaderKeyword(shader, "_RED"); for (int i = data.Count - 1; i >= 0; --i) { if (!data[i].shaderKeywordSet.IsEnabled(m_GlobalKeywordBlue)) continue; if (!data[i].shaderKeywordSet.IsEnabled(localKeywordRed)) continue;

data.RemoveAt(i); } } }
