ShaderGUI

Description

Abstract class to derive from for defining custom GUI for shader properties and for extending the material preview.

Derive from this class for controlling how shader properties should be presented. For a shader to use this custom GUI use the 'CustomEditor' property in the shader. Note that CustomEditor can also be used for classes deriving from MaterialEditor (search for: Custom Material Editors). Note: Only the ShaderGUI approach works with Substance materials this is therefore the recommended approach to custom gui for shaders. See ShaderGUI.OnGUI, ShaderGUI.OnMaterialPreviewGUI, ShaderGUI.OnMaterialPreviewSettingsGUI.

          Shader "example" {
    // properties and subshaders here...
