プラグインとして新規グローバルシェーダーを作成する | Unreal Engine 4.27 ドキュメンテーション

Unreal Engine 4 (UE4) プラグインシステムを使うと、エンジン全体の再コンパイルおよび配布をせずに誰でも幅広い新機能を追加することができます。以下の How - To で、Lens Distortion グローバルシェーダープラグインを再生しして、ブループリントで操作可能なグローバルシェーダーの実装方法を実演します。

クリックしてフルサイズで表示。

Engine\Plugins\Compositing\LensDistortion にある既存の Lens Distortion プラグインを Foo と呼ばれる新規プラグインに再度作成して、このワークフローを実行する方法を実演します。

このクイックスタートでは、グローバルシェーダーをプラグインとして作成および使用する方法を体験します。

1 - コード設定

Unreal Engine (UE4) 用のプラグインの新規作成を始める前に、Visual Studio がインストールされていることを確認してください。この操作ガイドでは、プラグインのコードをコンパイルして実行可能にする必要があるので、Visual Studio が必要になります。インストール方法が分からない場合は UE4 用に Visual Studio を設定するを参照してください。

まず、新しい Games プロジェクトを作成し、Blank (空の) テンプレートを選択します。 [Maximum Quality] と [No Starter Content] を必ず有効にしてください。
プロジェクトが作成されたら Visual Studio を開きます。ShadersInPlugins プロジェクトを右クリックして [Build] オプションを選択し、プロジェクトをコンパイルします。
プロジェクトのコンパイルが完了したら、Visual Studio の F5 キーを押して UE4 エディタで ShadersInPlugins プロジェクトを起動します。
UE4 エディタのロード処理が完了したら、[Edit] > [Plugins] から Plugins マネージャを開いて [Plugin] ウィンドウの右下にある [New Plugin] オプションをクリックして新規プラグイン作成ウインドウを開きます。

クリックしてフルサイズで表示。

[New Plugin] ウィンドウから [Blank] プラグインを選択し、[Name] 欄に 「Foo」 と入力し、すべての設定をデフォルトにします。すべての設定をデフォルトにしたら、[Create Plugin (プラグインを作成)] ボタンを押して、最初にプラグインが必要とするすべてのコンテンツを作成します。

クリックしてフルサイズで表示。

これが完了したら、UE4 と Visual Studio を閉じます。次にプロジェクトフォルダ内に作成された [Plugins] > 「Foo plugin」フォルダを開きます。
「Foo plugin」フォルダ内に 「Shaders」 という名前の新規フォルダを追加し、その中に 「Private」 という名前の新規フォルダを作成します。

クリックしてフルサイズで表示。

「Private」フォルダの中にテキストファイルを新規作成し 「MyShader.USF」 と名前を付けたら、以下の HLSL コードをこのファイルにコピーペーストして、完了したらファイルを閉じます。

ファイルの拡張子を .USF に必ず変更してください。そうしないと、これがシェーダーファイルであることを UE4 が認識しません。

次に Plugins\Foo\Source\Foo を開き 「Classes」 という名前の新規フォルダを作成し、「LensDistortionAPI.h」 と 「LensDistortionBlueprintLibrary.h」 ファイルを Engine\Plugins\Compositing\LensDistortion から新規作成したこのフォルダへコピーします。

コピーするファイルは Engine\Plugins\Compositing\LensDistortion にあります。

* Classes - Create New Folder

「Private」フォルダを開き「LensDistortionBlueprintLibrary.cpp」と「LensDistortionRendering.cpp」ファイルの両方をこの「Private」フォルダにコピーします。
- Private - Existing Folder
  - Copy - LensDistortionBlueprintLibrary.cpp

UE4 と Visual Studio を両方とも閉じて、今度は「projects .U」ファイルを探します。見つかったら、右クリックして [Generate Visual Studio project files] オプションを選択します。
Visual Studio ソリューションを再度開き、[Foo] > [Classes] から「LensDistortionAPI.h」ファイルを開きます。このファイル内で FLensDistortionCameraModel を FFooCameraModel に置き換えます。

プロジェクトの Visual Studio ソリューションファイルを再起動し、CRTL + 5 を押してプロジェクトを再コンパイルします。これが完了したら、F5 を押して UE4 エディタを起動します。
UE4 エディタのロード処理が完了したら、[Edit] > [Plugins] から Plugins マネージャーを開きます。
Plugins マネージャーを一番下までスクロールすると [Project] セクションがあります。そこに Plugin があります。

プラグが有効になっていない場合、名前の横にあるチェックマークボックスをクリックすると UE4 エディタが再起動します。

すべてそろっていることを確認するためには、Level ブループリントを開いてイベントグラフを右クリックし、検索ボックスに「Foo」と入力します。これが完了すると、Foo Camera カテゴリに追加されたすべてのアイテムを見ることができます。

クリックしてフルサイズで表示。

最終結果

これで Lense Distortion UE4 プラグインの新バージョンの再生成とコンパイルが無事完了しました。次のステップでは、この新しいグローバルシェーダーをブループリントから呼び出して、レンダーターゲットをどのように変形するのか見てみましょう。

4 - ブループリントの設定

プラグインの動作が検証されたので、このステップではブループリントを使ってグローバルシェーダーを呼び出す方法を説明します。

機能の仕方を確認するために コンテンツブラウザ を右クリックして、親クラスとして名前のついた アクタ のある新規 Blueprint クラス を作成します。
次に、「RT_00」 という名前の レンダーターゲット および MAT_RT という名前のマテリアルを新規作成します。
MAT_RT マテリアルを開いて、RT_00 レンダーターゲットをマテリアルグラフに追加し、 Main Material ノードの Base Color 入力に接続し、[Apply] と [Save] ボタンを押します。

クリックしてフルサイズで表示。

次に、DrawUVDisToRenderTarget ブループリントを開き、以下の変数とノードをイベントグラフに作成 / 追加します。

変数	デフォルト値
K1	1.0
K2	1.0
inc	1.0

ノード	デフォルト値
W	N/A
S	N/A
Event Tick	N/A
Draw UVDisplacement to Render Target	FOV、Aspect Ratio、Overscan Factor に1 を入力します。
Make FooCameraModel	N/A
Clear Render Target 2D	N/A

Draw UVDisplacement to Render Target が提供されたレンダーターゲットをラップするか簡単に実演するには、Draw UVDisplacement to Render Target ノードの K1 入力と K2 入力に入力した値をボタンの押下で増加 / 減少できるようにブループリントを設定する必要があります。以下の画像に合わせてイベントグラフのノードを設定すれば完成です。

ブループリントコードをブループリントに直接コピー＆ペーストすることができます。

レンダーターゲットを必ず Output Render Target に入力してください。何も表示されなくなります。

必要なブループリントロジックを設定したら、必ずブループリントを コンパイル および保存して、コンテンツブラウザ から レベル にブループリントをドラッグします。完了したら、ブループリントを選択し、[Input] の [Auto Receive Input] を [Disabled] から [Player 0] へ変更します。

クリックしてフルサイズで表示。

次にフロアを選択し CTRL + W を押して複製し X 軸で -90 度 回転させます。マテリアル MAT_RT をそこにドラッグすれば Draw UVDisplacement to Render Target の効果を確認することができます。

クリックしてフルサイズで表示。

すべてを設定したら、[Play] ボタンを押して、[W] キーと [S] キーを押して Draw UVDisplacement to Render Target ノードに入力されたレンダーターゲットを以下の動画のようにワープします。

最終結果

レンダーターゲット内のコンテンツをブループリントから変形して、面白い形状に自由に作成できるようになりました。次は、新しいプラグインを作成、または既存のプラグインを編集してどんな種類の画像とエフェクトを作成することができるのか見てみましょう。
