プルリク : 使い方や説明はプルリクのドキュメント参照

URPについての話題。いずれはURPで使えるようになるハズ。

やり方

メニューからシェーダーテンプレを作成

https://gyazo.com/53f41eb4add193c633ba2cf35369daa7

マテリアルを作ってシェーダーを紐づける

https://gyazo.com/271dc50127b485f0bf949dff3fad32f9

シーンに空のゲームオブジェクトを作ってCustomPassVolumeをアタッチする。

CustomPassにFullScreen Passを追加し、マテリアルを設定する。

シェーダーのFullScreenPassにエフェクトを描く。
