シェーダーを交換してカメラをレンダリングします。
詳細は Rendering with Replaced Shaders を参照してください
これはカメラをレンダリングします。カメラのクリアフラグ、ターゲットテクスチャ、他すべての設定を使用します。
The camera will not send OnPreCull, OnPreRender or
OnPostRender to attached scripts. Image filters will not be rendered either.
This is used for special effects, e.g. rendering screenspace normal buffer of the whole scene,
heat vision and so on. To make use of this feature, usually you create a camera and disable it.
Then call RenderWithShader on it.
You are not able to call the Render function from a camera that is currently rendering. If you wish to
do this create a copy of the camera, and make it match the original one using CopyFrom.
