レンダーテクスチャはレンダリングを行なうことができるテクスチャです。
They can be used to implement image based rendering effects, dynamic shadows,
projectors, reflections or surveillance cameras.
One typical usage of render textures is setting them as the "target texture" property
of a Camera (Camera.targetTexture), this will make a camera render into a texture
instead of rendering to the screen.
Keep in mind that render texture contents can become "lost" on certain events, like loading a new level, system going to a screensaver mode, in and out of fullscreen and so on.
When that happens, your existing render textures will become "not yet created" again,
you can check for that with IsCreated function.
As with other "native engine object" types, it is important to pay attention to the lifetime of
any render textures and release them when you are finished using them with the Release function,
as they will not be garbage collected like normal managed types.
A render texture only has a data representation on the GPU and you need to use Texture2D.ReadPixels to transfer its contents to CPU memory.
The initial contents of a newly created render texture are undefined. On some platforms/API's the contents will default to black but users should not depend on this.

| active | 現在アクティブなレンダーテクスチャ |
| antiAliasing | レンダーテクスチャのアンチエイリアスレベル |
| autoGenerateMips | Mipmap levels are generated automatically when this flag is set. |
| bindTextureMS | If true and antiAliasing is greater than 1, the render texture will not be resolved by default. Use this if the render texture needs to be bound as a multisampled texture in a shader. |
| colorBuffer | RenderTexture のカラーバッファ（読み取り専用） |
| depth | The precision of the render texture's depth buffer in bits (0, 16, 24 and 32 are supported). |
| depthBuffer | RenderTexture の深度/ステンシルバッファ（読み取り専用） |
| depthStencilFormat | The format of the depth/stencil buffer. |
| descriptor | This struct contains all the information required to create a RenderTexture. It can be copied, cached, and reused to easily create RenderTextures that all share the same properties. |
| dimension | レンダーテクスチャの次元 (形式) |
| enableRandomWrite | Shader Model 5.0 レベルのシェーダーでこのレンダーテクスチャにランダムアクセス書き込みを有効にします。 |
| graphicsFormat | The color format of the render texture. You can set the color format to None to achieve depth-only rendering. |
| height | ピクセル単位のテクスチャの高さ |
| memorylessMode | The render texture memoryless mode property. |
| sRGB | Does this render texture use sRGB read/write conversions? (Read Only). |
| stencilFormat | The format of the stencil data that you can encapsulate within a RenderTexture.Specifying this property creates a stencil element for the RenderTexture and sets its format. This allows for stencil data to be bound as a Texture to all shader types for the platforms that support it. This property does not specify the format of the stencil buffer, which is constrained by the depth buffer format specified in RenderTexture.depth.Currently, most platforms only support R8_UInt (DirectX11, DirectX12), while PS4 also supports R8_UNorm. |
| useDynamicScale | Is the render texture marked to be scaled by the Dynamic Resolution system. |
| useMipMap | Render texture has mipmaps when this flag is set. |
| volumeDepth | Volume extent of a 3D render texture or number of slices of array texture. |
| vrUsage | If this RenderTexture is a VR eye texture used in stereoscopic rendering, this property decides what special rendering occurs, if any. |
| width | ピクセル単位のテクスチャの幅 |
| RenderTexture | 新規の RenderTexture オブジェクトを作成します |
| ConvertToEquirect | Converts the render texture to equirectangular format (both stereoscopic or monoscopic equirect). The left eye will occupy the top half and the right eye will occupy the bottom. The monoscopic version will occupy the whole texture. Texture dimension must be of type TextureDimension.Cube. |
| Create | 実際に RenderTexture オブジェクトを作成します |
| DiscardContents | Hint the GPU driver that the contents of the RenderTexture will not be used. |
| GenerateMips | Generate mipmap levels of a render texture. |

| ReleaseTemporary | GetTemporary 関数で割り当てられた一時的なテクスチャを解放します |
| SupportsStencil | RenderTexture にステンシルバッファがあるかどうか |
| allowThreadedTextureCreation | Allow Unity internals to perform Texture creation on any thread (rather than the dedicated render thread). |
| currentTextureMemory | The amount of memory that all Textures in the scene use. |
| desiredTextureMemory | The total size of the Textures, in bytes, that Unity loads if there were no other constraints. Before Unity loads any Textures, it applies the memory budget which reduces the loaded Texture resolution if the Texture sizes exceed its value. The `desiredTextureMemory` value takes into account the mipmap levels that Unity has requested or that you have set manually. For example, if Unity does not load a Texture at full resolution because it is far away or its requested mipmap level is greater than 0, Unity reduces the `desiredTextureMemory` value to match the total memory needed. The `desiredTextureMemory` value can be greater than the `targetTextureMemory` value. |
| GenerateAllMips | Can be used with Texture constructors that take a mip count to indicate that all mips should be generated. The value of this field is -1. |
| nonStreamingTextureCount | The number of non-streaming Textures in the scene. This includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| nonStreamingTextureMemory | The amount of memory Unity allocates for non-streaming Textures in the scene. This only includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| streamingMipmapUploadCount | How many times has a Texture been uploaded due to Texture mipmap streaming. |
| streamingRendererCount | Number of renderers registered with the Texture streaming system. |
| streamingTextureCount | Number of streaming Textures. |
| streamingTextureDiscardUnusedMips | This property forces the streaming Texture system to discard all unused mipmaps instead of caching them until the Texture memory budget is exceeded. This is useful when you profile or write tests to keep a predictable set of Textures in memory. |
| streamingTextureForceLoadAll | Force streaming Textures to load all mipmap levels. |
| streamingTextureLoadingCount | Number of streaming Textures with mipmaps currently loading. |
| streamingTexturePendingLoadCount | Number of streaming Textures with outstanding mipmaps to be loaded. |
| targetTextureMemory | The total amount of Texture memory that Unity allocates to the Textures in the scene after it applies the memory budget and finishes loading Textures. `targetTextureMemory`also takes mipmap streaming settings into account. This value only includes instances of Texture2D and CubeMap Textures. This value does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| totalTextureMemory | The total amount of Texture memory that Unity would use if it loads all Textures at mipmap level 0. This is a theoretical value that does not take into account any input from the streaming system or any other input, for example when you set the`Texture2D.requestedMipmapLevel` manually. To see a Texture memory value that takes inputs into account, use `desiredTextureMemory`. `totalTextureMemory` only includes instances of Texture2D and CubeMap Textures. This value does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
