Custom Render Textures are an extension to Render Textures, enabling you to render directly to the Texture using a Shader.
Custom Render Textures are an extension to Render Textures allowing you easily to update the texture with a Shader and then use it in a regular Material. This is useful for implementing all kinds of complex simulations, for instance: water caustics, ripple simulations for rain effects, or splatting liquids against a wall. Also provided is a scripting and Shader framework to help with more complicated configurations like partial or multi-pass updates, and varying update frequency.
| cubemapFaceMask | Bitfield that allows to enable or disable update on each of the cubemap faces. Order from least significant bit is +X, -X, +Y, -Y, +Z, -Z. |
| doubleBuffered | If true, the Custom Render Texture is double buffered so that you can access it during its own update. otherwise the Custom Render Texture will be not be double buffered. |
| initializationColor | Color with which the Custom Render Texture is initialized. This parameter will be ignored if an initializationMaterial is set. |
| initializationMaterial | Material with which the Custom Render Texture is initialized. Initialization texture and color are ignored if this parameter is set. |
| initializationMode | Specify how the texture should be initialized. |
| initializationSource | Specify if the texture should be initialized with a Texture and a Color or a Material. |
| initializationTexture | Texture with which the Custom Render Texture is initialized (multiplied by the initialization color). This parameter will be ignored if an initializationMaterial is set. |
| material | Material with which the content of the Custom Render Texture is updated. |
| shaderPass | Shader Pass used to update the Custom Render Texture. |
| updateMode | Specify how the texture should be updated. |
| updatePeriod | Period in seconds at which real-time textures are updated (0.0 will update every frame). |
| updateZoneSpace | Space in which the update zones are expressed (Normalized or Pixel space). |
| wrapUpdateZones | If true, Update zones will wrap around the border of the Custom Render Texture. Otherwise, Update zones will be clamped at the border of the Custom Render Texture. |

| GetUpdateZones | Returns the list of Update Zones. |
| Initialize | Triggers an initialization of the Custom Render Texture. |
| SetUpdateZones | Setup the list of Update Zones for the Custom Render Texture. |
| Update | Triggers the update of the Custom Render Texture. |
| active | Currently active render texture. |
| 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. It 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. It does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |

| autoGenerateMips | Mipmap levels are generated automatically when this flag is set. |

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. |
