Custom Render Textures are an extension to Render Textures that allow you to render directly to the Texture using a Shader.
Custom Render Textures are an extension to Render Textures that allow you to update a 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 | The bit field that you can use to enable or disable update on each of the cubemap faces. The bit order from least to most significant bit is as follows: +X, -X, +Y, -Y, +Z, -Z. |
| doubleBuffered | When this parameter is set to true, Unity double-buffers the Custom Render Texture so that you can access it during its own update. |
| initializationColor | The color that Unity uses to initialize a Custom Render Texture. Unity ignores this parameter if an initializationMaterial is set. |
| initializationMaterial | The Material that Unity uses to initialize a Custom Render Texture. Initialization texture and color are ignored if you have set this parameter. |
| initializationMode | Determine how Unity initializes a texture. |
| initializationSource | Determine if Unity initializes the Custom Render Texture with a Texture and a Color or a Material. |
| initializationTexture | The Texture that Unity uses to initialize a Custom Render Texture, multiplied by the initialization color. Unity ignores this parameter if an initializationMaterial is set. |
| material | The Material that Unity uses to initialize the content of a Custom Render Texture. |
| shaderPass | The Shader Pass Unity uses to update the Custom Render Texture. |
| updateMode | Determine how Unity updates the Custom Render Texture. |
| updatePeriod | The period in seconds that Unity updates real-time Custom Render Textures. A value of 0.0 means Unity updates real-time Custom Render Textures every frame. |
| updateZoneSpace | The space in which Unity expresses update zones. You can set this to Normalized or Pixel space. |
| wrapUpdateZones | When this parameter is set to true, Unity wraps Update zones around the border of the Custom Render Texture. Otherwise, Unity clamps Update zones at the border of the Custom Render Texture. |
| CustomRenderTexture | 创建一个新的自定义渲染纹理。 |
| ClearUpdateZones | 清除所有更新区域。 |
| EnsureDoubleBufferConsistency | Updates the internal Render Texture that a Custom Render Texture uses for double buffering, so that it matches the size and format of the Custom Render Texture. |
| GetDoubleBufferRenderTexture | Gets the Render Texture that this Custom Render Texture uses for double buffering. |
| GetUpdateZones | 返回更新区域列表。 |
| Initialize | Initializes the Custom Render Texture at the start of the next frame. Unity calls /Initialise()/ before /CustomRenderTexture.Update/. |
| SetUpdateZones | 为自定义渲染纹理设置更新区域列表。 |
| Update | Triggers an update of the Custom Render Texture. |
| active | 当前处于活动状态的渲染纹理。 |
| 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. |
