Description

Class for handling Cubemap arrays.

Modern graphics APIs (e.g. D3D10.1 and later, OpenGL 4.0 and later, Metal on macOS, PS4) support "cubemap arrays", which are arrays of same size & format cubemaps. From the shader side, they are treated as a single resource, and sampling them needs an extra coordinate that indicates which array element to sample from.

Typically cubemap arrays are useful for implementing efficient reflection probe, lighting and shadowing systems (all reflection/cookie/shadow cubemaps in a single array).

Cubemap arrays do not have an import pipeline for them, and must be created from code, either at runtime or in editor scripts. Using Graphics.CopyTexture is useful for fast copying of pixel data from regular Cubemap textures into elements of a cubemap array. From editor scripts, a common way of creating serialized cubemap array is to create it, fill with data (either via Graphics.CopyTexture from regular cubemaps, or via SetPixels or SetPixels32) and save it as an asset via AssetDatabase.CreateAsset.

Note that not all platforms and GPUs support cubemap arrays; for example none of the mobile APIs/GPUs currently support them. Use SystemInfo.supportsCubemapArrayTextures to check.

Properties

cubemapCountNumber of cubemaps in the array (Read Only).
formatTexture format (Read Only).

Constructors

CubemapArrayCreate a new cubemap array.

Public Methods

ApplyActually apply all previous SetPixels changes.
GetPixelsRetrieves a copy of the pixel color data for a given mip level of a given face of a given slice. The colors are represented by Color structs.
GetPixels32Retrieves a copy of the pixel color data for a given face of a given slice, at a given mip level. The colors are represented by lower-precision Color32 structs.
SetPixelDataSet pixel values from raw preformatted data.
SetPixelsSet pixel colors for a single array slice/face.
SetPixels32Set pixel colors for a single array slice/face.

Static Properties

allowThreadedTextureCreationAllow Unity internals to perform Texture creation on any thread (rather than the dedicated render thread).
currentTextureMemoryThe amount of memory that all Textures in the scene use.
desiredTextureMemoryThe 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.
GenerateAllMipsCan 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.
nonStreamingTextureCountThe 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.
nonStreamingTextureMemoryThe 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.
streamingMipmapUploadCountHow many times has a Texture been uploaded due to Texture mipmap streaming.
streamingRendererCountNumber of renderers registered with the Texture streaming system.
streamingTextureCountNumber of streaming Textures.
streamingTextureDiscardUnusedMipsThis 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.
streamingTextureForceLoadAllForce streaming Textures to load all mipmap levels.
streamingTextureLoadingCountNumber of streaming Textures with mipmaps currently loading.
streamingTexturePendingLoadCountNumber of streaming Textures with outstanding mipmaps to be loaded.
targetTextureMemoryThe 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.
totalTextureMemoryThe 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.
