Declarationpublic void
SetPixels(Color[]
colors,
CubemapFace face);
Parameters Parameter Description colors The array of pixel colours to use. This is a 2D image flattened to a 1D array. miplevel The mipmap level to writecolors to. The range is 0 through the texture's Texture.mipmapCount. The default value is 0. face The CubemapFace to write colors to. Description
Sets the pixel colors of an entire mipmap level of a face.
This method sets pixel data for the texture in CPU memory. Texture.isReadable must be true, and you must call Apply after SetPixels to upload the changed pixels to the GPU.
Apply is an expensive operation because it copies all the pixels in the texture even if you've only changed some of the pixels, so change as many pixels as possible before you call it.
colors must contain the pixels row by row, starting at the bottom left of the face texture. The size of the array must be the width à height of the mipmap level.
A single call to SetPixels is usually faster than multiple calls to SetPixel, especially for large textures.
SetPixels might be slower than some other texture methods because it converts the Color struct into the format the texture uses. To set pixel data more quickly, use SetPixelData instead.
You can use SetPixels with the following texture formats:
For all other formats, SetPixels fails. Unity throws an exception when SetPixels fails.
