colors | The array of pixel colours to use. This is a 2D image flattened to a 1D array. |
miplevel | The mipmap level to write colors to. The range is 0 through the texture's Texture.mipmapCount. The default value is 0 . |
face | The CubemapFace to write colors to. |
arrayElement | The array slice to write colors to. |
Sets the pixel colors of an entire mipmap level of a face of a slice.
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 × height of the mipmap level.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.
