colors | The array of pixel colours to use. This is a 3D texture 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 . |
Sets the pixel colors of an entire mipmap level.
This method sets pixel data for the texture in CPU memory. Texture.isReadable must be true
, and you must call Apply after SetPixels32
to upload the changed pixels to the GPU.colors
must contain the pixels slice by slice starting at the front of the texture. Each slice must contain the pixels row by row, starting at the bottom left of the texture. The size of the array must be the width × height × depth of the mipmap level.
A single call to SetPixels32
is usually faster than multiple calls to SetPixel, especially for large textures.SetPixels32
might be slower than some other texture methods because it converts the Color32 struct into the format the texture uses. To set pixel data more quickly, use SetPixelData instead.
You can use SetPixel32
with the following texture formats:
Alpha8
ARGB32
ARGB4444
BGRA32
R16
R8
RFloat
RG16
RG32
RGB24
RGB48
RGB565
RGB9e5Float
RGBA32
RGBA4444
RGBA64
RGBAFloat
RGBAHalf
RGFloat
RGHalf
RHalf
For all other formats, SetPixels32
fails. Unity throws an exception when SetPixels32
fails.
