| data | The array of data to use. |
| mipLevel | The mipmap level to write to. The range is 0 through the texture's Texture.mipmapCount. The default value is 0. |
| face | The CubemapFace to write to. |
| sourceDataStartIndex | The index in the source array to start copying from. The default value is 0. |
| element | The array slice to write to. |
Sets the raw data of an entire mipmap level of a face directly in CPU memory.
This method sets pixel data for the texture in CPU memory. Texture.isReadable must be true, and you must call Apply after SetPixelData to upload the changed pixels to the GPU.SetPixelData is useful if you want to load compressed or other non-color texture format data into a texture.
The size of the data array must be the width × height of the mipmap level of the face, and the data layout must match the texture format, otherwise SetPixelData fails. You can use byte for T if you don't want to define a custom struct to match the texture format.
Unity throws an exception when SetPixelData fails.
