| updateMipmaps | When set to true, mipmap levels are recalculated. |
| makeNoLongerReadable | Whether to discard the copy of pixel data in CPU-addressable memory after this operation. |
Actually apply all previous SetPixels changes.
If updateMipmaps is true, the mipmap levels are recalculated as well, using
the base level as a source. Usually you want to use true in all cases except when
you've modified the mip levels yourself using SetPixels.
If makeNoLongerReadable is true, Unity will free the memory used to store the CPU-addressable copy of the pixel data after uploading it to the GPU. isReadable becomes false. By default makeNoLongerReadable is set to false.
Apply is a potentially expensive operation, so you'll want to change as many pixels
as possible between Apply calls.
Alternatively, if you don't need to access the pixels on the CPU, you could use Graphics.CopyTexture
for fast GPU-side texture data copies. Note that calling Apply may undo the results of previous calls to Graphics.CopyTexture.
