With the new changes done to the texture import settings we have lost the possiblity of forcing any texture to an especific format (like rgba 16 bit) to all platforms at the same time. The “Format” dropbox in the texture setting under “Default” is always greyed out. We can change the “Max size” and “compression” but not the “Format”. To change the format you have to go to each platform an enable “Override” which is a same, because now you have to rememebr to change all platforms each time you want to change anything. In previous Unity versions it was working perfectly.
In the docs says that it’s this way, but IMO i think is a step back.
