Hello, i guess i pressed something or Altium is just buggy, but for some reason i can't get solder mask to show up. I clearly have it in layers, but just can't see it.
Did try to press Shift+S, but that does not help, also opacity settings are correct in Layer manager.
Any idea what i did, and how to fix this ? It is not a big problem, but still, want to see complete board
( It is same on 17, and 16 versions, all legal)
