content: 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)

content: Solder mask opacity setting?Right click on board -> Options -> Board Layers and Colors -> solder mask check-boxes and opacity sliders in 'Colors and Visibility' section

Changing scenes did not help also.Quote from: voltsandjolts on March 24, 2017, 09:37:11 pmNo, it is enabled, and 0.0106mm thick (default value)I did all of those in the first place, but it is something else...

content: Hm, you are right, somehow i have no top and bottom solder mask, only on TH pins, but how could i done this ?But I have Top and Bottom Paste. So how the hell i could disable top and bottom solde rmask on every pad and every track ?Basically i have a layer, but it is nearly empty, only multilayer show up on this layer

content: I have it on gerbers, but i don't see it in altium, or in 3D, somehing is horibly wrong here.and if i select top solder layer, and make square, it does not show upSo i think it is something to do with Altium itself

content: Found a problem !When i was defying board outline, i simply selected pcb outline that i made in keep out layer, but in the middle of pcb i found tiny zero size and length dot in keep out layer.It messed up all of this, because Altium was thinking that was my board:DAfter deleting and redefining board, it started working again.
