Brightness in the end[edit]

The table for brightness does not show the brightnesses in the end and I think it should. 01:44, 27 February 2015 (UTC)

There is no sky light in the end, and light giving blocks act exactly the same. KnightMiner t/c 04:22, 27 February 2015 (UTC)
In that case, there should be a separate thing that tells the brightness compared to a light level of 15 in the overworld or the nether. 21:11, 8 March 2015 (UTC)
Based on it acts the same as the overworld, I will add a note stating "Overworld or End", there is no need to add a separate thing when its the same. KnightMiner t/c 21:35, 8 March 2015 (UTC)
I notice that it isn't dark underground in the end, even without torches. 21:53, 8 March 2015 (UTC)
Calculated brightness curves for the three dimensions, during the day with brightness set to "moody". Horizontal axis is block light, vertical is sky light.

The brightness tables in the article seem to be wrong or outdated, and the implication that brightness in the End is the same as in the Overworld is certainly wrong.

We start with the world's light brightness table, from WorldProvider.generateLightBrightnessTable(). Here the Overworld and the End are the same, calculating brightness as (level / 15) / ((1 - level / 15) * 3 + 1) while the Nether (in WorldProviderHell) does (level / 15) / ((1 - level / 15) * 3 + 1) * 0.9 + 0.1. Various further manipulations are done in EntityRenderer.updateLightmap() to determine the final brightness curves as shown in the image to the right, but the bit of real interest is that it tests whether the dimension is the End and if so ignores sky light completely and recalculates block light with a different curve.

Other things of note:

  • A block light level is brighter than a sky light level. This is probably balanced by the fact that block lighting where you can actually see it maxes out at 14 rather than 15.
  • I see code to implement a slight flickering in block light levels. The image to the right uses a "flicker factor" of 0, which should be the average.
  • Block light level 0 in the Nether is closer to the Overworld's block light level 7.
  • Daylight is white, while nightlight is blueish. Block light is orangeish in the middle values.
  • Since the Nether's ambient lighting is basically just making block light brighter thanks to the absence of sky light, it too has an orange tinge. The End's ambient lighting has a cyan tinge.
  • If there were sky light in the End, it wouldn't make things any brighter. You can also see this if you summon lightning somewhere where it can't set fires: it doesn't brighten the world while striking like it does in the Overworld or the Nether.

1.11 Makes darkness absolute?[edit]

It looks to me like as of 1.11, the default "Moody" setting makes darkness a lot darker -- in fact, similar to the effects of the Hardcore Darkness mod. 0 light means, you don't see anything! I wanted to confirm this before adding it to the page, especially as I don't have the new light-response curves, and wouldn't know how to make the graphical image showing the sky/block combination. --MentalMouse42 (talk) 03:44, 26 December 2016 (UTC)

I'm not seeing any difference, switching between 1.11 and 1.10 and 1.9 and 1.8. Are you sure you're on vanilla and not Optifine or something? – Sealbudsman talk/contr 16:26, 26 December 2016 (UTC)
Yup, brand new profile, MC 1.11 not Forge. --MentalMouse42 (talk) 02:24, 27 December 2016 (UTC)
Here's what I see (click for bigger): File:SealbudsmanLightLevels.gif <-- this is under a stone platform at night; you can see the moonlight in the background, and the total darkness in the foreground, with a torch so you can see the difference – Sealbudsman talk/contr 05:41, 28 December 2016 (UTC)
Weird -- up through 1.10.2, I was seeing much more visibility in the total darkness, which also matches what I'd been seeing in people's videos and such, say when they were mining. For that matter, it matches the current text on the page proper here: "Full darkness is about 5% brightness" In total darkness, it was difficult to see the difference between, say, stone and ore, but I could definitely see where the blocks themselves were, which I can't anymore in the game (or your GIF). (And in fact, the "Hardcore Darkness" mod was specifically developed to make that not happen.) And yes, I played on the default "Moody", I was always about leaving things as default unless I had a particular reason to change them. --MentalMouse42 (talk) 11:40, 28 December 2016 (UTC)
ETA: Combining this thread with discussions elsewhere, I have now reached the point of "if a third person tells you you're a duck...". I think that an IRL visit to an eye doctor is in my near future. :-( . -MentalMouse42 (talk) 12:19, 28 December 2016 (UTC)
Might depend on the screen and its settings?
Also my picture has debug text, so the white F3 text almost completely washes out everything else (did you notice the andesite and snow block behind the blazing white text, for instance?)
Also this is grass, which is a bit darker than stone under dim light.
Also there's a significant difference between cave darkness and moonlit darkness.
This was also taken with original lighting, not with smooth lighting. I think smooth lighting creates even more shadows?
Just some ideas. I hope it's not your eyes :) . – Sealbudsman talk/contr 14:10, 28 December 2016 (UTC)
The thing is, I myself can't see a difference between the different MC versions in your GIF. and other people have also been telling me "what change? I haven't seen any change!" What I see in your GIF is still a blatant difference from what I remember, but much closer to what I'm seeing now. Again, there's that saying: If you go out one day, and the first person you talk to tells you "hey, you're a duck!", you laugh at them. If the second person you meet also says "you're a duck", quit laughing. If a third person then tells you "you're a duck"... check for feathers.
Then too, I did just turn 50, and I have been having more problems reading fine print lately. I had been assuming that it was just the usual focusing issues that come with age, but a proper ophthalmologist can check my light/dark sensitivity, and test for gross physical issues . --MentalMouse42 (talk) 15:57, 28 December 2016 (UTC)
I wouldn't rule out a simple confabulation of memory, either; the mind can be a slippery thing. Maybe you weren't always on Moody, for instance? Maybe you always played on original lighting, and recently you switched to smooth?
As for eyesight and memories of playing on Moody lighting -- for comparison, I'm only thirty-two, (I think that means my eyes are ... okay?) and to my memory, I've mostly played in Moody as well, except that one thing I remember is that I never play Hardcore in Moody, I always play Hardcore in 50%, because the underground on Moody has always been just too pitch-black for those kind of risks.
who knows! – Sealbudsman talk/contr 16:34, 28 December 2016 (UTC)

Lighting in the Nether and the Lighting curves[edit]

It says, "In the Nether, sky lighting doesn't play a role since there is no source of sky light ". If this is true, then the nether section of the "lighting curves" picture should be similar to that of the Night or End (except the tint). Is there anything more to consider?
