Still a concern in 1.8.2 pre 2

Comment by Daniel Chehade [ 03/Sep/14 ]

Confirmed in 1.8 (Release) too!

Comment by [Mod] Sonicwave [ 27/Aug/14 ]

Confirmed in 1.8-pre2.

Comment by Anton Kudin [ 11/Jul/14 ]

Thought they fixed it for a brief moment in the snapshots. But it's back again (in 28b for sure)

Comment by Andrew Thomas [ 10/Jul/14 ]

Confirmed for 14w28b

Comment by eleazzaar [ 18/Oct/13 ]

This issue is still present in snapshot 13w42a for both regular and stained glass

Comment by [Mod] CubeTheThird [ 26/Sep/13 ]

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Its nota glitch in the blocks the glitch its that the pane dont get darkness from the shadow and its more lighter than the block, I think

Comment by Nathan Gorzelanczyk [ 02/Apr/13 ]

That's why Its not a direct issue, because code wise its a lighting issue, its because of an underlying issue,
The same issue as to why half slabs display black. Its because of blocks are treated the same.
Additional blocks are treated different.

Bottom line: Minecraft is code is poorly done. But remember this was one of the first things ever coded by the guy!
If only all of us could do such a great job on our first try! It just needs some refinement and TLC...

Comment by Nathan Gorzelanczyk [ 02/Apr/13 ]

Note: That this is a retention issue. Like Glow-stone holding sunlight.

1) Recreate it by making a dark room BLl0 SL0 RL0
2) Place Glows-tone, Note light, BLl8 SL0 RL8 (0 Sunlight)
3) Place Remove a block allowing sunlight, Note light, BLl8 SL8 RL8 (8 Sunlight)
4) Place block back allowing no sunlight, Note sunlight does not change, BLl8 SL8 RL8 (8 Sunlight)

Torches do not hold retain light.

Before a block is updated its Sunlight or Lack of Sunlight is retained.
When the near block is updated so is the Sunlight.

This is why when a Block is removed the black lighting is also removed.

Why glowstone? Well simply put blocks are treated different than something like a glass panel, pot, or sign.
Hope this help in understanding the issue.

Confirmed for 1.5.1

Comment by Calvin Lee [ 02/Apr/13 ]

In at least 5 snapshots(pictures) the light comes from above, below, or both. in mine craft and real life the thickness is the same verticly and that means that no extra light should come through (see attached snapshot)

Comment by Nathan Gorzelanczyk [ 02/Apr/13 ]

Also note: In real life thinner glass lets more light through.

Comment by Nathan Gorzelanczyk [ 01/Apr/13 ]

This is not a bug.
Understand that the lighting is per block area.
The block area is 1 brighter because of its location to the light.
Its actually closer to the light therefor is brighter.

Comment by Calvin Lee [ 03/Mar/13 ]

Can confirm in 13w09c

Comment by Alex de la Cruz [ 02/Feb/13 ]

I think its the other way around, the glass pane is brighter than the glass block

Comment by Kevin Reid [ 29/Jan/13 ]

(Confirming for 13w04a.)

It looks to me like the bug isn't related to darkness (block/sky lighting) but rather that the mild directional lighting which is applied to all normal blocks, making different faces different shades even if they're all equally sunlit, is not applied to glass panes — in the screenshot I'm attaching, see how the sides of the glass blocks are three different slightly-darker-than-white shades and the glass panes are not.

Comment by MisterSanderson [ 27/Jan/13 ]

But the normal glass block is a block, and the glass pane is a fraction of a block, like flowerpots, stairs, etc.

Comment by Kumasasa [ 27/Jan/13 ]

Is it ? Both glass block and glas pane are transparent and solid.

Comment by MisterSanderson [ 27/Jan/13 ]

This seems to be the same problem of MC-2399.

Comment by Kadwyn [ 25/Jan/13 ]

Glass and glass panes get their (front) texture from the same file. So surely one being darker than the other is a bug?

Comment by Huskehn [ 24/Jan/13 ]

I agree that this is a bug. Certainly not game-breaking, but annoying.

Comment by Ender [ 11/Dec/12 ]

I don't think that this is game breaking though...

Comment by Adam C [ 21/Nov/12 ]

Added another screenshot which I thought illustrated the problem better than any of the screenshots you uploaded. This is definitely a bug

Comment by MisterSanderson [ 15/Nov/12 ]

The glass block is darker because there is much more glass blocking the light, this is not a bug.

Comment by Mustek [ 14/Nov/12 ]

Reopening this issue.

Comment by christian bro [ 10/Nov/12 ]

I think this is a bug,too.

Comment by Pablo González Rubio [ 10/Nov/12 ]

ok!

Comment by Mustek [ 10/Nov/12 ]

No, this is a personal preference.

Comment by Pablo González Rubio [ 10/Nov/12 ]

this is a bug....

Surely that is the fault of paralytic skeletons
