                            <comment id="58428" author="techzela" created="Tue, 2 Apr 2013 02:19:08 +0200"  >&lt;p&gt;That&apos;s why Its not a direct issue, because code wise its a lighting issue, its because of an underlying issue,&lt;br/&gt;
The same issue as to why half slabs display black. Its because of blocks are treated the same.&lt;br/&gt;
Additional blocks are treated different.&lt;/p&gt;

&lt;p&gt;Bottom line: Minecraft is code is poorly done. But remember this was one of the first things ever coded by the guy!&lt;br/&gt;
If only all of us could do such a great job on our first try! It just needs some refinement and TLC...&lt;/p&gt;</comment>
                            <comment id="58426" author="techzela" created="Tue, 2 Apr 2013 02:13:00 +0200"  >&lt;p&gt;Note: That this is a retention issue. Like Glow-stone holding sunlight.&lt;/p&gt;

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

&lt;p&gt;Torches do not hold retain light.&lt;/p&gt;

&lt;p&gt;Before a block is updated its Sunlight or Lack of Sunlight is retained.&lt;br/&gt;
When the near block is updated so is the Sunlight.&lt;/p&gt;

&lt;p&gt;This is why when a Block is removed the black lighting is also removed.&lt;/p&gt;

&lt;p&gt;Why glowstone? Well simply put blocks are treated different than something like a glass panel, pot, or sign.&lt;br/&gt;
Hope this help in understanding the issue.&lt;/p&gt;</comment>

 Understand that the lighting is per block area. &lt;br/&gt;
The block area is 1 brighter because of its location to the light. &lt;br/&gt;
Its actually closer to the light therefor is brighter.&lt;/p&gt;</comment>

&lt;p&gt;It looks to me like the bug isn&apos;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&apos;re all equally sunlit, is not applied to glass panes &#8212; in the screenshot I&apos;m attaching, see how the sides of the glass blocks are three different slightly-darker-than-white shades and the glass panes are not.&lt;/p&gt;</comment>
