            <title>[MCPE-20515] Stairs have an odd lighting quirk due to their multiple-cuboid model</title>
                <link>https://bugs.mojang.com/browse/MCPE-20515</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;At night or in a dark room, if you look at the back side of stairs when there is a light source behind the stairs, there is a lighting quirk that occurs - most likely due to the multiple cuboids in the stairs model. Note that this issue only seems to occur with smooth lighting enabled.&lt;/p&gt;

&lt;p&gt;This bug was previously mentioned in &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-8054&quot; title=&quot;Texture glitch for stairs &quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-8054&quot;&gt;&lt;del&gt;MCPE-8054&lt;/del&gt;&lt;/a&gt;, but since that ticket had become bloated with a total of 3 technically separate bugs (2 of which had been fixed), the remaining bug (this one) was reported separately and &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-8054&quot; title=&quot;Texture glitch for stairs &quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-8054&quot;&gt;&lt;del&gt;MCPE-8054&lt;/del&gt;&lt;/a&gt; was resolved as fixed.&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;StepstoReproduce%3A&quot;&gt;&lt;/a&gt;Steps to Reproduce:&lt;/h3&gt;
&lt;ol&gt;
	&lt;li&gt;Set your brightness to 0 and enable smooth lighting.&lt;/li&gt;
	&lt;li&gt;Go into a dark room or set the time to night.&lt;/li&gt;
	&lt;li&gt;Place down stairs. (quartz is the best for seeing the bug)&lt;/li&gt;
	&lt;li&gt;Place a torch in front of the stairs. (the side with the steps)&lt;/li&gt;
	&lt;li&gt;View the stairs from the flat back side.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;instead of fixing the lights, they don&apos;t make lights pass through anymore, for java&lt;/p&gt;</comment>
                            <comment id="854295" author="zebulanstanphill@gmail.com" created="Tue, 1 Dec 2020 21:06:06 +0100"  >&lt;p&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=DeeFeeCee&quot; class=&quot;user-hover&quot; rel=&quot;DeeFeeCee&quot;&gt;DeeFeeCee&lt;/a&gt;, I just tested in 1.16.100 and the issue is still there, though it&apos;s worth noting that it only occurs when smooth lighting is enabled (and is most clearly visible when brightness is set to 0). I&apos;ve updated the issue description to mention this.&lt;/p&gt;

&lt;p&gt;1.16.101 appears to be a Switch + mobile-only hotfix with no bugfixes related to lighting, so I&apos;m guessing the bug isn&apos;t actually fixed in that version. If it does still appear to be fixed with smooth lighting enabled and brightness set to 0 (and make sure it&apos;s in a dark room or at night), let me know.&lt;/p&gt;</comment>
