The [[Entity atmosphere|atmosphere entity]] essentially adds a ‘sky’ to the map. Its location in the world doesn’t matter. Add an [[Entity atmosphere|atmosphere entity]] and give it a key pair of {{keyname|atmospheredecl}}{{keyvalue|area22_01}}. This is a nice bright, clear day. In order for game components to behave correctly later on, we need to define an outside area in our map. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[[Image:Small outsideportal box.jpg|thumb|left|&lt;br /&gt;
This tells the game which area is outside and which is inside. Inside being the room we just made, and outside being the rest of the map.&lt;br /&gt;

# Like the caulk hull, by using 6 brushes, create a small room from &amp;lt;tt&amp;gt;[[Common Textures#common/caulk|textures/common/caulk]]&amp;lt;/tt&amp;gt; underneath the terrain. &lt;br /&gt;
# Texture one of the brushes with &amp;lt;tt&amp;gt;[[Common Textures#common/nodraw|textures/common/nodraw]]&amp;lt;/tt&amp;gt;, and nudge the brush inwards so the outer face is flush with the adjacent four sides. &lt;br /&gt;
