&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[Category:Object Modifiers]]&lt;br /&gt;
{{#indexentry:double_illuminate, object modifier}}&lt;br /&gt;
{{#indexentry:object modifier, double_illuminate}}&lt;br /&gt;
&amp;lt;p&amp;gt;Syntax:&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
OBJECT {&lt;br /&gt;
  [OBJECT_ITEMS...]&lt;br /&gt;
  double_illuminate&lt;br /&gt;
  }&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;p&amp;gt;A surface has two sides; usually, only the side facing the light source is illuminated,&lt;br /&gt;
the other side remains in shadow. When &amp;lt;code&amp;gt;double_illuminate&amp;lt;/code&amp;gt; is used,&lt;br /&gt;
the other side is also illuminated.&lt;br /&gt;
&amp;lt;br&amp;gt;This is useful for simulating effects like translucency (as in a lamp shade, sheet of paper, etc).&amp;lt;/p&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;p class=&amp;quot;Note&amp;quot;&amp;gt;&amp;lt;strong&amp;gt;Note:&amp;lt;/strong&amp;gt; Using &amp;lt;code&amp;gt;double_illuminate&amp;lt;/code&amp;gt; only illuminates both sides of the same&lt;br /&gt;
surface, so on a sphere, for example, you will not see the effect unless the&lt;br /&gt;
sphere is either partially transparent, or if the camera is inside and the light source&lt;br /&gt;
outside of the sphere (or vise versa).&amp;lt;/p&amp;gt;&lt;/div&gt;</summary>
