72    <h3>Distance attenuation</h3>
73    <p><B>Distance attenuation</B> can be set when the light type is a <B>Point light</B> or <B>Spotlight</B>. <br /></p>
74    <p>A lookup table can also be used to make settings and/or edits.</p>
75    <p class="hint">If <B>Enable </B>(checkbox) is not selected, be sure to check it when setting <B>Distance attenuation</B>.</p>
76    <img class="manual_image" src="assets/fragmentlight_panel_02.png" alt="Fragment Lighting Category Distance Attenuation"/>
77    <p class="warning">When using a lookup table, you must first create a lookup table set and select the lookup table set to use under <B>General </B>settings.</p>
78    <img class="manual_image" src="assets/fragmentlight_panel_01.png" alt="Fragment lighting Properties panel"/>
79    <p>For details on lookup table sets, click <a href="../../../../tool_panel/lookuptable_set/index.html">Here</a>.</p>
80    <h3>Angular attenuation</h3>
81    <p><B>Angular attenuation</B> can be set when the light type is <B>Spotlight</B>. <br /></p>
82    <p>A lookup table can also be used to make settings and/or edits.</p>
83    <p class="hint">For <B>Angular attenuation</B> as well, you must select <B>Enable </B>(checkbox) located in the <B>Distance attenuation</B> section.</p>
84    <img class="manual_image" src="assets/fragmentlight_panel_03.png" alt="Fragment lighting category angular attenuation"/>
85    <p class="warning">As with <B>Distance attenuation</B>, when using a lookup table, you must first select a lookup table set in the <B>General</B> category.</p>
86    <p>For details on lookup table sets, click <a href="../../../../tool_panel/lookuptable_set/index.html">Here</a>.</p>
87    <h4>Input angle</h4>
88    <p>The input values used in lookup tables are called input angles because angles are used. </p>
89    <p>For details on the types of input angle, click <a href="../../../../../user_guide/material/lookup_tables/index.html#input_angle">here</a>.</p>
90    <h4>Scale</h4>
91    <p> Here, the scale setting applied to lookup table output relates to light intensity. </p>
92    <p>The larger the scale, the stronger the light. The smaller the scale, the weaker the light.</p>
