80    <h3>Distance attenuation</h3>
81    <p>Distance attenuation can be set when the light type is <B>Point light</B> or <B>Spotlight</B>.</p>
82    <p>A lookup table can also be used to make settings and/or edits.</p>

84    <p class="new_hint"><B>Note:</B> The <B>Enable</B> checkbox is cleared by default, so be sure to mark this checkbox when setting Distance attenuation.</p>
85    <p class="hint_warn">Caution:<br /> If you are using a lookup table, you must first create a lookup table set and select that lookup table set in the <B>General</B> category. For details on lookup table sets, click <a href="../../tool_panel/lookuptable_set/index.html">Here</a>.</p>
86    <!-- <img src="assets/fragmentlight_panel_01.png" alt="フラグメントライトパネル"/> -->
87    <h3>Angular attenuation</h3>
88    <p><B>Angular attenuation</B> can be set when the light type is <B>Spotlight</B>. <br /></p>
89    <p>A lookup table can also be used to make settings and/or edits.</p>

91    <p class="new_hint"><B>Note:</B> You need to mark the <B>Enable </B> checkbox in the <B>Distance attenuation</B> category when using Angular attenuation.</p>
92    <p class="hint_warn">Caution:<br /> As with <B>Distance attenuation</B>, when using a lookup table you must select which lookup table set to use in the <B>General</B> category. For details on lookup table sets, click <a href="../../tool_panel/lookuptable_set/index.html">Here</a>.</p>
93    <h4>Input angle</h4>
94    <p>The input values used in lookup tables are called input angles because angles are used.</p>
95    <p>For details on the types of input angle, click <a href="../../../user_guide/material/lookup_tables/index.html#input_angle">here</a>.</p>
96    <h4>Scale</h4>
97    <p> Here, the scale setting applied to lookup table output relates to light intensity.</p>
98    <p>The larger the scale, the stronger the light. The smaller the scale, the weaker the light.</p>
