17    <h1>Hemispherical Lights</h1>
18    <!-- InstanceEndEditable --> <!-- InstanceBeginEditable name="本文" -->
19    <p>This page describes the basics of creating and setting hemispherical lights.</p>
20    <h2>Hemispherical Lights</h2>
21    <p>If you tilt the axis of the lighting sphere, the model's vertex colors change depending on the angles between the model's normals and the axis of the lighting sphere.</p>
22    <p class="hint">The top is called the <B>sky color</B>, and the bottom is called the <B>ground color</B>.</p>
23    <h3>Loading Models</h3>
24    <p>On the CreativeStudio menu, select <B>File</B> → <B>Open</B> → <B>Intermediate file</B> to load the model intermediate file.</p>
25    <p>In this example, we describe a spherical model that uses Lambert shading.</p>

27    <p>Reference: <br /> The size and position of the sample sphere being used are given below. <br />Here, Maya is being used as the 3DCG tool. (Defaults are used for all tool settings.)</p>
28    <ul>
29      <li>Radius: 3.5</li>
30      <li>X, Y, Z position: 0 , 3.5 , 0</li>
31    </ul>
32    <h3>Material Panel Settings</h3>
33    <p>You can use the CreativeStudio material <B>Properties</B> panel to configure a material to be lit solely by hemispherical lights.</p>
34    <p>Select a material displayed in the <B>Contents</B> panel to open the material <B>Properties</B> panel.</p>
35    <h4>Changing lighting settings</h4>
36    <p>Under <B>Lighting</B> on the <B>General</B> tab of the material <B>Properties</B> panel, select <B>Enable hemispherical lighting</B>.</p>
37    <img class="manual_image" src="assets/hemisphere_lighting02.png" alt="Rendering settings"/>
38    <h4>Texture Combiner Settings</h4>
39    <p>Configure the settings for combiner 0 on the material panel as follows.</p>
40    <p>For details on texture combiners, click <a href="../../../../../ui_reference/panel/property/material/standard_panel/standard_panel_combiner/index.html#combiner">here</a>.</p>
41    </p>
42    <img class="manual_image" src="assets/hemisphere_lighting03.png" alt="Cube model combiner image"/>
43    <p class="hint">This configures the material to only be lit by vertex lights.<br /> With this configuration, you cannot use the B: Source 1 and C: Source 2 settings.</p>
44    <h3>Creating and Configuring Hemisphere Lights</h3>
45    <p>On the CreativeStudio menu, click <B>Create</B> → <B>Light</B> → <B>Hemispherical light</B> to create a hemispherical light.</p>
46    <a href="assets/hemisphere_lighting04.png" rel="ibox" title="Click the image to enlarge"><img class="ui_thumb" src="assets/hemisphere_lighting04.png" alt="Creating a hemispherical light"/></a>
47    <h4>Opening the Light Panel</h4>
48    <p>Click a light displayed in the <B>Contents</B> panel to open the light <B>Properties</B> panel.</p>
49    <h5>Adjusting the Ground Color</h5>
50    <p>Change the light panel ground color settings to the values below.</p>
51    <img class="manual_image" src="assets/hemisphere_lighting05.png" alt="Changing the ground color"/>
52    <p>These settings produce the following preview.</p>
53    <a href="assets/hemisphere_lighting06.png" rel="ibox" title="Click to enlarge image"><img class="ui_thumb" src="assets/hemisphere_lighting06.png" alt="Preview after changing the ground color"/></a>
54    <h5>Changing the Sky Color Weight</h5>
55    <p>Change the weight of the sky color to adjust the relative strengths of the sky and ground colors.</p>
56    <img class="manual_image" src="assets/hemisphere_lighting07.png" alt="Changing the Sky Color Weight"/>
57    <p>Setting the sky color weight closer to 1 makes the sky color stronger, and setting the weight closer to 0 makes the ground color stronger.</p>
58    <p>In this example, we set the sky color to 1, making the sky color stronger as shown below.</p>
