Where there are multiple sets of light data, there are multiple <CODE><FragmentLightCtr></CODE> tags below the <CODE><Lights></CODE> tag. <CODE><FragmentLightCtr></CODE> contains the following light-related information: 15</p> 16 17<h2>Light Type</h2> 18<p> 19There are three light types, as listed below. The light type is specified by the <CODE>LightKind</CODE> attribute of the <CODE><FragmentLightCtr></CODE> tag. 20</p> 21 22<ul> 23<li>Directional Light</li> 24<p>When <CODE>DirectionalLight</CODE> is specified for the <CODE>LightKind</CODE> attribute, the light type is a directional light.</p> 25 26<li>Point Light</li> 27<p>When <CODE>PointLight</CODE> is specified for the <CODE>LightKind </CODE>attribute, the light type is a point light.</p> 28 29<li>Spot Light</li> 30<p>When <CODE>SpotLight</CODE> is specified for the <CODE>LightKind </CODE>attribute, the light type is a spot light.</p> 31</ul> 32 33<h2>Light SRT Information</h2> 34<p> 35This stores information about the light's position, rotation and scaling. 36</p> 37 38<table> 39<tr><td> 40<pre> 41<NintendoWareIntermediateFile><br> 42 <GraphicsContentCtr><br> 43 <Lights><br> 44 <FragmentLightCtr><br> 45 <Transform><br> 46</pre> 47</td></tr> 48</table> 49 50<h2>Light Color Information</h2> 51<p> 52The four following parameters are stored as the light color information.
