describe how to remove the influence of parents for child particles generated fro particles set to follow an effect. </p> 14<p>The basic procedure is given below.</p> 15<ul class="sub_page"> 16 <li><a

22<h2>Preparing Effect Files</h2> 23<h3>Confirming the Loading of the File</h3> 24<p>The effect file used in this tutorial is located in the folder given below. </p> 25<p>" SampleData/Effect/Intermediate/ManualResource/Fire_Effect/Fire_Effect.cptl "</p> 26<p>" SampleData/Effect/Intermediate/ManualResource/Star_Effect/Star_Effect.cptl.cptl "</p> 27<h3>Creating a new project</h3> 28<p>On the main menu, select File > New > Project to open a dialog box for creating new projects. </p> 29<p>Without changing the project name, just press OK.</p> 30<h3>Loading the effect <B>Rain</B></h3> 31<p>On the main menu, select File > Open, and load the file Rain_Effect.cptl located in the folder Rain_Effect.</p> 32<p>Rain consists of two particles and two child particles.</p> 33<p>The effect is easier to understand if you put comments such as given below in the comment field for each entry. </p> 34<ul> 35 <li>The rain effect changes to a rain cloud and rain effect</li> 36 <li>The particle Cloud_Particle changes to a rain cloud particle</li> 37 <li>The particle Rain_Particle changes to a rain particle</li> 38</ul> 39<h3>Loading the effect Star</h3> 40<p>On the main menu, select File > Open, and load the file Star_Effect.cptl located in the folder Star_Effect.</p> 41<p>Star_Effect consists of particles and child particles. </p> 42<p>The following are comments for each entry.</p> 43<ul> 44 <li>The effect Star_Effect changes to a moving start effect</li> 45 <li>The particle Star_Particle changes to a star particle</li> 46 <li>The child particle Star_Child_Particle changes to a star child particle</li> 47</ul> 48<a name="SET_FOLLOW"></a> 49<h2>Follow Settings and Effect-based Control</h2> 50<p>Here, we will use the Rain effect.</p> 51<p>You can control particles and the emitters that emit the clouds and rain by moving the effect.</p> 52<h3>Cloud and rain particle follow settings</h3> 53<p>Open <B>Property</B> windows for both Cloud_Particle and Rain_Particle, and set <B>Follow Effect</B> under <B>Emitter</B> to <B>ON</B>.</p> 54<p>This setting allows the Cloud_Particle and Rain_Particle emitters and particles used by the Rain effect to all be controlled together.</p> 55<h3>Viewer confirmation</h3> 56<p>Select the Rain effect and press F5 to transfer data to the Viewer. </p> 57<p>Open the Rain effect <B>Property </B>window, and check the display on <B>Viewer </B>while moving the slider for the <B>Translate X</B> value for <B>Location</B> under <B>Effect</B>.</p> 58<p>The cloud and rain particles will now track the motion of the effect.</p> 59<p class="img"> <img src="images/tutorial_06_02.gif" alt="Follow Settings"> </p> 60<a name="RESET_FOLLOW"></a> 61<h2>Non-follow Settings and Emitter-based Control</h2> 62<p>Particles can be left to remain in place by moving the emitter that emits the cloud and rain particles. </p> 63<h3>Cloud and rain particle non-follow settings</h3> 64<p>Restore the follow settings for Cloud_Particle and Rain_Particle to original status. </p> 65<p>Open <B>Property</B> windows for both Cloud_Particle and Rain_Particle, and set <B>Follow Effect</B> under <B>Emitter</B> to <B>OFF</B>.</p> 66<p>This can reduce the processing load by the amount required to follow the effect.</p> 67<h3>Viewer confirmation</h3> 68<p>Select the Rain effect and press F5 to transfer data to the Viewer. </p> 69<p>Open the Property windows for Cloud_Particle and Rain_Effect, and check the display on Viewer while moving the slider for the Translate X value for Location under Effect.</p> 70<p> The rain cloud and rain particles can be left behind. </p> 71<p class="img"> <img src="images/tutorial_06_03.gif" alt="Leave Behind Setting"> </p> 72<a name="SET_PLACE_WORLD"></a> 73<h2>Child Particle Follow Control</h2> 74<p>Here, we use the Star_Effect effect. </p> 75<p>You can control follow and non-follow using <B>Place in the world coordinate system</B> for child particles. </p> 76<h3>Following child particles</h3> 77<p>Select Star_Effect and press F5 to transfer data to the Viewer. </p> 78<p>Open the <B>Property</B> window for Star_Effect, and check the display on <B>Viewer</B> while moving the slider for the <B>Translate Y</B> value for <B>Location</B> under <B>Effect</B>.</p> 79<p>You can check Star_Particle particles that follow the Star_Effect effect and Star_Child_Particle child particles influenced by them. </p> 80<p class="img"> <img src="images/tutorial_06_04.gif" alt="Child follow"> </p> 81<h3>The <B>Place in the world coordinate system</B> setting</h3> 82<p>Open a <B>Property</B> window for Star_Child_particle and set <B>Place in the world coordinate system</B> under <B>Particle</B> to on. </p> 83<p>This setting causes child particles to no longer be influenced to follow the parent particle that emitted them.</p> 84<h3>Child particle non-follow</h3> 85<p>Select Star_Effect and press F5 to transfer data to the Viewer. </p> 86<p>Open the <B>Property</B> window for Star_Effect, and check the display on <B>Viewer</B> while moving the slider for the <B>Translate Y</B> value for <B>Location</B> under <B>Effect</B>.</p> 87<p>You can check Star_Child_Particle child particles left behind by Star_Particle particles that follow the Star_Effect effect. </p> 88<p class="img"> <img
