While Shapes are built into jME3, you typically create models in external 3D Mesh Editors.</p></div></div></div>
<div class="sect1"><h2 id="using-models-and-scenes-with-jme3">Using Models and Scenes with jME3</h2><div class="sectionbody"><div class="paragraph"><p>To use 3D models in a jME3 application:</p></div>
<div class="olist arabic"><ol class="arabic"><li><p>Export the 3D model in Ogre XML or Wavefront OBJ format.

<div class="olist arabic"><ol class="arabic"><li><p>(For the release build:) Use the jMonkeyEngine SDK to convert models to .j3o format. You don&#8217;t need this step as long you still develop and test the aplication within the jMonkeyEngine SDK.</p></li></ol></div></div></div>

<div class="paragraph"><p><strong>Tip:</strong> Learn how to create <a href="http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics">UV textures</a> for more complex models, it looks more professional.</p></div>
<div class="paragraph"><p>3D model editors are third-party products, so please consult their documentation for instructions how to use them. Here is an example workflow for Blender users:</p></div>
<div class="ulist"><ul><li><p><a href="../../jme3/external/blender.html">Creating jME3 compatible 3D models in Blender</a></p></li></ul></div>
<div class="paragraph"><p>To export your models as Ogre XML meshes with materials:</p></div>
<div class="olist arabic"><ol class="arabic"><li><p>Open the menu File &gt; Export &gt; OgreXML Exporter to open the exporter dialog.</p></li><li><p>In the Export Materials field: Give the material the same name as the model. For example, the model <code>something.mesh.xml</code> goes with <code>something.material</code>, plus (optionally) <code>something.skeleton.xml</code>, and some JPG files.</p></li><li><p>In the Export Meshes field: Select a target subdirectory of your <code>assets/Models/</code> directory. E.g. <code>assets/Models/something/</code>.</p></li><li><p>Activate the following exporter settings:</p><div class="ulist"><ul><li><p>Copy Textures: YES</p></li><li><p>Rendering Materials: YES</p></li><li><p>Flip Axis: YES</p></li><li><p>Require Materials: YES</p></li><li><p>Skeleton name follows mesh: YES</p></li></ul></div></li><li><p>Click export.</p></li></ol></div>
<div class="paragraph"><p>You can now use the <a href="../../sdk.html">jMonkeyEngine SDK</a> to <a href="../../sdk/model_loader_and_viewer.html">load and view models</a>.
