<h1>Visual vertices (UDMF)</h1>
</div>
<div id="contents">
<p>Visual vertices allow you to edit vertical vertex offsets in Visual mode.<br/>
You can select and edit them just like Things (except you can't move them horizontally).<br/>
You can use the &quot;<strong>Delete</strong>&quot; action (usually bound to Delete key) to clear z-offsets of selected vertices.<br/>
You can toggle the Visual vertices display from the <a href="../general/rendering_toolbar.html">Rendering toolbar</a> or the &quot;<strong>Toggle Visual Vertices</strong>&quot; action.<br/>
Visual vertices with height offset (e.g. with some values in &quot;zceiling&quot; or &quot;zfloor&quot; UDMF fields) are colored using the &quot;Info Line&quot; color. Visual vertices without offsets are colored using the &quot;Vertex&quot; color. You can change these colors in Preferences -&gt; Appearance.</p>
<p> <strong>Technical note &#8470;1:</strong> Visual vertices work only if a map is in UDMF map format.<br/>
<strong>Technical note &#8470;2:</strong> Visual vertices work only for triangular sectors.</p>
<p>It took approx. 30 seconds to create this wonderous terrain:<br />

<p>You can create much more elaborate terrains using <a href="../classic_modes/mode_importterrain.html"><strong>Terrain Importer</strong></a>.</p>
