<h2>Setting lower/upper textures:</h2>
|
|
If you are going to connect sectors with different ceiling and/or floor heights, you'll generally want to set upper and/or lower textures. To do this, set upper or lower textures to linedefs, which will be used to define the shape of the bridge. <br>Let's say we want to make a stairway out of these lines:
|
|
<table border="0" cellspacing="3" cellpadding="3">
|
|
<tr>
|
|
<td><b>2D-view:</b></td>
|
|
<td><b>3D-view:</b></td>
|
|
</tr>
|
|
<tr>
|
|
<td valign="top"><img src="bridge_tex1.jpg" /></td>
|
|
<td><img src="bridge_tex1_3d.jpg" /></td>
|
|
</tr>
|
|
</table>
|
|
<br>
|
|
If you bridge these linedefs right now, you'll have lots of unset textures:
|
|
<br>
|
|
<img src="bridge_tex2_3d.jpg" />
|
|
<br><br>
|
|
Instead of setting them all by hand, set the upper and lower textures of those linedefs, which will be used to create this shape (you need to set only one linedef of the pair):
|
|
<br>
|
|
<img src="bridge_tex3.jpg" />
|
|
<br><br>
|
|
If you bridge linedefs now, all upper/lower textures will be set:
|
|
<br>
|
|
<img src="bridge_tex4_3d.jpg" />
|
