<li>Nodes are the only GameObject to add bridges, railings, signs and similar items. In other words: To add any non-road item you must do so from a Node.</li>
<li>To add nodes, you must have a road selected. Ctrl-left-click to add a node to the end of the road. Shift-left-click to insert a node anywhere along the spline.</li>
<li>Creating a custom extrusion and edge objects is performed by clicking the "Create a custom extrusion object" and "Create a custom edge object" in a Node's inspector window.</li>

<div class="b">Typically auto-split will be the best choice for performance and other reasons.</div>
<div>Choosing split options will split the road/shoulder up into pieces mirroring the road segments between nodes.</div>
<div>Splitting makes mesh collider bound calculations more efficient and fast. Splitting also allows for more detailed and flexible road texturing options such as passing sections, other different road lines per section, road debris and more.</div>
</td></tr>
</table><table cellpadding="0" cellspacing="0" style="margin:0;">
<tr><td class="tocTCcD">
<div class="b">Which splitting option to choose?</div>
<div class="i">Recommended option: auto-split enabled for roads and shoulders.</div>
<div>Choose no splitting if you desire a single material set for this entire road and your game experiences no collision processing slowdowns from one large mesh collider. This option will create less game objects than automatic and manual splitting.</div>
<div>Choose automatic road and shoulder splitting if you desire multiple materials (such as yellow double lines for certain sections and white dotted for others) for this road and or your game experiences collision processing slowdowns from one large mesh collider.</div>
<div>Choose manual road and shoulder splitting if you desire the same as automatic splitting and desire more freedom over the process. This option will result in less GameObjects and larger mesh colliders when compared to automatic splitting.</div>
<div class="b">Manual splitting information:</div>
<div>Choosing manual splitting will force the user to select individual nodes to cut instead of the cuts being performed automatically. This option is recommended if bigger mesh colliders do not cause a slowdown in performance, as it lowers the overall GameObject count.</div>
<div>Manual splitting will not split up the mesh colliders like automatic cuts, so the colliders may get large & complex and cost more CPU to process collisions. If this option is chosen, please verify your game's collision processing speed and if you run into long collision processing times split more road sections.</div>
<div class="b">Example usages of manual splitting:</div>
<div><span class="i">Example hill:</span> Goal is to have double yellow no passing lines on a two lane road but only while the road is near or on the hill.
Pick nodes on either sides of the hill and mark both as road cut. Everything between these two nodes will be its own section
allowing you to apply double yellow no passing lines for just the hill.</div>
<div><span class="i">Example mountains:</span> In the mountains, the road is curvy and the grade is high.
There's a flat straight spot that you want to allow passing in, by marking the road with white dotted passing lines.
At the beginning of the flat straight section, mark the node as road cut. Now at the end of the flat straight section, mark this node as road cut.
This will create a road section between the two nodes, allowing you to apply white dotted passing lines for just the flat straight section.
