{{Template:ProTip|For advanced users whom want to get rid of the islands right away, CTRL+Left Click one triangle on each navmesh you want to ''keep'' and then press '''"I"'''. This is called '''Inverse Flood Fill''' and selects all navmeshes not currently selected. Once you press '''"I"''' and all of the islands are selected, delete them with '''"R"''' or '''"DELETE"'''.  This is faster than deleting each unwanted island manually, but it's also much easier to accidentally delete useful navmesh - be careful!}}

{{Template:ProTip|As you create and edit more and more navmeshes you will want to begin using [[Navmesh_Cheat Sheet|Navmesh hotkeys]] instead of using the toolbar.

'''G''' toggles Edge Selection On/Off}}

{{Template:WarningBox|Make sure you ''do not'' have Grid Snap on.  You don't need it when navmeshing and will only cause problems if left on.}}

{{Template:ProTip|Navmesh editing uses a separate set of hotkeys than regular Creation Kit editing.  Some hotkeys you may be accustomed to, such as '''"T"''' for top-down viewing, are re-bound to new keys while editing navmesh mode.  You may wish to print and refer to the [[Navmesh Cheat Sheet]] while getting used to this mode.}}

{{Template:InDepth|Notice that two vertices remain green/selected after creating the triangle. This makes it easier to create subsequent triangles. With two vertices selected, all you need to do to create another triangle is '''CTRL+Right-Click'''. A new vertex is created where you click and automatically creates a new triangle.}}

{{Template:ProTip|With this technique, you can create triangles very quickly and cover a lot of ground by simply using CTRL-Right Click.  We fondly call this technique "Walking the Dog".}}

{{Template:WarningBox|You'll be notified upon saving your plugin if you have any errors. Regardless if you get an error or not when saving, you should always run "Check Navmesh".}}

{{Template:ProTip|If you don't want to fix each error by hand, click through each bad triangle with the "Next Warning" button, then choose '''"Yes"''' to delete all of the problem triangles.  This will let you know where to check the navmesh for missing coverage after the deletion.}}

{{Template:InDepth|Cover information isn't just used for ranged combat - it also determines where an AI will tend to go when fleeing from an enemy, for example. So it's a good idea to generate this information, even when it doesn't seem important.<br>

Navmesh can hold more data than just cover - it's also possible to mark triangles as water, preferred, and edges as drop-down ledges. More information can be found [[:Category:Navmesh#Navmesh_Data|here]].<br>

It is also possible to fine-tune cover data, although this level of detail isn't often necessary. To manually adjust cover data, select an edge and press '''"E"'''. This will summon the "''Edge Cover''" dialog.}}
