Grid
There are a number of different grid options to choose from, including size of the grid, how diagonal distance is measured, the type of grid (square, horizontal hex and vertical hex), (D&D 5e/4e, 3.5/Pathfinder, Euclidean, Manhattan, Hex Grid), whether or not to display labels in the cells (hex grids only) and the color and opacity of the grid. Read more about the Ruler and measurements here.
To enable or disable the grid, simply select the Enabled checkbox. If it's checked, the grid is on, unchecked and the grid is completely off.
Note: disabling the grid will also disable any grid snapping effects, since there's nothing for the objects to snap to.
The grid can also be made smaller or larger by adjusting the grid cell size. For example, if I entered 0.5 into the Cell Width (or Cell Height, for Hex (H) grids), the canvas will draw lines twice as often as by default, making each cell 35 pixels across. Likewise, a size of 2 would double the size of each grid cell. You can enter a number as either a multiplier or in pixels. The Page Settings dialog box automatically converts between cell size and pixels.
Just like the background color, you can also select what color you'd like your grid lines to be. By clicking on the color selection box, you'll be presented with a palette where you can either select a color, or enter a custom hex code.
If you'd like to make your grid lines darker or lighter, you can adjust the opacity using the grid opacity slider. This slider will make the grid more, or less transparent, so you can make it fade into the background, or boldly stand out. Simply slide it to the left to make the lines more transparent, or to the right to make them more opaque. If you slide the bar all the way to the left, your lines will become invisible. This is handy if you still want the snap to grid feature, but don't want to see the lines.
GM Opacity
The fog appears as a solid black area to players, but for the GM it's a semi-transparent layer. If you'd like to adjust how dark the fog appears to you (handy for dark maps where it's hard to tell where it is) use the "GM Opacity" slider to adjust how transparent or opaque it appears. Simply slide the slider to the left to make the fog lighter, or to the right to make it darker. If the slider is all the way to the left, the fog will be completely invisible, and if it's all the way right, it will be completely solid.
Play on Load
Choose a Jukebox track or Playlist which will automatically play when you move the players to the page. Note that this only takes effect when a GM moves the Player Ribbon to the page, not for the "split the party" feature (since the Jukebox is global, not player-specific).
Archive Page
You can archive any page to save for use in the future, either in your current game or use the Transmogrifier to move your favorite pages to use in a new game, if you have a Pro/Plus account.
Archived Pages will appear at the far right end of the Pages Menu, from there, they can be restored at any time.
Archiving can be helpful if you have a large number of pages. Move the Players Ribbon to the next page, and then archive the page you moved from.
Delete Page
Clicking this button will permanently delete the current page from the Page Toolbar. Note: You will not be able to delete the page if the Player Ribbon is currently placed upon it or if it's the page that is currently being viewed on the tabletop.
Dynamic Lighting
If you'd like to use the Dynamic Lighting feature, you must first enable it for the page. To do so, select the "Enabled" checkbox. You can use Fog of War In combination with Dynamic Lighting, but one is not dependent on the other to function.
Enforce Line of Sight will allow you to set specific line of sight parameters for tokens. Restrict Movement prevents tokens with vision from passing through vision obstructing obstacles. Global Illumination allows tokens with vision to see everything so long as there are not vision obstructing obstacles blocking their way.
For more information on Line of Sight and Dynamic Lighting, check out the Token Features and Dynamic Lighting help guides.
Legacy Lighting Tab
Fog of War
If you'd like to use the Fog of War feature, you must first enable it for the page. To do so, select the "Enabled" checkbox. This will turn it on for the page, and cover the entire map in fog.
For more information on using Fog of War, including how to reveal areas, consult the Fog of War help guide.
