Fog of War

Control what players can see on the map using fog of war and line of sight.

How Fog of War Works

Fog of war reveals areas based on:

• PC token positions
• Vision radius (darkvision)
• Active light sources
• Wall obstructions (UVTT maps)

Vision Modes

Fog Mode

• Map is hidden outside PC vision
• Only revealed areas are visible to players
• Creates exploration atmosphere

Token Mode

• Entire map is visible
• Enemy tokens are hidden outside PC vision
• Useful for exploration without hiding geography

Toggle between modes using the LOS switch in the toolbar.

Ambient Light

Set the base lighting level:

Change using the ambient light dropdown.

Reveal Map

The Reveal Map toggle bypasses fog of war:

• Entire map visible to players
• All tokens visible (including hidden)
• Use for area overviews or non-combat scenes

Wall Occlusion

UVTT maps include wall data for accurate line of sight:

• Walls block vision
• Doors can be open or closed
• Creates realistic room-by-room exploration

Standard image maps don’t have wall data - vision is circular.

Tips

• Use darkness for dungeon atmosphere
• Toggle lights for dramatic effect
• Reveal Map for town maps where fog doesn’t make sense
• Switch to Token mode for complex combat
