RNK™ Master View

Advanced lighting, vision limitation, and fog of war controls for Foundry VTT.

Supports Foundry VTT V11, V12, and V13

Features

Master View

When no tokens are controlled, GMs can see the entire scene with adjustable brightness.

Global Light Configuration

Fully customize the global/ambient light source with all standard light options:

• Color and intensity
• Luminosity, saturation, contrast, shadows
• Animation type, speed, and intensity
• Darkness threshold (when global light activates)

Illumination Colors

Set custom daylight and darkness colors for each scene:

• Daylight Color: Illumination at darkness level 0
• Darkness Color: Illumination at darkness level 1

Vision Limitation

Restrict how far tokens can see:

• Set maximum sight range per scene
• Configure limits for each detection mode
• Apply limits within light sources or drawings
• Stack limitations from multiple sources

Lighting Drawings

Control lighting within drawing boundaries:

• Enable any drawing to define a lighting region
• Inherit settings from other drawings or the scene
• Auto-fit drawings to wall structures
• Override global light, colors, and vision limits

Fog of War Reveal

Reveal fog of war for all users without affecting saved exploration progress.

Light Priority

Control how light sources interact:

• Higher priority lights override lower priority for vision effects
• Darkness sources can suppress normal lights

// Toggle debug mode
RNKVision.debug = true;


// Toggle Master View Hub
RNKVision.toggleGMHub();


// Toggle GM Vision
RNKVision.toggleGMVision();


// Get region at a point
const region = RNKVision.lightingSystem.getRegionAt({x: 1000, y: 1000}, 0);


// Check if fog is revealed
const revealed = region?.fogRevealed;
