r/FoundryVTT

Hi there! I'm new to Foundry but I've been using it for a few days now. I've been using DroidCartographer's modular maps for most of my map building, and they're working amazing -- But for this level I imported a JPG map with no walls or lights set up, and set them all up myself. When I went to add lights, there's this issue with the light over the center of the room. When I select the light, it shows me this odd boundary that shows up but I'm unable to narrow down the source. Did some digging into the problem myself, but I failed to find anything relating to this issue.

Far as I can tell nothing else got uploaded when I set the JPG as the background, and the scale of the map is set correctly to line up with the tiles.

If anyone can offer some advice, that'd be greatly appreciated.

Thank you!

Content Name: Death Effect Reminder

Content Type: Module

System: System-agnostic (dnd5e and Pirate Borg first-class)

Description: When a hostile or neutral NPC dies during combat, the module scans its actions, features, and traits for death-triggered rules buried in stat-block text - explosions, revival saves, lingering hazards, loot triggers, and similar effects GMs forget mid-fight.

It posts a chat card listing likely candidates with saving-throw buttons (when the active system supports them) and action buttons so the table can resolve the effect without the GM digging through the sheet.

Output is advisory, not automation - the GM still decides what actually fires. Works in dnd5e and Pirate Borg with best-effort support for other systems. Foundry v13 to v14.

Early access through the r2Plays Patreon at First Mate tier. Install via the FutureHax Module Catalog or the Jolly Rogenerator foundry page.

donjon.bin.sh's 5e dungeon generator is great, but once you generate and export the JSON you're locked to the map and have no way of editing it or re-viewing it. So I had AI reverse-engineered the export format and built a tool that re-renders everything locally and offline, and then lets you edit the result.

What it does:

• Reads donjon's exported JSON and re-renders the GM map, player map, a clickable HTML doc, and TSV/CSV — all offline.

• Maps are drawn procedurally with Pillow: rooms, corridors, polygon/circle rooms, stairs, and the full door set (arch / door / locked / trapped / secret / portcullis). Door and stair glyphs are generated as pure integer pixel art at the target cell size; no resampling, so lines stay crisp at any scale.

• A desktop GUI turns it into an editor: paint corridors (with auto-door placement), create / delete / reshape / resize rooms, resize the canvas, mirror rooms, and edit room contents/monsters/treasure/doors.

The procedural-gen-relevant bits were the fun part: donjon packs everything into a 2D array of integer bitmasks (block / room / corridor / wall / aperture / room-ID / door-type / stair / label-char bits), with a symmetric padding offset between the cells array and the map coordinate space. I documented the whole encoding in the repo since I couldn't find it written down anywhere.

Repo: https://github.com/DawnGuardian/Donjon-Regen

Release: https://github.com/DawnGuardian/Donjon-Regen/releases/tag/v1.0.0

Happy to answer anything about the bitmask format or the rendering pipeline. (Full disclosure: the code was written with AI assistance but the tool's output is fully deterministic, no AI-generated content.)

Hi everyone! I just released my first major Foundry VTT module: Ravnica Navigator.

To make campaign preparation easier and give both DMs and players a more intuitive experience, I built a scene navigation tool designed specifically for Ravnica campaigns. GMs can place marker pins on the Tenth District map, bind them to key locations or adventure scenes, and click to view thumbnails or jump directly to the destination – all with smooth transitions.

And it's completely free, including a bundled compendium pack with over 125 Ravnica maps. If you use another VTT and only want the free map assets from the included compendium, you can export them directly from the modules/ravnica-navigator/map folder.

Feel free to ask any questions – happy to help.

if you played the old DOOM games I'm sure you remember the character picture "degrading" with your hit points. I wanted that in foundry as well, so i made this module. We used it for quite some time and after some polish its now released on foundryvtt. Its completely free and open source. You can check out the Github here:
https://github.com/aronjanosch/dynamic-tokens

https://foundryvtt.com/packages/dynamic-tokens

For transparency: Yes I used AI to code this, no I don't want your money and yes I understand the code, I'm an IT professional in cyber security by trade.

It's simple to setup everything lives in the appearance tab of the token settings and you can preview the changes there. You can also randomize images for thresholds and have status effect overrides. On my table its mainly used by players.

Btw...

I also recently added foundry support for my world building app i build for myself and I'm using all the time for my table. I am looking for folks testing the app. https://github.com/aronjanosch/chronicle-keeper

Hi! I need some help with Foundry VTT v13.

I'm using Foundry to display the game on a TV for my players. I control an invisible token that moves around the map to reveal areas through Fog of War.

The problem is that when the token enters a room, only the area within its line of sight is revealed. My maps have pillars, corners, furniture, and other obstacles that block vision, so parts of the room remain covered by Fog of War until I move the token around.

What I'd like instead is this:

• As soon as the token enters a room, the entire room is permanently revealed in Fog Exploration.
• Other rooms should remain hidden until the token enters them.
• I don't want to manually move the token around every corner just to uncover the whole room.

Is there a built-in way to do this in Foundry VTT v13, or is there a module or macro that can reveal an entire region/room when a token enters it?

Any suggestions would be greatly appreciated!

Content Name: Selective Sight

Content Type: Module

System: System-agnostic

Description: Show different tiles, drawings, tokens, and map notes to different players — all in the same active scene, with shared mouse positions and pings intact.

Each player sees whatever the GM has tagged for them. One player finds a wardrobe that doesn't exist on anyone else's map. Another sees a rune no one else can read. A ghost that only the haunted character can perceive. Nothing in the scene data changes; visibility is suppressed client-side so the rest of the shared canvas works normally.

GMs configure visibility from a right-click context menu or HUD button on any tile, drawing, token, or note. A "preview as player" toolbar mode lets the GM verify exactly what each player sees before the session starts.

Early access through the r2Plays Patreon at First Mate tier. Foundry v13 to v14, any system.

Content Name: Ocean — Water & Sea Simulator

Content Type: Module

System: System Agnostic

Hey folks,

Really happy to finally share this one with you. I've been working on Ocean for a long time, and honestly, it's a really special module to me

Ocean turns any Foundry Region into living water, and any token into a ship. Draw a region, add the ocean water behavior, and that area becomes an ocean, a lake, a river, or a still pool down in a dungeon. The surface moves on its own and never loop

You can adjust almost everything about the water: color, flow speed and direction, lighting mood, how big the waves get, foam, reflections and more. The settings you'll reach for most are gathered in a "favorites" panel, so you can get a good-looking sea in seconds and then go as deep as you like, saving your own presets along the way

Turn a token into a ship and it really sits in the water: when a swell rolls through, the bow lifts and the hull rocks. Ships leave a wake as they sail, and a token wading across a lake sends ripples spreading outward, ring after ring. Scene light has a real position and color, so switching between a clear day, a golden sunset or a moonlit night shifts the whole mood of the sea in real time

Ocean is currently in early access for the "The Architect" tier on Patreon, and will open to everyone once the early access period wraps up. The 3D ship hulls come from the companion scenic3d module, installed alongside ocean.

This one's special to me. I started making it because my own campaign is about to reach its ocean exploration arc. It was also incredibly complicated to pull off, honestly the second most complex module I've built so far

 I really hope you enjoy it.

Have fun out there, and let's ride the waves!:D
