Worldbuilding Editor

Intuitive, Fast, Stunning

Build 3D Earth-scale worlds in real-time from your browser

Achieve godlike control over your setting’s geography, cosmology, and weather. You can edit your world’s lore and physical characteristics from the same place, inspect and edit the details of locations, and move around your world in six degrees of freedom - from high in orbit to the ground level - as you shape its features with centimeter precision. With Radian, you have a dedicated “Google Earth” for your creations without the need for downloaded software or complicated map-making workflows.

Mix and Match Visual Layers
For Map Types and Targeted Edits

Rich Information at Your Fingertips

Dedicated Layers for Environmental and Cultural Details

Leverage Radian’s layer based editing to change specific aspects like elevation and precipitation, define named regions, or draw cultural boundaries. Each layer persists throughout your world’s history and can be combined to create dynamic situations or contribute to your game’s stories.

Build it Once, Use it Forever

Maps as a Snapshot of Dynamic Worlds with Perfect Continuity

Build a library of maps by simply drag-selecting portions of your world and populating them with items and culture. Print them to the table or export them to your VTT of choice as player hand-outs or encounter maps. Trade out generic maps for one-to-one representations of places unique to your setting that automatically reflect the state of your world at that point in time with zero additional effort.

Content Management

Publish and Use Content

Build or use packages for your games in a community sharing model

Organize all your setting’s details into packages for re-use across campaigns, or include packages from other gamemasters in your setting for faster creation. Utilize others’ house rules, community made utilities, and deep compendiums of characters, items, places or lore to drastically reduce prep time while delivering a superior quality of life for players and a bottomless sense of scale.

Manage Wikis and Compendiums

Curate Content in an interactive Format for fast retrieval and player access

As a gamemaster, keep vast bodies of knowledge organized by campaign/setting with ease. Use a zettelkasten system to track and quickly retrieve NPCs, events, or items. Allow your players to view aspects of your world, allowing them to jump through richly linked articles, visualize connections, and recall moments they may have forgotten.

Virtual Tabletop

Power to the Tinkerers

Free-Form Rules Engine for Automation and Extension of Any Game

Tired of consulting charts? need to speed up play-times? want to change a game mechanic or create house rules? Mold any system to your expectations or build your own system entirely to craft the game experience you want to deliver. The sky is the limit. Reduce complex turn structures or actions and abilities into buttons on a player hot-bar with zero coding knowledge required, and maintain the ability as a gamemaster to supersede any of your rules in service of “The Rule of Cool”.

Jump In and Get Playing

Limitless Gaming Opportunities with Unbeatable Atmosphere

Browse for games online or gain free access with an existing party code from your gamemaster. Play in a browser-based VTT with 3D rendered encounter assets, intelligent audio and music orchestration, and fully customizable interfaces that complete the aesthetic of any campaign - with zero content restrictions for non-commercial/non-streaming sessions.

DISCLAIMER: Some renderings are alpha or prototype renderings liable to change as features become more robust. Not all assets used in renderings are owned by Vulcan Digital and each constitutes transformative work for the sole purpose of communicating project objectives, rather than any active use in a commercial service outside the bounds of current copyright law. As an ongoing project - if you have any concerns, questions, would like to suggest features on the project, or if you would like to see the current state of Radian in greater detail: please join our Discord community to make your voice heard. This is a tool by gamemasters, for gamemasters - we seek to elevate artists and creators in a cooperative environment without the overlapping costs of multiple parties each charging for the narrow piece of an author’s creative process that they can accommodate. At the end of the day, we strive to get people around a table in any form possible, craft impressive experiences, while lightening the load for storytellers wherever possible.
