Gloomhaven and Frosthaven 3D terrain with SOURCE

Last updated November 11, 2026.

Short answer: Use SOURCE to build Gloomhaven and Frosthaven scenario rooms in 3D. Lay out the room from the scenario book on SOURCE hexes, then play with your standees or miniatures on top. Raised hexes and walls make the room easy to read at a glance.

How to set up a scenario

1. Count the hexes in the room from the scenario book.
2. Lay SOURCE hexes or a foundation to match the room shape.
3. Use walls from SOURCE Adventures for room borders and doors, and stacked hexes for obstacles.
4. Place monsters, traps and treasure as the book shows.

SOURCE hexes are 45mm across, so the 3D room is larger than the printed map tiles. Use the SOURCE hexes for movement and range.

Which set

A SOURCE: Starter covers most rooms. Frozen Tundra suits Frosthaven, and Fantasy Forest suits Gloomhaven's outdoor scenarios.
