A flexible sandbox for player-made scenarios, house rules and Game Master-led stories. Build your own encounter and decide what happens next.
TACTICAL SQUAD / SKIRMISH
A crossing worth
fighting for.
Industrial Crossing: a 6 × 4 foot battlefield built around a shattered overpass. Marines deploy around a pipe-generator supply yard and rocky ridge; orcs muster beside the eastern refinery and ruins. A broad contested centre separates the forces, with room for vehicle movement and a southern bike flank.
Cover with a purpose. Container stacks shelter the marine supply yard. Ruined factory walls and a broken overpass divide the centre into firing lanes, while rubble and half-walls give the advancing infantry successive positions.
High ground. A narrow crossing. Sculpted ridgelines overlook winding dirt and gravel routes. A recessed, rock-lined pond constrains the northern approach; the southern route gives the orc bike a flanking lane.
MEASURE THE NEXT MOVE
Ten inches.
A new position.
The game’s measuring tape is pulled out and locked at 10″ beside a marine, illustrating a movement measurement. The displayed distance is measured in board inches.

FROM YOUR COLLECTION TO YOUR TABLE
Your favourite map.
A new dimension.
Load a Universal VTT as your gameboard, or reconstruct its walls and doors in 3D. Have a dungeon image instead? Extract a floor plan, review it and build a 3D starting point.
Runs locally. No AI service required.
Automatic conversion builds walls, doors and floors. Add furnishings from the catalogue afterwards.
Supported VTT files and limits
- .dd2vtt, .df2vtt and .uvtt. Generic .vtt / .json files must contain Universal VTT data; Foundry scene JSON is unsupported.
- UVTT versions 0.2–0.x, with embedded PNG/JPG artwork. UVTT 1.0 and WebP are unsupported.
- Up to 32 MB, 4096 pixels per side and a 128 × 128 whole-cell grid.
- 3D reconstruction requires supported wall metadata. It builds structural geometry only, without guessing furniture.
01 / UNIVERSAL VTT
One map. Two ways to play.
This crypt comes from the VTT in our reference folder. Its grid, wall lines and portals drive the conversion into catalogue floors, walls and doors.
A 24 × 21 map, aligned one VTT cell to one board cell. Play directly on the artwork; its printed walls are visual in this mode.
Keep the art, or build above it. The 3D result uses editable catalogue pieces and retains the artwork underneath for comparison. This example converts 216 floor cells, 68 authored wall segments and all five authored doors. No furniture is guessed.
Authored wall coordinates, portal positions and open states are retained. Floors are inferred from enclosed wall geometry, using the original source context for cropped exports. Local surface analysis estimates materials; catalogue pieces supply height. review exporter-specific LOS blockers and openings.
02 / A DUNGEON IMAGE
From a picture to a place.
A separate example, using the PNG from the reference folder. Detailed contour tracing retains the round central chamber, rectangular side rooms and entrance niches. Generate the structural base, then furnish it from the catalogue.
Choose the floor. Keep the detail. Generate solid 3D tile floors, or keep the original image visible beneath the 3D walls and doors. For PNG maps, mark door positions in the review pane; VTT conversions retain the file’s authored doors.
Review the plan. Make it yours. Preserve image proportions, adjust the threshold and rotation, clean small gaps, or paint and erase cells. The converter selects installed catalogue pieces that fit the chosen theme and grid dimensions.
Both examples are actual local conversion results captured in Unity. Image-only tracing remains approximate: review its floor mask, dividers and openings. VTT metadata gives the structural converter more precise wall and portal coordinates. Furnishings are placed separately.
THREE MORE MAPS. THE SAME LOCAL CONVERTER.
From downloaded map
to editable board.
Three distinct maps downloaded from a public map collection and run through the in-game Universal VTT converter. Compare each original 2D map with its actual 3D result.
03 / DUNGEON / FIRE ROOM
A chamber above the fire.
The authored outline becomes a stone chamber with four passage openings. The orange lava remains part of the flat reference artwork; it is not generated 3D terrain.
04 / CAVERN-STYLE / GOLD ROOM
Follow the shape of the cavern.
The source boundary is rebuilt with repeated catalogue cave-wall modules, cave earth tiles, rocks and stalagmites. Wall profiles retain their native proportions. Gold piles are not identified or reconstructed.
05 / ACADEMY INTERIOR / NORTH ROOMS
Wooden rooms. A stone passage.
A wide interior from Stone Resolve Academy, with wooden floors beside a tiled central passage. Tables and chairs remain in the source artwork; the conversion builds the structural base.
These examples use Universal VTT wall metadata plus the embedded 2D artwork, rather than image-only tracing. Catalogue pieces approximate surface materials and height; boundary detail can differ. No furnishings are inferred. Map credits and reuse details ↗
05 / GIVE YOUR HERO A SIGNATURE
A spell worth
putting your name on.
Design abilities for your heroes and enemies. Build a frost nova, a line of lightning or an explosive ranged attack—and save the recipe for another adventure.

It still feels
like tabletop.
The reach across the board. The careful measurement. That pause before the dice settle. The little things are part of the adventure.
D20

BEFORE YOU TAKE YOUR SEAT
A few
good questions.
Is Hammer Foundry a game or a world builder?
Both. Play the authored Derelict Signal campaign, build and populate your own worlds, or run an open-ended tabletop session with a Game Master. The campaign and custom sandbox have separate rules and abilities.
Can I play the campaign on my own?
Yes. Single player gives you control of all five marines. In a shared session, the host can assign marines to different players.
Can an image become a 3D dungeon?
A PNG or JPG bird’s-eye reference can be used to extract a floor plan. Review and edit the detected walkable cells, then generate and customise the 3D layout. It is a guided reconstruction workflow, not a guarantee of an exact replica from any image.
How does multiplayer building work?
Players join the host’s Steam session. The map transfers before they enter play. The host can invite a guest to build assist, giving them access to placement and adjustment tools while keeping map generation under host control.
Can I bring PDFs to the Game Master screen?
Yes. Load PDFs from your game’s REFERENCES folder into up to three private, floating readers that you can place in 3D space. Flip through pages, jump to a specific page and search the document. These readers are local to the Dungeon Master and are not shown to other players.
When and where can I play?
Hammer Foundry is in development with PC VR beta as the first target. A public release date and Steam store link have not been announced on this page.
