Modular Blueprint Kit

A clean, low-poly modular environment kit with a blueprint grid aesthetic. 24 snap-to-grid pieces that let you build rooms, corridors, multi-level layouts, and more. All on a strict 1-meter grid.

What's Inside

24 modular pieces:

Floors (4)

• FL_1X1
• FL_2X2
• FL_4X4
• FL_8X8

Walls (11)

• WL_1X1
• WL_1X2
• WL_1X4
• WL_1X1_HALF
• WL_1X2_HALF
• WL_1X4_HALF
• WL_CORNER
• WL_CROSS
• WL_TJUNCTION
• WL_DOOR
• WL_WINDOW

Ramps (9)

• RP_1X2
• RP_1X4
• RP_1X6
• RP_2X2
• RP_2X4
• RP_2X6
• RP_4X2
• RP_4X4
• RP_4X6

Materials:

• Walls & ramps: square grid texture
• Floors: light square grid to differentiate from walls
• The kit uses just 2 shared textures:
  • prototype_grid_main.png - walls & ramps
  • prototype_grid_floor.png - floors

Color Palettes

3 complete sets included - each is a full batch of 24 pieces with matching textures:

• Blue (default)
• Yellow
• Green

Want a custom color? Edit or replace prototype_grid_main.png and prototype_grid_floor.png with your own textures, every piece updates after reloading the project. No need to touch individual materials.

Grid Specifications

• Grid unit: 1 meter
• Wall height: 3m
• Floor thickness: 0.5m
• Full level height: 3.5m (wall + floor)
• Naming convention: TYPE_SIZE_VARIANT

Every piece snaps cleanly to a 1m grid, no gaps, no overlaps.

Use Cases

• Level blockouts and prototyping
• Game jam environments
• Indie game production
• Procedural level generation
• Learning modular level design

License

You can use this kit in personal and commercial projects (games, renders, videos, etc.). Please don't resell or redistribute the raw asset files on their own, that's the only restriction.

If you make something cool with it, I'd love to see it!
