The Grid Material Trick I Wish I Knew Sooner

Main ideas / lessons

• Problem with plain gray blockouts: Using a single flat gray material for all surfaces makes layouts hard to interpret—rooms, wall heights, and jump distances blur together.
• Solution: Use a grid material during blockout instead of flat color so level design becomes easier to read, build, and scale.
• Why it matters: A grid material improves three core areas:
  1. Measurement (accurate scale at a glance)
  2. Readability (clear spatial separation and legibility)
  3. Communication (team members instantly understand intent)

Method / instruction details (as presented)

Use grid materials during blockout (before detailed art)

• Block out the level using simple shapes to test layout, flow, and space.
• Replace flat gray surfaces with a grid so the environment reads spatially and consistently.

Set up the grid for measurement

• Make each grid cell a fixed real-world size.
• Example given:
  • Each large square = 1 meter
  • Include smaller subdivisions inside cells for finer detail.

Result: You can visually determine hallway width, doorway height (e.g., human height), and whether jumps are actually clearable without measuring manually. The blockout becomes “to scale” instead of guesswork.

Improve readability (visual clarity)

• Use two line weights:
  • Bold lines every 1 meter
  • Finer lines between them
• Add an extra readability trick:
  • Darken the top spaces of surfaces to instantly separate floors vs. walls.

Result: Even a busy blockout stays easy to read at a glance.

Communicate intent using the material (team workflow)

• Apply different colors to mark purpose directly in the gray blockout:
  • Cover
  • Spawn points
  • Hazards / objectives

Result: Designers, artists, leads, and animators understand each area’s function before assets exist.

Use grid alignment settings (workflow / iteration)

• Choose where the grid “locks”:
  • Lock grid to the world so everything aligns like graph paper across the whole level.
  • Pin the grid to each object so it moves with the object during iteration.

Material sourcing / availability (as mentioned)

• The speaker’s exact gray/grid materials are available via Gumroad.
• A link to the exact setup is referenced as being in the video description.
• Key takeaway: even if viewers make their own, the principle holds:
  • Try a gray/grid material rather than flat color for faster building and better readability.
