Lit Checkerboard

A static, lit checkerboard surface built on @builtin::shaders.lit_checkerboard — the default ground material for newly seeded worlds. It uses a neutral light-grey base colour (0.85, 0.85, 0.85) with a grey emissive tint (0.35, 0.35, 0.35) so the pattern stays readable in dim scenes, high roughness (0.7), no metallic, opaque, and instanced.

Inputs

• colors.base_color (0.85, 0.85, 0.85, 1.0) — neutral grey checker palette.
• colors.dark_color (0.35, 0.35, 0.35, 1.0) — the dark square colour, close enough to the base that the pattern stays readable in low light.
• floats.roughness (0.7) — mostly diffuse surface.
• render.instancing (true) — supports instanced draws.
