Glass

Clear glass — a smooth, transparent PBR surface with a faint blue tint (0.9, 0.95, 1.0) and low alpha (0.3). Rendered in the transparent queue with backface culling off (cull: none) so both faces of thin geometry show. Built on @builtin::shaders.pbr.

Inputs

• colors.base_color — tint and opacity (the alpha channel drives how much shows through).
• floats.roughness (0.0) — perfectly smooth; raise for frosted glass.
