op_cyan

Material for the outpost under the energy-shield dome in the fx_shield scene (the Outpost entity at (110, 0, 150), the dome's centre). Six entities wear it: three parts of the proj_ column at the outpost's centre (the sphere proj_core, the upper torus proj_ring1 and the thin cylinder proj_glow_band) and the door of each of the three habitats (hab_door).

Shader: the built-in pbr shader (@builtin::shaders.pbr), the engine's standard physically based material: the glTF metallic-roughness workflow lit by the shared pbr_shading model. Its glow output is emissive times emissive_intensity (default 1.0) times the emissive texture (default white).

Render state: the defaults (opaque blend, back faces culled, depth write on); mat.yaml sets only the shader and its values.

Properties

• base_color: { r: 0.02, g: 0.1, b: 0.15, a: 1.0 }: albedo, a dark blue-green.
• emissive: { r: 0.1, g: 0.9, b: 1.4, a: 1.0 }: cyan glow colour.
• roughness: 0.3: perceptual roughness.
• metallic: 0.0: dielectric.
