op_orange_hull

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). One entity wears it: the cargo container cargo1, a built-in cube under Outpost.

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: 0.5, g: 0.22, b: 0.06, a: 1.0 }: albedo, an orange-brown.
• emissive: { r: 0, g: 0, b: 0, a: 1.0 }: black, so it emits nothing.
• roughness: 0.55: perceptual roughness.
• metallic: 0.35: partly metallic.
