rk_tower

Material for the launch pad in the fx_launch scene, where the launch_fx Generator runs proc/launch.procGraph, a looping heavy-lift rocket liftoff. 71 entities wear it: the four 96 m tall tower columns (tower_col), the 64 cross members between them (tower_ring_x, tower_ring_z), all built-in cubes, and the three water_tank_band cylinders around the water tanks.

Shader: the built-in pbr shader, the engine's standard physically based material: the glTF metallic-roughness workflow lit by the shared pbr_shading model.

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: 0.55, g: 0.10, b: 0.06, a: 1.0 }: albedo, a red.
• roughness: 0.55: perceptual roughness.
• metallic: 0.3: partly metallic.
