Make mat a transmissive (refractive) surface: the renderer grabs the opaque scene
colour mid-pass and the material refracts it, per KHR_materials_transmission +
_volume + _ior. Registers the scene-level transmission hook globally (idempotent),
which enables scene-texture transmission on every render task of any scene that
actually contains a transmissive mesh. Call before the scene is first built.
Refraction only engages when refraction.intensity > 0. Pair with
setPbrSubsurface for thickness/tint (volume absorption) and
setPbrDispersion for chromatic dispersion.
