clear
A built-in Glass style that prioritizes visibility of content behind the material.
Its shallow blur stays constant across material sizes while its authored refraction and distinct edge and lighting response remain recognizable when a renderer simplifies advanced optical effects. Its ordinary material response is the same in light and dark appearance; reduced transparency may use an appearance-dependent opaque fallback. It writes the complete material response while preserving separately composed shape, background colour, tint, alpha, light position, and interaction presentation.
