Materials under one light

When skin, fabric, glass and metal share one key, say how each one answers it.

Materials under one light [official guidance]: where several materials share a key, the prompt says how each answers it. "A soft sheen on her cheek, one hard glint on the steel tap, no shine at all on the cotton."

One sheen on every material is a tell. Real skin, wool and chrome take the same light in different ways. When everything shines alike, the frame reads as rendered. The fix is the same sentence: say how each material answers the key, and give the TEXTURE block its wear signs (see Making it feel real → The "too perfect" tells). The client's product is always pristine (decided): no wear and no signs of use (see Making it feel real → Skin, make-up and wear with a history).

The reference bar checks it under its Surface point (see The quality bar → The reference bar).
