Which metals and gemstones are in the library?
Every part is a metal, a stone or another surface. The library holds 19 metals (gold in every karat and colour, platinum, silver, black rhodium and anodised colours), 51 gemstones in 6 groups (diamonds, precious stones, coloured stones, two-colour stones, with inclusions and opaque stones) and 36 enamel, ceramic and pearl surfaces. Stones refract light with their own refractive index, dispersion and colour; the gemstone pages list the values.
Select a part in the view or in Materials, then choose from the library. Auto assign does it for every part from the part names (see how names become metals and stones).
Finishes
Metal parts can be polished, brushed, satin, hammered, sandblasted and patina. Each sets the metal's roughness, and every finish but polished has a Finish relief slider for the depth of the grain. Finishes show in Interactive, in Render and in the GLB export; check the grain around curved surfaces before exporting. Each finish, rendered.
Looks and lighting
A look changes the lighting, the backdrop and the ground in one click, returns the camera to the Beauty view, and leaves the design, its materials and the stage alone. There are 4: White e-commerce, Black velvet, Warm lifestyle and Floating. Under them sit 5 lighting environments, Softbox, Jeweler, Daylight, Golden hour and Noir, which you can rotate and brighten, or replace with your own HDRI lighting maps.
Automatic setup
Automatic setup guesses what the piece is from its name and shape (a ring, a necklace or pendant, earrings) and sets the stage to match: a ring goes on a hand, a necklace on a neck, earrings float. It then sets the framing, light and exposure. Your materials are kept. It shows why it guessed what it did; the guess is a suggestion you can change.
