Suggestion: Add metallic & pearlescent flake car paint materials to the library

Hi,

I’d like to suggest adding a new material group focused on automotive paints with flake effects — such as metallic, pearlescent, and sparkle car paints.

While it’s currently possible to manually adjust metallic, roughness, and reflection settings to simulate this look, having ready-made materials with built-in flake layers would save time and improve realism.

This would be especially helpful for automotive scenes or projects involving cars, where paint surface detail makes a big visual difference.

Thanks for considering this!
