Wet ground needs more than a darker color

The ground-material experiment treated wetness as more than a color adjustment. It worked with surface detail, roughness and the underlying color together. Those properties affect how the ground catches light, how sharp a reflection appears, and whether the detail still belongs to the same surface.

This was an optional development trial, kept separate from a general change to the game. That boundary made it possible to inspect a particular look without presenting every experimental setting as the new normal. The work also preserved the existing tool and mining behavior around the scene.

The trial was about the material itself; it did not add rain or simulate puddles. It also offered a useful reminder that an environment is a collection of surfaces responding to the same light. Ground that looks convincing in isolation still has to sit comfortably beside the rocks, plants and water around it.
