Physical Size in Unity

The physical size feature in the Substance 3D plugin for Unity allows Substance materials to be applied and scaled based on their real-world sizes. The dimensions are set in Substance applications like Designer and shown in the plugin panel's Physical Size section.

The feature is currently available only for HDRP workflows.

With Physical Size enabled, the materials will tile based on their real-world size in centimeters. The material tiling will remain the same regardless of the object's scale.

The feature can be enabled by toggling "Use Physical Size" in the plugin panel UI. The Physical Size values can be overridden for artistic control over the material tiling.
