Physically based rendering uses standardized material properties, commonly base color, metallic, and roughness, so surfaces respond consistently to lighting.

Read channels separately
Base color describes intrinsic surface color, roughness controls highlight spread, and metallic selects conductor-like behavior. Normal and opacity maps add detail or cutout behavior.
Inspect generated PBR data
AI-generated maps can look convincing in one render while carrying baked shadows, inconsistent values, or alpha settings that do not transfer to another engine.
