Texture material maps
1024 x 1024 pixels

Base color: use sRGB. All other maps: use Non-Color / linear data.
Normal format: opengl. Invert the green channel if your renderer expects the other format.
Roughness: white is rough; black is smooth. Height: white is high. AO: white is unoccluded.

These maps are artistic estimates derived from an image, not measured physical material properties. Check scale, relief, and repetition in your renderer. No metalness is inferred.
