Why MeshStandardMaterial does not show scale roguhnessMetallic texture?

I have model which has scale in metallness roughness texture, but scale not shows in MeshStandardMaterial, metalnessMap and roughnessMap repeat after load gltf in three equals vector(3, 3). MeshStandartMaterial can’t shows repeat in roughness and metalness?
In others viewers works fine.

What you see is a current restriction of the engine. three.js can only handle one texture transformation setting for the first uv channel. Since the shield’s material uses a diffuse map, its transformation is prioritized and applied to the roughness/metalness map.
