Designer to Painter, forced to disabling maps.

Hello,

While everything looks fine in Designer (cloth simulation model), while the model without textures looks fine in Painter (smooth surface), when it comes to apply my material, I meet two problems :

- roughness seems inverted : rough in designer become shiny in Painter

- the object looks smooth without normal map, and when the normal map is applied, the object becomes edgy/faceted.

Any hint?
