I say this is very important, specially when u buy something from store. Peoples might want to adjust the texture scale of a specific texture map, and not of all at once.
Maybe i just want to make the noise from the roughness map smaller and not affect the scale my normal map, or my albedo. Or maybe i made a terrain, and later i want to change only my normal map and add a tileable normal noise, and i want to scale it in sansar, i need the ability to scale only for that specific map, and not all at once.
So a scale slider under each texture would be amazing. This feature will also help other shader types.
Thanks!
