What is the best way to apply imperfection textures to models?

Hello. I commonly use imperfection textures of scratches, fingerprints, dust, and water drops on the surfaces of my models when rendering with nodes (principled BSDF) in Cycles. It looks fine until I select the Sneak Peek button, and then any scaling I’ve applied to the imperfection textures appears to change back to a default value of 1.

Is it possible to modify texture properties/values in Verge3D? If not, is there a good work around?

Thank you
