Especally any slider could be used by mistake. as in the image an indicator could help previous position but to go back to it, ı suggest a double click to undo last action.
second suggestion is Each manipulation of any material, light etc. acts as a “session to save” so if we want ot cancel there should be a button to “reset to previous”
these requests are needed when a customer demands something then changes his mind back to previous request. or you are just testing ideas.
