Thanks for all the help Richard, can i apply a bump map directly in sketch up through the maxwell plugin interface, or is this something that has to be done in studio ? I am guessing mapping the crack in the wall in the centre of the image would be difficult to position, the glass bump would be easier.
Position your bump map to the model in SU, this will by default set it for both the bump map and colour map.
In the plugin material editor bump channel under source set to "use specific texture" and link to the same map externally,
In the colour map channel again select "use specific texture".***
This should drop the colour map from this material yet maintain a bump map that utilises your UV's. Use this method for both your wall map and glass bump.
*** you may want to use a map here with a VERY low contrast mottling created using your wall colour and a slightly off tone mixed using photoshop's Filter > Render > Clouds.
