Maybe you should start learning something about materials and their components first... this applys to any renderer not only maxwell. Maxwell for Sketchup is a bit limited when it comes to more complex materials (compared to the Render Suite), but starting with an AGS or glass material and adding a bump or normal map should be possible... http://support.nextlimit.com/display/maxwelldocs/SketchUp http://support.nextlimit.com/display/maxwelldocs/Maxwell+Materials
