An update of an existing preset (found here Metals>Ships>Etched Blue Metal).
Taking advantage of 7.1 pro feature. Anisotropy and enhanced bump response for spherical mapping modes. High frequency brushed bump effect has been combined with existing texture channel. Reflection has been set from 25 to 0 to improve render response. This is easily restored if reflection is required, but anisotropic response will under most circumstances simulate the effect of material reflectiveness without the same overhead. Material now appears more like anodised aluminium as a result of the modifications.
