I have created a custom appearance for "extruded aluminium"
which appears in a light blue folder in the appearances/photoworks
task pane. I'd like to use this appearance as a default for one of
our materials, "6063 aluminium". Can this be done? I think I know
the answer.... Any Ideas for workarounds if it cannot be easily
done?
You need to manually edit the materials database (preferably your company's and not the one installed with SW). Find the line that specifies the path to the appearance and replace that text with the full path to the appearance file. In our case the XML entry now looks (almost) like this
_/physicalproperties-_shaders-_pwshader2 name="matte aluminum" path="S:\Appearances\extruded aluminium.p2m"/-
In the above text I had to replace the less than symbol with "_" and the greater than symbol with "-" because they didn't play nice with the html.
