Utilities 2 - Vol5 - Materials inputs

to be of immense value when importing Sketchup models for setting up and rendering in Poser Pro 2012.  I bought it at full price, though.  

That one, and Snarlygribbly's Scene Fixer python, are very helpful for getting rid of shader node setting artifacts when a Sketchup-exported OBJ is imported into PP12.

( I can't seem to locate a current link to the SceneFixer script, unfortunately).
