Loading Sketchup materials into Plusspec

How do I load my collected Sketchup materials into Plusspec.

I have not kept a file of the original materials and only have the .skm files within the Sketchup Material’s folder.

I could edit each material and save a jpg version, but that would seem particularly longwinded.

Is there a more direct route?

Hi I have answered your question in your other post, my apologies for the delay mate.
