Hi, With the new version of Keyshot and reference Sketchup 8, unfortunately Keyshot does not import materials that have been applied to sketchup object "groups". It works OK if you apply materials to every face within a group and then import, but that can be a lot of work!
Thankfully you have maintained a "Use old importers" selection so I can carry on using Sketchup 7 format saves. Although these now get flipped 90 degrees when imported. A bit frustrating.
Hopefully you will refine the Sketchup 8 importer for the next release.
Cheers, and keep up the good work
Kevin.
