I updated the plugins this morning, can you try and check the latest from our site?
I've installed the plugin-3.2...oh, now we can get NURBS via plugin, thanks!
BUT, object grouping got worse!!
My sample data is renderd as a pure panel without no characters:)
It looks that plugin-3.2 can't recognize the colors of quilts in a Creo part file...see the 1st attached image in this post.
BTW, there has been completely different behaviour between 'import via plugin' and 'direct import with KeyShot ~5.0'.
In plugin case, the same color objects, which are different objects in Creo,
are forced to merge into one object in KeyShot model tree.
The 2nd attached image shows this...so, the plugin takes care of only colors.
In direct case, KeyShot ~5.0 cleverly recognizes different obejects with the same color in Creo.
The 3rd attached image shows this...so object distinction in Creo holds higher priority and color is optional,
in direct import case with KeyShot ~5.0.
...I definitely love the latter, the behaviour like direct import with KeyShot ~5.0,
and it's more critical than NURBS support or not in plugin, at least for me.
I won't use the plugin and KS5.1.x itself until they support the 'right' object sensitive import mode as KS~5.0 described above
