importing models different with keyshot 8

[XD1]

so was the importer changed for keyshot 8? i didn't click anything in 7 and now when importing with 8 it groups things. so less parts or surfaces came in that were painted. if i click object it would seem like it breaks it out properly. that option was there for 7 and i never used it. also what is separate materials by part?
i click it and can't see what it does...

i've noticed also errors between surfaces when having a surface on a solid. can't remember if this was a thing before but i didn't seem to have an issue in 7. you have to move it just so slightly...or am i wrong here?

is it me or does it seem a few cool things are added but a lot is changed like simple things that you have to relearn. like label projection vs planar
