Thanks for the chart Marco, that clears things up nicely, hopefully this will help too ...

KeyShot Pro version 5 Imports the following formats and supports these MoI object settings

fbx = no style - no object name
iges = style colour - no object names
obj = style colour - yes object names
sat = style colour - no object names
skp = no style - no object name
stp = style colour - no object names

KeyShot 5 Pro will import 3DM files from MoI but ignores ObjectNames however it will import the StyleName and StyleColor. But does not support multi-style solids.
