A tip for those who render MoI scenes in Blender…

MoI allows export of styles as vertex colors when using the FBX format. This can be enabled in MoI.ini by setting:

[FBX Export]
WriteVertexColors=y

Optionally, you can change the FBX version using "FBX Version=" , e.g. FBX Version=2016

Once imported in Blender, remesh objects with sufficient detail in Sculpt Mode, with Preserve Attributes checked, then use Color Filter tool ➔ Smooth to smooth vertex paint borders.
