The precision issue was related to vertex normals?

Then yes maybe that was causing much of the problems.

Yeah, if by duplicates you mean more than one normal that can happen to point in the same direction. Why is that significant for you?

But with the unwelded output, what it won't have is shared vertices, where 2 faces can have a single 3D point in common but have separate normals between them.

If you can get unwelded output to work properly, that would be a significant step, since MoI users could just uncheck that option when exporting to Octane.
