Dear Michael, (or whoever can illuminate me)


I am trying to incorporate MoI into a workflow where I get CAD data from clients and make interactive Marmoset scenes out of them.
For this I imported a step model into MoI, deleted a bunch of faces and booled off a few areas which where on the inside.
I was completely done, everything looked fine in MoI, just as I wanted.



Then I wanted to import the model into Cinema4D (I found it has the best meshing algorithm around for my taste), but it was missing faces I did not delete after the import.
A short test verified that it is not an import problem from Cinema, as I imported the final 3dm file into a blank scene within MoI again and its missing the exact same faces:



Also, if I export the very first 3dm (where I hadnt booled yet) as STEP and import that into Cinema4D, everything works fine.
(Though the unoptimized mesh would be too heavy for interactive rendering...)

I can not send you the file, as it is under NDA. Would anybody have any idea what causes this behaviour and how to fix it?


Best regards,
Gustav
