So that's probably the problem.

Don't know anything about Modo btw and learning another software will make my brain explode

Else, I would suggest to import the .obj in Blender, clean the mesh, enable smoothing and then use Blender exporter to export to Octane.
EDIT: typo
Yes i tried, did not help.
And yes, good suggestion, i'll try to find out if it is possible to clean mesh in c4d or in sketchup.
Thanx, I got homework to do and will get back when next wtep is made hopefully.
Otherwise I'll take a look at Blender, only learned about the existence a while ago.
Maybe I made the wrong choice buying c4d while ago, maybe not

I'll find out in time.
Greetz and tnx for info and suggestions
