Hello dear Michael and community.

I have created a model in MOI3D and I want it as a high poly model in my 3D software (Cinema4D) so I can work further on texturing/materials and rendering.
When I export it as an obj I get a horrible topology with which it is super difficult to work. For example, I want to select this section to put a different material than the body and so on but it would take a lot of time to select every triangle of that selection/edge to have a clean selection of that surface. Is there a workaround?

(exported with only triangles)




Also when I export it with n-gons and triangles I get a more clean topology with which I can work but I get a lot of broken artefacts.



What is the usual useful work process to export the object in high poly and further work in other 3D programs with that model?

I also uploaded the moi3D file of the model if needed.

Thank you in advance
