Shading problems when importing from MOI>Cinema>Keyshot

[Andrew_G]

Hi,

I have some problem with importing files that were created in Moi3d. When I finish modelling in Moi, I import file into C4D where I clean some stuff and UV unwrap some elements. Then I want to export this into Keyshot. Unfortunately I have some errors with shading. It concerns almost every file I work in. It looks like in the image that I attach. Is there something I can change to fix it?
