My object models have artifacts and look odd when imported into Unity, what can I do to fix?

Question

I have made some heart models on medical software Materialise Mimics and have exported them as .obj files because the software doesnt support exporting as .fbx.

I've tried other programs who perform a similar function and the models work fine on them, but I dont know what they've done to process the files.

I'm quite new to unity and have tried following some guides on making materials and shaders, but nothing seems to work.

Cant seem to upload a sreenshot so Il include a google drive link: https://drive.google.com/drive/folders/1u6CfSaSweu-lrjCzLRvNUJ800ZIQ8S-V?usp=sharing

Thanks!

You could try import it to Blender and than export it as a fbx (as a first work arround) (at least to see it is really .obj related or something else)

You definately would try to import object to blender and recalculate its normals outside cuz if some polygons are not displayed they probably are facing different dirrection and not render properly. The guide how to recalculate normals is here, than export it as fbx and make sure to import only selected objects if you have something else on your scene.
