3DXChange 7 has had import issues since iClone 7 (and possibly earlier). This video shows how the import function fails to import relatively simple meshes properly and shows how this functionality still has not been fixed in iClone 8. There are also a slew of export issues which have not been fixed since 3DXChange 7i / Clone 7 but this video will focus on demonstrating the import issue with a sample asset. It should be noted that the asset was created in Blender software which is a common, free, and powerful software used by a large portion of the 3D content development community (i.e. it was not made with some small obscure software).
As can be seen the import function does not render geometry correctly. The video shows both shape issues (such as the pin being distorted) and face issues (such as the pin hole and the cutout being covered).
