Hi
I also still use Iclone 7 and 3DXChange pipeline
If you really need higher quality than the Iclone native render
engine you can export to the free unreal engine or to the free Blender programs.
Also if you upgrade to Iclone 8 and you have a decent NIVIDIA RTX card
you can export to the free omniverse app which is like Daz Iray but realtime rendering
Reallusion has many Free tools to help you export to better render engines.
