3DS Max to Lumion .fbx export issue

[Anonymous]

Hi, I've been trying to export an .fbx animation from 3DS Max to Lumion.

Cloth ModifierPath Constraint

The animations are Cloth modifiers (first image) and Path Constraint animations. Whenever I import it into Lumion (I've tried the tutorials on exporting as .fbx and importing .fbx animations into Lumion, setting it to 0,0,0, baking the animation etc) it just turns up empty within Lumion. If it helps, it does not turn up on Autodesk's FBX Review as well, and prior to importing it into 3DS Max I was modelling the components in Rhino as polysurfaces. I'm not too sure if I have inserted the keyframes properly as well for these animations(?). Is there anything within this workflow that needs to be changed for this import to work? Nothing I've tried seems to work so any help will be greatly appreciated, thank you!
