Oh boy.  I took your advice.  I almost gave up.  Their forum is not user friendly. (Or better, not nicely organized in topics like yours)  I did see that there were several posts requesting an API, which were declined.  I requested again, and specifically mentioned LandFX.

Which reminds me... have you ever watched spongebob?  There is this awesome episode where SB is being bullied by "Flats".  He tells his teacher, but asks her not to say anything... but of course the next time they talk, she says "I talked with Flats, He is fine, I used your name, its all good."... Meanwhile, Flats is behind the teacher giving him the hairy eyeball and punching his hand.

I did that to you.  I went to Lumion and said its LandFX.  Lumion is probably standing behind me now :)

I hope not...  And I hope they come up with a way to make it more interoperable.

Meet you in the other post.

For now, this is solved.
