As Unreal Live Link does not transfer my subprops but a so called "iProp" does work,
how do I make such a thing??

Aha! So you are going to animate using bones after all. :)
iProps are props animated with bones with animation recorded to Perform action.
A drawback is, that Perform action in IC7 is broken: https://www.reallusion.com/FeedBackTracker/Issue/Adding-to-Perform-creates-12-16-static-frames-at-the-beginning-of-the-clip/1/Perform
But you may just create clips and apply them where you want it.
Rotation works just fine but you have to rotate Gizmo manually - cannot write the value.

That is all true for a single prop - which is what you need?

Well, this would be in case I don't find an "Unreal-internal" solution for the cars.
BUT, working with Gizmo without "write value" is NO option... :pinch:
There are probably other things I will need where this approach works,
but for the cars I don't really see how it could work properly, without "hick-up"...

@RL
We really need a "write value" option in "Edit Animation Layer" to raise the bar...
I have no clue about programming but is it really so difficult/too much to "change/implement"/... to get that working?

You may convert your car to non-human and animate bone rotations with values in Curve Editor

Actually you do not even have to convert. I tested this car and it works as is - a prop.

Oops, never thought about this approach.:crazy:
Will try that out immediately! (hope I do the 3DXChange process correct :blush:)
Will see what happens... Thanx :P

Done that, not sure how to start in Curve Editor...
Or do I have to start with Edit Animation Layer to have a "start animation" at all to work with?

There:

Got it...
Surely needs a bit practice, but it works!
If it works with Live Link, that's definitely a usable approach... :kiss:

Hm, can't you copy keys in Curve Editor??


Toystorylab on Vimeo :     Crassitudes (my "Alter Ego") on Youtube: 

You have to add a key first. Either on a timeline or in Curve Editor and then just copy/paste values.
But the clip must be there already before you can manipulate keyframes in Curve Editor
So create a clip be entering a key at the last frame on a timeline (you may delete that key afterward).
And now you may manipulate keys (add/remove) in Curve Editor only.
