Hi,
I've exported a few guard character from iClone to Lightwave. It's the same mesh but they have different FBX motions assigned to them. One guard is sitting the other is standing with a idol motion. I have each character set up individually in a different Lightwave scene and I did a Load Items From Scene and imported each character into this existing scene.
The motions work fine in Lightwave when I'm setting them up and scrubbing through the timeline. When I do an Octane render or Open IPR it has the guard with the idol motion sitting doing the same sitting motion.
Lightwave 2019.0.3
Octane version 4.02.1.0 (Feb 12)
