I watched a few recent youtube videos posted by Bentley about integration of Synchro to LumenRT via Synchro Control Cloud services. I have no need for cloud services. Can I just export either an FBX or SPX from Synchro and open it in LumenRT?
Yes you can import .fbx file inside LumenRT but it will not have SYNCHRO animation sequence attached to it, only 3d model will appear.
If you want the animation to work you can only go through Control cloud services.
