When project is reopened, functions related to spline(spline from points, transform/position from spline, draw spline tested) get unplugged and message “node could not be resolved” appears. Reconnecting these nodes doesn’t help, but if they are deleted, rig compiled, and same nodes created it has no compiler errors. What’s the reason behind that strange behaviour.
“Node Spline From Points could not be resolved.”
same here. This happens each time your open the project. very annoying!!!
Update: it seems related to migrating the entire project.
In the log I can see errors:
LogRigVM: Error: No handler found for function ‘FRigUnit_ControlRigSplineFromPoints::Execute’
LogRigVM: Error: No handler found for function ‘FRigUnit_PositionFromControlRigSpline::Execute’
These also appear for any other control rig using these functions.
Even in the migrated project!
I created a new 5.3 project and migrated only the control rig into it. That worked fine.
Well, until I started migrating other stuff into it, the error returned.
The thing that solved it was changing
“LoadingPhase”: “PreDefault” in ControlRigSpline.uplugin stored at
<engine_install_dir>\Engine\Plugins\Animation\ControlRigSpline

Changing from “LoadingPhase”: “Default” to “LoadingPhase”: “PreDefault” seems to resolve the problem for me. THANKS for the hint!
Thank God I found this post. This issue has been driving me nuts for days. Is this a bug?
