While using control rig, it doesnt let me cook my projest and all animations have an error like this
Hello there @AnaGarcia !
From your log extract, I think the main conflicts is here:
Assertion failed: bRequiresModelPopulation DataModel != nullptr DataModelInterface != nullptr
Invalid Animation Sequence base state, no data model found past upgrade object version.
This refers to data corruption in certain animations, most likely tied to version conflicts, either with a plugin, or the engine itself. So, the first question would be, have you recently updated your UE version, or are the affected animations migrated from an older build? For either case, the affected animations should be re-imported:
-
Open the affected animations, right click on each one, select Asset Actions, then Reimport
-
Next, repeat the process, applying Fix Up Redirectors
-
Finally, do the same with Validate Assets, which will rebuild asset data
If the issue persists after these steps, we can also try a cache clear, via closing UE, navigating to your project location, and deleting folders Intermediate and Binaries from the main directory. After that, restart UE, and allow it to rebuild the project.
