Verse

Summary

After today’s update, my Fall Guys project suddenly started having Verse build errors when opening the map. The errors reference files that I cannot access and cannot inspect for issues. My verse devices/files do not have any visible errors; the only change since I last saved the project was the addition of a “hextile” verse tag. These errors persist on all previous revisions available in Revision Control. I fear I have lost all of my work on this project and desperately would like some support in restoring my project.

Steps to Reproduce

Open my Fall Guys project from the UEFN Project Browser

Expected Result

Load without errors, as it has been the last time I have worked on this map.

Observed Result

Verse Build Errors referencing SceneGraph entities in a project that does not have SceneGraph enabled. Also, Assets digest is failing to generate due to potential clashing names that I cannot identify in my imported assets.

Verse build errors found while opening the level:
/SkyRace/SkyRace

If you continue to open this level without fixing the errors, behaviour that depends on Verse may not work. Saving the level while in this state may cause data loss.

If possible, fix these errors in VSCode and rebuild.

The assets digest could not be generated. Please ensure that your imported assets do not have names that clash with existing Verse symbols.

I have continued trying to troubleshoot this issue without much progress.

If I enable Scene Graph, which stops me from publishing my project, the errors are ignored, and Verse builds successfully.

Is it possible to find those files it is referencing so that I can see what is triggering these errors? They are not found at the path listed in the error.

For anyone who is experiencing this since the 31.00 update, make sure that you don’t have any materials with exposed parameters named ‘texture’ or some other existing Verse symbol name

This ended up not being my issue. As far as I could tell, my assets digest not generating was due to the previous errors. After sifting through all of my imports, I found the offending asset.

Early in my testing for this project I was trying to construct a blueprint building prop that was a combination of a few Fall Guys assets. One of those attempts was to choose the “Entity Prefab Definition” from the list of options under Create Basic Asset. This didn’t work, so I moved on but left the asset in my project. After a few full-time weeks of continuing to develop my project, the asset was buried and forgotten about. As of this 31.00 update, something changed with Scene Graph that caused this error, even though my project structure hadn’t changed. I removed the “NewEntityPrefab” test asset and rebuilt Verse. This was successful, and my project is functioning again.

Thank you for letting us know!

I am getting very similar error. I am not using anything from scene graph. Whenever I add a new verse file to my project i get this error. If I remove the verse file it goes away.
