I’m trying to use Unreal Virtualization Tool with UE5.5 and Zen DDC.
In my opinion, structured data should be stored in perforce, and other large data should be stored in Zen DDC.
However, the command was executed successfully, and both the assets and loose data were uploaded to the same Perforce stream ( //depot/dev ).
project depot ： //depot/dev/Engine
DefaultEngine.ini ：
[Core.ContentVirtualization]
SystemName=Default
[Core.VirtualizationModule]
BackendGraph=VABackendGraph_Example
[VABackendGraph_Example]
PersistentStorageHierarchy=(Entry=SourceControlCache)
CacheStorageHierarchy=(Entry=DDCCache)
SourceControlCache=(Type=p4SourceControl, DepotRoot="//depot/dev"])
DDCCache=(Type=DDCBackend)
Some logs here：

1 What else configuration is required to save files to Zen DDC?
2 If these assets are updated, how to re-virtualize them by tool?
