Derived Data Cache AWS S3

Hi,

I’m trying to set up Distributed Derived Data Cache (DDC) with Amazon S3, but I’m having some issues. My current configuration in DefaultEngine.ini looks like:

[DerivedDataBackendGraph]
MinimumDaysToKeepDDC=7
Root=(Type=KeyLength, Length=120, Inner=AsyncPut)
Inner=(Type=Hierarchical, Root=Cloud)
Cloud=(Type=S3, Host=“*“, Region=”", BucketName="l", AccessKeyId="“, SecretAccessKey=””, bAllowS3Storage=True, MaxCacheSize=5120)

I have a error “LogDerivedDataCache: Cloud: Disabled because Host is set to ‘None’”

Has anyone successfully set up DDC with S3? Are there any additional settings or steps I should follow to make sure everything works properly?

hi @maciek1906 ,
The main documentation is in Engine configuration for UE 5.5 BaseEngine.ini
starting line 2575 with all the parameters
