* Will prevent AWS buildmachines from holding an exclusive lock on actor files in case of a crash & if the Horde process doesn't cleanup checked out file properly (often the case)
* All p4 operations were temporary during those two steps those anyway
* Much faster setup step
The last step, -SubmitHLODs will obviously require source control to be enabled

* Added options to generate/use a build manifest
* -BuildManifest=Filename.ini
* When calling with -SetupHLODs, provide "-BuildManifest=Filename.ini -BuilderCount=N" to have N workloads in the build manifest
* When calling with -BuildHLODs, provide "-BuildManifest=Filename.ini -BuilderIdx=i" to build workload i
Added UWorldPartitionBuilder::PreWorldInitialization()
Added support for distributed World Partition HLOD generation
* Runs multiple steps on different machines
* Setup: Done on a single machine, will create/update/delete HLOD actors as required. The distributed setup step takes a "BuilderCount" argument, which will be used to write a build manifest that specify the work that needs to be done by the N builders
* Build: Performed on multiple machines, read work to be done from the build manifest
* Submit: Final step, perform on a single machine. Gather files modified in all the previous steps and submit them in a single changelist
Intermediary files that are created/modified/deleted are transfered between the jobs as build products, and submitted in the last step.
To run with UAT:
RunUAT.bat BuildGraph -Script=Engine\Build\Graph\Examples\BuildWorldPartitionHLODs.xml -Target="HLOD Generation" -set:ProjectName=YourProjectName -set:EditorTarget=EditorTargetName -set:MapName=YourMapName -set:BuilderCount=N
To run steps individually:
* Setup (N = Builder count to use)
YourProject YourMapName -run=WorldPartitionBuilderCommandlet -SCCProvider=Perforce -AllowCommandletRendering -Builder=WorldPartitionHLODsBuilder -SetupHLODs -DistributedBuild -BuilderCount=N
* Build (i from 0 to N-1):
YourProject YourMapName -run=WorldPartitionBuilderCommandlet -SCCProvider=Perforce -AllowCommandletRendering -Builder=WorldPartitionHLODsBuilder -DistributedBuild -BuildHLODs -BuilderIdx=i
* Submit:
YourProject YourMapName -run=WorldPartitionBuilderCommandlet -SCCProvider=Perforce -AllowCommandletRendering -Builder=WorldPartitionHLODsBuilder -DistributedBuild -SubmitHLODs
