Appendix I - How To Open a Project with Rgraph using Command Line?

Open a command Line and Go to where your Reality Engine is! In Our Case :

 cd C:\Program Files\Zero Density\Reality Engine\2.8\Engine\Binaries\Win64\

Execute The RealityEngine.exe with CookedProjectPath((Mandatory)) -ShaderCacheDir (Mandatory) and -Rgraph (Optional) parameters.

For our instance : 

 Our CookedProjectPath is : R:\Reality\Cooks\OriginalStarter\ZDStarterMap\StarterProjectCook310\1d4f4290de58421d92278677ebb5e504\WindowsNoEditor\OriginalStarter\OriginalStarter.uproject
-ShaderCacheDir path is : R:\Reality\Cooks\OriginalStarter\ZDStarterMap\StarterProjectCook310\1d4f4290de58421d92278677ebb5e504\WindowsNoEditor
-Rgraph path is : C:\Users\Reality\Desktop\Rgraph\ZDStarterGraph.rgraph

As a result our command will be following line :

RealityEngine.exe R:\Reality\Cooks\OriginalStarter\ZDStarterMap\StarterProjectCook310\1d4f4290de58421d92278677ebb5e504\WindowsNoEditor\OriginalStarter\OriginalStarter.uproject -ShaderCacheDir=R:\Reality\Cooks\OriginalStarter\ZDStarterMap\StarterProjectCook310\1d4f4290de58421d92278677ebb5e504\WindowsNoEditor -Rgraph=C:\Users\Reality\Desktop\Rgraph\ZDStarterGraph.rgraph
