I have already used: Multi-User Editing Reference | Unreal Engine Documentation
As well as: https://cdn2.unrealengine.com/unreal-engine-remote-multi-user-editing-guide-404332864.pdf
And have built a complete Stand Alone Unreal Multi-User Server in GCP utilizing this as a base: https://cdn2.unrealengine.com/unreal-engine-multi-user-cloud-setup-360515954.pdf
But I am missing anywhere it says about folder permissions, or anything else. Would love a helping hand~
