- bUsePlatformFileStub = true replaces the default platform file. The default PF is saved and can be reused at any time.
The side effect is lots of warnings for missing files and object loading errors which is acceptable for low level tests.
- bMockEngineDefaults = true sets some mandatory engine defaults (materials, fonts etc) that can only be loaded from cooked assets.
