When set, out-of-memory conditions in a local shader compile worker will be treated as regular out-of-memory conditions and propagated to the main process.
This is useful when running in environment with hard memory limits, where it does not matter which process in particular caused us to violate the memory limit.
Usage
r.Shaders.PropagateLocalWorkerOOMs [value]
Set via the console (~) or in DefaultEngine.ini / DefaultGame.ini.
