Hi,
Niagara throws log warnings on server startup like this:
NiagaraSystem /Game/… IsReadyToRunInternal() failed due to missing SystemScript. Spawn[] Update[]
This is probably caused by Niagara not cooked into a server build, which is intended.
With a simple Engine change in :
bool UNiagaraSystem::IsReadyToRunInternal() const
We were able to fix that by adding IsClientOnly() to the condition :
if (FPlatformProperties::RequiresCookedData() && FPlatformProperties::IsClientOnly())
Maybe you can add something like that to the next release?
Regards
Robert
