While following this tutorial: Unreal Engine Niagara Tutorial - YouTube I get to the stage where i’m adding the particle spawn module that sets a vector variable with a random tri coordinate of a static mesh sample. As soon as I add the module, my emitter is unable to play. If i remove the module from my emitter it still can’t play, and any Niagara systems I have with the emitter in them also won’t play, removing the emitter from the system doesn’t fix it. Why?
Seems that force deleting the module works, I found this in the output log:
LogNiagara: StaticMesh data interface has no valid mesh. Failed InitPerInstanceData - NiagaraDataInterfaceStaticMesh /Engine/Transient.NiagaraComponent_1:NiagaraDataInterfaceStaticMesh_0
LogNiagara: Error: Error initializing data interface “/Engine/Transient.NiagaraComponent_1:NiagaraDataInterfaceStaticMesh_0” for system. 1887259520 | NiagaraSystem_0
