Potential wrong branch condition about DFAO and Niagara GPU SDF Collision

Particles using Distance Field collision can have their collision controlled by "r.DistanceFieldAO". It appears that the condition in "ShouldPrepareGlobalDistanceField(...)" from DistanceFieldAmbie ...

Niagara module "Beam Emitter Setup" makes attribute Emitter.BeamID flick between -1 and LoopCount every frame

When working with beam and ribbon effects in Niagara, Emitter.BeamID is used to fill Particles.RibbonID so that a looping emitter can spawn multiple discrete beams. Emitter.BeamID is assigned by mod ...
