Hi,

I've exported a point cache from houdini (hbjson format) (frames 0-100) where I'm emitting 100 points on frames 1, 11, 21, and 31.

bringing that into unreal/niagara via HoudiniNiagaraBasic emitter. The points on frame 1 show up correctly, but the points on 11,21,and 31 all show up 1 frame late.

looking to get exact parity between houdini and unreal. thanks for any insight.

looks like shutting off the (default) interpolated spawning helped.
