Niagara data interfaces not appearing

So im trying to use Grid2D’s to calculate data in niagara but in my emitter, there should be a section for data interfaces in the emitter properties panel but it doesnt show up. Ive tried enabling niagara plugins and changing engine versions but i cant get them to show anywhere. Any ideas??

Have you enabled the NiagaraFluid plugin?

I’m running into this same issue, and am banging my head against the wall. I’m starting to feel like this is bug territory…
