Hi there
I’m using Niagara to create a music visualization. So I tried to use Neighbor Grid 3D to get information about nearby particles, but I could not.
Specifically, if the process of reading the AudioSpectrum and filling the NeighborGrid3D is running at the same time, the particle count becomes zero.
The process of filling the NeighborGrid3D was used from ContentExample, so it is unlikely that the process is incorrect.
As for the AudioSpectrum, it only happens when reading from ParticleUpdate, not when passing values read by EmitterUpdate to ParticleUpdate.
I would like to know if there is a good way to use these at the same time. Thanks in advance.
Finally, here’s a simple way to reproduce the issue: open up a sample (any sample) that uses NeighborGrid3D from NiagaraAdvance in ContentExample, add a ScratchModule to ParticleUpdate, and read AudioSpectrum and read
