I needed to do PBD Niagara for project, basing on this tutorial. But in the end, the same Niagara System in “Prewiew Niagara” and “Niagara in level” are different. Its look like as if the scratch pad responsible for the collision logic does not work at the level,
although scratch pad for collision is enabled.
I think so, because if turn off the scratch pad, then the Niagara preview becomes the same as on the level
I found out what the problem was, I’ll share it, in case anyone needs it. There were many debug moments, but they did not give results. The following worked:
First, I reset the Niagara location to 0.0.0 - then everything started working. But it only worked within 200 unreal units (very little distance). As soon as they went beyond certain boundaries, the collision stopped working again. It was strange, because the specially visualized grid showed a fairly large distance.
Secondly, I had to increase the grid size from 1000 to 10000, and then Niagara began to work at a great distance from 0.
