Niagara sand particles collision issue for logo reveal

Hello everyone,
I’m developing a logo reveal animation: the idea is to have the logo mesh semi-buried in the sand (a landscape) and gradually reveal it with forces like attraction force, wind etc.

So far I’ve made a niagara emitter that spawns tiny meshes across a texture mask that sort of matches the actual logoshape, the issues are many:

  • spawn rate/ spawn image resolution ratio: it’s hard to render so many microscopic meshes that cover the logo in a convincing way

  • collision: so far the most important issue is that the particles just dont collide with the logo mesh, only with the landscape.



  • attraction actor: I’ve made also a blueprint actor that changes in viewport and during gameplay the point of attraction force and radius so i can’t animate it in the sequence, but sometimes it just decides to not work properly during sequence, and the strangest part is that the niagara freaks out and registers the change in forces all the time (like if it was prebaked) regardless of the actual parameter i’ve set


Hopefully I’ve explained it well enough, thanks to whoever will take the time to read all of this and help me out, there’s probably a lot of improvements i have to make so any suggestions/solutions are welcome :
