Hi SwanOwl, Welcome to the Forums,

I think Niagara particles will be a great fit for simulating the spores.

Some of the Niagara features are demonstrated in the [Content Examples](https://www.unrealengine.com/marketplace/en-US/product/content-examples) project.

Also I noticed this ‘[Particle Wind Control](https://www.unrealengine.com/marketplace/en-US/product/particles-and-wind-control-system)’ asset in the permanently free collection. It uses the previous particle system ‘Cascade’ but could be worth a look.

So I’d start with the Niagara Particles ↔ Wind interaction. (You’ll want to create a way to control the wind via keypresses so you don’t pass out when trying to test it. 😉 )

Getting fan input in UE is an interesting problem. Maybe the solution involves an [arduino](https://forums.unrealengine.com/t/free-windows-only-ue4duino-2-arduino-com-port-communication/95217). To be honest the idea of festival-goers blowing strongly at a specific object is off-putting. (Going to chalk that thought up to post-covid trauma 😷) An alternative idea would be to have them rotate something, and the rotation the object translates into rotating the wind direction, plus maybe a slider to control the wind speed.

Let us know how it goes!
