Love your vids man, thank you for sharing!

[@Kratosagz]

Amazing tutorials man, keep going!

[@YuuJer]

more niagara videos pls!

[@VisualTechArt]

I'd love to! They'll come :D

[@DerPolee]

do you know how to update the values in Niagara Parameter Collection? in runtime?

[@VisualTechArt]

I was playing with them a while back ago and to be honest they weren't working at all, I should check again

[@DerPolee]

@@VisualTechArt I got them to work but I don’t know how. They just suddenly started to work. There is also a node called „ get Niagara parameter collection“, with the return from it I could set the prameters similar to regular mpc. After some test I have removed all the stuff because I wanted to just use the regular Niagara user exposed parameters but the npc is still updating somehow.
