The team is already aware of this issue as it’s a duplicate of Niagara System Not Triggering in Cinematic and is scheduled to be fixed in 42.10

I went to my island and most Niagara would not work. I noticed that some Mesh particles work tho.

I’ve been shared a workaround that might help with this:
“Change from FX System Toggle Track to a Niagara System Life Cycle Track”

Unfortunately with this workaround you can’t trigger multiple times, you’ll need to add multiple tracks which might be a little annoying - apologies.

Again, a fix is scheduled for 42.10

Hey Rhyan, glad to know this issue is being looked at! Im just wondering when 42.10 will be released for the fix of this issue? A lot of my maps, and other developers rely heavily on this feature :slight_smile: thank you!

My whole island relies on this featured. 42.10 is scheduled on September 3rd which is 10 days from now..
