Helloo Epic team,
Hope you’re all doing great! 
We’ve come across an issue in UE 5.8 where Niagara Fluids doesn’t appear to be working. To make sure the issue wasn’t related to our custom build, we also tested it in the vanilla engine and observed the same behavior.
I’ve attached a few screenshots to illustrate the problem.
Could you please let us know if you’re aware of what might be causing this issue or if there are any known workarounds that could help us get Niagara Fluids working? We’d really appreciate any guidance. 
Thanks in advance for your help!
Wishing you all a lovely day!

Hi Sara,
Could you elaborate a bit more on what isn’t working with Niagara Fluids on your end?
Apart from the log mentioning missing attributes, everything appears to be working correctly on my side. Is the system not emitting anything at all? Or does the issue only occur when you try to modify a parameter or attribute?
Any additional details about the behavior you’re seeing would help us narrow down the issue.
Thanks!

Hii Stéphane!!
The mystery is solved! Our team checked that, by default, Unreal Engine 5.8 sets the Engine Scalability Settings to Medium when creating a game template or basic project setup. With these settings, Niagara Fluids do not appear.
Thank you so much for your continuous support!
Wishing you all a great day!

Hi Sara,
Thanks for your reply and for confirming this is actually not an issue.
Engine Scalability can change depending on the user settings or project configuration (through custom Editor.ini file for instance). It should be at 3 (Epic) scalibity by default though.
Let me know if you have any other info/questions around that, and I’ll close this ticket accordingly.
Thanks!

Hii Stéphane!!
Thank you so much for looking into this issue!
The team mentioned nothing is emitting, but I’ll try to fetch more details from them and get back to you.
Have a great day!
