Hi guys, I need help, I am trying to find a way to visualise my velocity by curlnoise in popnet, before any particle is emitted, so that I could tweak it to the direction/pattern that I want.

The result should just be like using volumetrail node that require a volume velocity.

Please advise, thanks!
