Are you gonna do a deepdive on how you built this? I’m craving the knowledge🤪

Tosca aka nanotopia

Played with it yesterday-very cool! Looking forward to your upcoming deeper dive tutorial.

Thank you SARV !!!

Hi, excellent and thanks for sharing. Unfortunately not working for Mac and I am having a look to why...

Same here for only 5 days I couldnt upgrade my license... Have you manage to resolve this problem?

How would you go about creating a renderable fluid geometry for this? I would like to render with PBR or substance to make a realistic interactive water sim installation.

Great work! However I am getting strong and weird jerks of the particles, even when the strenght of the noise is small and the force multiplier is well bellow 1. If I add trails, I get a lot of weird very long and straight lines. What can it be? I am using 2025.31760 on a Mac, with the code changed as per the comment

I've got the same problem - it seems lowering the force multiplier helps, but I haven't been able to figure out how to remove it completly

Felipe Faundez

Stunning work! Sadly, I’m still struggling to make it work on a Mac. I’m not sure where to add the code (I’m a newbie). Could any Mac user who got this working please share the file? Cheers.

Is there anyway to have the edge behavior be to teleport to the other edge of the bounding box instead of staying physically contained? So that I might create a constant flow in a particular direction
