How to keep liquids in the air? - asimofu_ok - 14-08-2024
The new Obi 7 looks like it has terrific potential.
By the way, I could not figure out how to keep the liquid in the air as shown in the Asset Store video.

How is it done?
Also, do you have any sample scenes that do this?

Hi,
Just set the solver's gravity to zero
To elaborte further: setting the solver's gravity will affect all actors in it. If you only want to affect a specific fluid emitter, you can use its blueprint's buoyancy parameter to control how strongly gravity will affect that specific fluid. Setting it to zero will disable gravity for that specific fluid.
As for the rotating effect in the video, it's a spherical force zone with negative radial acceleration so that particles accelerate towards its center.
kind regards

I wondered if there was a means by which the fluid could be held in a particular shape.
Thank you.

Yes, you can also do that. Use a distance field force zone with negative radial magnitude, it will attract particles and keep them in a specific shape like this:
