I'd like to make a scene similar to the FLIP fluid balls, but since it's small scale (about 2-3m diameter) my fluid disappeared, so I went for POP fluid. The fluid collides the internal surface of the hollow sphere, but it gets through the surface. Does anybody have idea, how to solve this? Also, I'm looking for possibilities to use whitewater with pop fluid. If it's not possible, the question is how can I create small scale FLIP fluid simulation? I'm a photographer, and I combine my renderings with the photos I shot, that's why I need the world scale

Cheers

Here is the basic collision setup, with whitewater. You have to remember to invert the field to keep the particle inside a collision object.

Amazing, thank you!

As I see, you used both FLIP and POP Fluids?

I didn't really know how to make white water work with POP FLUIDS so I went ahead and constructed it using the basic FLIP system.

I went through the scene this morning, and again. Now I understand how did you set up the system. Again, amazing, and again, thank you!

Cheers
