Sorry, I checked on the Liquids, Gloria,

The Speed of the particle is pretty high. Perhaps start with 75.

Place a Collider Modifier (from the particle menu) under the particle Folder.

• In the Attribute Manager> Mode> Scene> Simulation> Particles> Substeps is set to 1.0, explore, e.g., 60, then dial down.

The Substeps check if there is a particle that might collide. If that number is higher, it checks more often.

I hope that helps. I don't have a fast enough computer to fine-tune this.

I call it a day now. (…past midnight)

My best wishes

Thank you very much, Gloria! Very kind of you!

Thank you for your patience with my moderator's wishes about structure. Very much appreciated.

Whenever you have any questions, please feel free to just ask. I'm happy to look into it.

My best wishes for your project!

Hi Yu Ken Tsai,

Thanks for the scene file, and the timestamp.

There is no real fluid behavior possible. Fluid would require a lot of interaction among all particles.

The trick for the scene in question would be to cheat.

Please have a look here.

I have changed the iteration and the Scene Scale, added Dilate and Erode to it, and animated a cube as a fill cheat.

This is just a sketch; you might need to fine-tune it.

All the best

Hi Gloria,

There are two ways to do that.

Either use the little "traffic Light" in the object manager (the top light is for editor view, and the lower one is for rendering. If you use both, the non-render/show option will win, none allows to be overwritten to render.

The traffic lights can be click or "painted" if you like to click and drag. Option Click changes both. BTW, gray means, it uses the parent setting.

OR use Layers (Layer Manager); the R column allows for managing those.

Please have a look here:
