Domain becomes fluid when baking fluid scene.

Support Compositing and Post Processing

I’m new to this forum and a bit of a NooB to Blender.

I’m using version 2.44 on a Powerbook.

I’ve set up a simple scene that drops a sphere of water (Fluid) onto an object (Obstacle) within an enclosing cube (Domain).

As I understand it the Domain is a box that encloses the scene and should do little else ?
However when I come to bake the scene, the Domain becomes the fluid and wraps itself around the sphere and it ends up looking like it’s made up of square particles and doesn’t seem to behave as I would expect.

The tutorial on fluids reads:
“The domain is the region where the fluid simulation is performed - all fluid objects outside of it are ignored, and the fluid can not flow out of the domain.”

I have also seen posts from a moderator that say the Domain becomes the fluid when you click ‘bake’

“When you press Bake the Domain mesh should turn into the Fluid and start doing its thing. If it doesn’t then you should tinker with Resolution and Velocity values till it does.”

Can someone tell me if the domain should become the fluid or guess at what I’m doing wrong.

Thanks :spin:

Yes, the domain becomes the fluid.

Changing the resolution will up the amount of vertices in your final object and it will therefore be smoother in appearance.

also, the fluid that you see in your 3d viewport is not the fluid that you render (necessarily).

The preview fluid has a different resolution than the render fluid (to speed up the viewport). you can set this preview resolution next to the actual resolution.

Also, put set smooth and perhaps subsurf on the fluid after it has baked to make it look better.

Thanks for your help, I see the different resolution items now.

I was starting to think there was a bug in my version as it seemed a bit strange that the Fluid object stayed where it was and the Domain became the fluid. I guess there’s a good reason it’s done that way, but on initial viewing it did seem a bit counter intuitive.
