Simple Question about fluids
show user profile  herfst1
If you have a glass/cup/bottle that's meant to have liquid in it how would you go about achieving that?

I'm sure there's some fluid plug-in but I'm more interested in the fake way as none of these liquids will be close to the camera (though if you want to describe the realistic way using fluid dynamics, it can't hurt).

P.S. Don't complain about lack of capitals in my post, it's Saturday in my timezone.

The way I assume would work is to make a closed box inside the glass/cup/bottle that matches the shape of that container and apply a fluid-like material. If so, how do you make a duplicate of the inner shell without shift-moving it (as I don't want to mess around trying to get it back into the exact spot, and I know when you shift-drag a face to a new object it keeps the original pivot point)?

Or would you just need to create the top surface of the liquid and use material ID's to change the inner shell of the container to some liquid material? But would that have an effect on the glass refraction (or wouldn't it matter)?

Particles wrapped in metaballs is the oldskool easy/quick way..

[edit] Well if it`s static yeh just a material :)

Never heard about that, will look up metaballs. Thanks Dave.

[edit] Just saw your edit. Maybe I'll metaball some particles in the future. Thanks for the tip.

Hmm...would only consider particle based solution if there was a need.

If it is still,...and not moving....then Herfst is proper way. Use inside shape, create seperate fluid object....proper use of refraction on both exterior glass and fluid object is important. Exterior glass also needs proper thickness,....not just paper thin...etc.


edit: again,...metaballs ONLY if its moving....

Excellent. Will start filling my liquor bottles now. Thanks for the confirmation, Jim.
