Underwater bubbles without liquid

[cb LLC]

Hi I know you can simulate and output foam bubbles without outputting liquid channel. Unfortunately our liquid does not settle well messing up bubble movement. Anyway to have bubbles animated without any liquid simulation but still have underwater movement feel and look. ? We need it when the submarine is moving around. Thanks

Hey,

Without liquid, I think the only other possibility is to use forces and turbulence and adjust them so that you get the feel you want. Hopefully using the force preview would help make this easy

Cheers!

You could mesh a temperature-sim, but maybe this would be too blobby.

Surely no sim is needed, pflow and a mesher.. done

Thank you !

Hi Svetlin,
would be nice to have an option in the future for liquid without velocity. is it possible? That way liquid will have no movement almost like ice but you can still simulate particles like bubbles

umm pflow and frost would surely give a better result and much faster? even a simple phoenix smoke sim exported as PRT files and then meshed can work nicely

Try adding a Plain Force with very weak strength like 1 and maximum drag 1.0. Set it to affect liquid. That maximum drag would dump all the velocities and the liquid should "freeze".

Oh yes, something similar can be done even now. To make the liquid particles completely lifeless:
- Turn off or lower the gravity.
- Make sure viscosity and surface tension are both 0.
- Turn off the Conservation - this can be done in the Fire/Smoke simulator, but for FLIP liquids it doesn't always make sense, unless you want to do evil stuff like in this case, so it's accessible only by script. Select the simulator and type $.reflprec=0.

In this state the FLIP particles should behave exactly like pflow particles and if you drop in a 3ds Max force, it should affect both Phoenix and pflow particles the same way.

If you want to mix these dumb Liquid particles with Foam, it could be quite interesting..
