I have an FX shot I'm trying to work out right now and I have a few questions that relate to it. The shot is this: There is a guy holding a glass of ice tea while sitting in a chair. The ice tea in his glass, lemon and ice cubes all start to float up into the air.
I want the ice tea to float up with a very specific look, almost like it's "dripping" up and a bit cartoonishly viscous. I also want the ice cubes to be affected by the upward dripping liquid. I want each drip to 'fall' at a different rate. This however would possibly require the ice cubes and the drips to be part of the same simulation. I don't think Glu3D includes any physical object simulation tools does it to includes the ice cubes? Should I even create use a fluid sim should I just use a particle flow system with some sort of meshblob generator? I want each drip to look like it's in 0 G, sort of gyrating and pulsing as it tries to maintain a sphere, or now that I think about it, I want the whole thing to look kind of like a lava lamp.
I was thinking one way to do it would be for each drip to be a pflow emmitter and the have it be repulsed by other drips, but attracted to itself. This solution however also wouldn't model the motion of an ice cube 'falling' through each drip and sticking etc.
The only way I've figured out how to do this is to have a gravity force in the middle of the drip and then apply the keep apart node, however this doesn't work because the gravity will bring all the particles in and then they will rocket out and start a cycle of collapse and expansion. Is there a way to treat all the particles like they're little colliding spheres trying to huddle around the same fire?
