So, for the up coming "holiday" I was working on a Patty's themed render, and was considering animating it, but the problem was liquid.
I've gone over a bunch of the different hacks for faking liquid, but I needed something that worked within an object, like a glass, or at least looked like it did.
Found a quick tut on what looked like liquid filling up a cylindrical container using the Random Effector. This only really gave the appearance of wobbling/waving but wouldn't react with gravity/the glass moving.
So, I ended up with this, animating a shear deformer, and rotation, as well as a minor scal adjustment to keep it touching the glass to keep the refraction looking proper.
Not perfect, but it was fun to search for a solution.
I don't think I'll be doing the actual animation in the end, at least not for this Patty's Day. It would work for just taking a drink, which was all I was really planning, though I the head goes above the edge of the glass when it tips, but still is shaped like it's inside the glass. Not sure how I would go about fixing that, though, if I wanted to have it pour out, then the emitter and metaball liquid fake would work. Though I'd be curious to see how I could work that with the head and the body.
Any who, just thought I'd share what I ended up with:
