After hearing about how much the Bullet Physics Solver is the second coming of solvers over the past couple of years, I wanted to finally give it a go. The PhysX solver is fast too, but the implementation of it is just awful in practice...especially for heavy scenes that I've come across.
I can see why people love Bullet; it's fast. This scene took less than 5 minutes to sim. I'm pretty sure I could've done this 4-fold and still have gone farther. The only downside I came across is that it's very wonky. It starts off as an exploding nightmare and then you have to really dial in your settings to avoid your geo just flying everywhere.
However, once you dial it in, it is pretty smooth. I think for things where there is tons of chaos and you aren't looking at individual pieces, Bullet is a great choice. But, for hero shots, the SC solver is still the best in my opinion. :)

Hmm…it looks like things are taking a while to load. Try again?
