Hi Camel,

if you have to tweak only the end of the domino sequence, I'd probably save the scene to another file, let the simulation calculate up to the frame where your fine-tuning starts and then set this as initial state. You can save a lot of time and it will behave exactly like before just without having to recalculate everything.

When everything is fine, the cache is very useful to get a fast playback (or maybe a playblast).
