How to bake PolyFX animation??

perhaps someone will know something else but since the points are not actually moving if the cube is all one piece I can only do it by following these steps

Select the cube's faces - Disconnect (uncheck Preserve Groups)
Add a PointCache tag - Store State and Calculate at this point you can turn off the PolyFX and the Effector

if you want keyframes
open the Timeline and drag the cube into it if it's not showing
select Functions/Bake Object... and make sure PLA is checked off in the settings before you hit OK

yeah it needs to be on, that's what I thought I was saying but I see the confusion :-)
