Preview animation not showing modifiers animation

[pawel_karbarz]

In some reason, when I'm generating a preview animation, it's skip my modifier animations. For example, I've got a model with slice modifier animated from bottom to top but in preview the object just show without this animation (looks like never been slice). Same happen in next phases of the animations, some of the object looks like loosing animations, but some of them are fine (I can't find any relations).

Did someone have same problem?

I haven't had that problem but as a workaround, what if you collapse the stacks as much as you can to keep the animation and then do the preview? After the preview is done, close Max being careful NOT to save it. Then when it opens you have all of your stack back like they were. 

At least that would give you a preview until you figure out why it's not showing some of the modifiers.

Ok, probably problem was related to object itself. So I try to made new scene and do test with box (pass). Later I'm import this problematic object and wasn't work right. So I decide to do it again. I realize the problem was gone after apply XForm mofiier and collapse all of them. Next I'm add slice modifier with animation and works again!

I'm glad I was able to help lead you to a fix. Often, collapsing the stacks and trying again is a good thing to try.
