how to convert a shape key animation to a fluid? So I just finished this tutorial by Tutor4u using shape keys to convert a rolling ball into a wine glass. after that animation I would like to convert the wine glass into a fluid. The problem is I cant seem to get the wine glass to interact with the fluid physics. I can easily get it to work with regular objects in separate files no problem. 

here is the tutorial https://www.youtube.com/watch?v=qx5L8K99j10&amp;t=1476s

This is my third day with blender, so I am probably missing something very simple.
I suspect that I am not setting some time parameter to account for the animation in the beginning, or that the fluid portion doesn't recognize the wine glass because it switched materials.

Id appreciate any feedback. this is driving me nuts!!
Ok now it's clearer. If I got what you mean, I tried a (much simplified and rough) example.

I started from a simple sphere, set basis shape key, 



added another, shaped it like a glass extruding vertices, 



had the morphing effect. 



Then set the morphed glass object as fluid, 



added a surrounding big cube, set it to fluid domain, 



and baked the domain.



When it finished, I hid the original glass shape, keeping only the domain visible. Now it seems to splash as you expect... does it?



Is this not working for you? Did you forget to bake? Of course I used rough fluid settings, you'll need at least much finer domain resolution.
