phoenix fd and voronoi fracture combine problem

[gagan]

If I understood correctly, try using the original glass to contain the fluid until the exact frame of impact, then switch it out for your Tf glass. You can use a time test to activate the fracture at a specific frame.
Or try a surface test (volume) to activate fracture by animating an object over the glass.

yea thanks for your advice chris, i also thought the same later but i'm solving somehow in continuous way and now i think there is no other to switch. anyway thanks for your help brother.
