Hi,
Can someone please help me confirm is bullet is compatible or not with flip simulations?

I set up a simple packed geo as a static object for a flip simulation.
The geometry collision is properly calculated as convex hulls…

But as soon as I run the sim this weird shape appears:

It is like if the flip sim automatically converts the collision geo into a weird resampled volume.
is this true? Would this mean that the flip solver will automatically convert the packed geo into a volume?

Feel free to look at my set up… I simplified the scene to run a test. (the hip file is attached at the bottom)
