I'm simulating a flip fluid inside a tea cup, on a character's hand (using Volume Collision and Alembic (deform collision))
Everything looks fine until the hand starts to move… The fluid doesn't stay inside the cup like it should be - Iike any of us walking while carrying a tea cup.
It's dropping away over the border like was in a fast movement.
I'm not sure how to solve this because the hand moves very gently… It's not a fast movement. Scale is also correct… And I'm using trail on calculate the velocities.
Sorry but I can't share the file.
