I tried to make an animation with fluids for the first time, and I modeled the jug without tutorial after one I have myself. I used a cylinder as the geometry for the fluid, but the moment I started the simulation it started spilling out around the horizontal ring of faces at the bottom of the handle.
When I checked the normals I noticed that they weren't pointing outside. The walls of the jug have thickness, and the normals on the inside all point correctly. To make sure, I flipped the normals of these faces, and the liquid actually stayed inside, however, now the shading for that area is messed up.
Does anyone have a tip how to fix this?
Edit: I managed to get all the normals flipped correctly, with it still looking correct, however, the fluid still spills at the same location.
