I want an object to emerge from the water. So I've created a domain and a water object in order to create my water.

When I begin the simulation it needs several frames for the water to settle down into the domain (edit: I could have simply made the Flow object a bit bigger than the Domain but anyway...), so I thought I should begin the calculation at frame -50 for example (Cache > Frame Start), so that the water has already settled down when the animation begins, but it doesn't change anything (!?!), the animation is exactly the same and it still takes several frames for the water to settle down.

What am I missing? Thanks. File here.

The Offset value you can enter in the Cache settings is just usable if you're loading a saved simulation cache and doesn't work for baking. Baking can only be calculated between positive Start and End frames. Before I simply retype everything that's in the manual, here is a screenshot:

  • $\begingroup$ a bit tedious for the collision object animation though as you need to offset it then bring it back $\endgroup$
