Fluid simulation question

Why does the domain seem to disappear after I press bake?

When you bake the domain becomes the fluid. If the baking results in no fluid, the domain will disappear… …kind of. You can still select it in the outliner and rescue it by setting “disp-qual” to “geometry.”

If you find that there is so little liquid being produced that you it barely shows up in the viewer, then before you press bake, set the display quality to “Final”. That means you’ll see the final product in the 3d viewer.
