I have just run out of time. Was trying to use Mantaflow to create a realistic water draining away but it just kept failing! So had to compromise with just altering a cube, subdividing, rotating the vertices. Not exactly the look I was wanting but it will have todo.
Yeah I feel you, I was having issues with it too and decided to go another route. I should spend some time to learn the mantaflow process for the future.
I like how you adapted though and still got your scene to work!
Nice man! I went with the node editor myself, tying to get more familiar with it! Some water condensation on the glass would take it to the next level! + a little bit of noise texture connected on a bump map in the lemon material would give it the texture that it has as they are not that smooth, this in turn would add to reflections etc, but I get the pressure of the deadline, believe you me!
Issue I had was, when there was just a plane the fluid would land on it and act like fluid just like any of the tutorials when using just the domain. Then as soon as you put a hole in the mesh, the mantaflow fluid would going straight through everything and land on the bottom of the domain.
Had the same thing a couple of months ago when attempting to make a Volcano erupt.
It seems as though it is quite buggy for this purpose.
