I have an assignment involving waterfalls, but I've chosen to have multiple levels of pooling spouts. I have 4 levels, including the top and bottom. I tried using the merge node to put them all into one input for the flip solver, but it doesnt register. Ive also tried putting them all in on one input and the solver only allows one. If I could get some input, that would be great.
Thanks

Have a look at the attached file.

thank you
