I was exporting the fluid as an .abc file and then reimporting it, hoping I could have it collide with my cloth. I know that the cloth would not affect the fluid this way but I thought the fluid could at least affect the cloth.
I tried baking the fluid animation to keyframes but I am failing at that already apparently. The other day I could export it as an .mdd file and I think that I had it keyframed when I reimported it, but I get an error message both on export and import of mdd.
Maybe .abc/alembic cache is the better way to export that anyways, but, as I said, how can I have it affect my stupid cloth simulation?
