I am trying to render a simple water simulation, where 2 inflows run down ramps, and then collide and fall down. Everything is fine in the preview, but when I go to render, it works fine for a few frames, but then turns solid. I am trying to render in Cycles. Attached is the .blend file. Thank you for helping!
For anyone in the future, select your domain object, hit Tab, and subdivide it with W Then re-bake your fluid animation via Physics > Settings > Liquid > Cache. Select all under the type and bake. This allows the bake to have more vertices to determine the domain and flow.
