I want to make a scene featuring a killer mermaid. I've run into two big issues: the flow of the hair and the effect of her prey's blood in the water, though I've put the blood thing into a separate question.
I want the mermaids hair to float around like it's being affected by the current, as well as move accordingly when she moves in an animation. The best examples for the hair effect that I can think of are Salazar from Pirates of the Caribbean: Dead Men Tell No Tales or the mermaid from Playdead's Inside:
How can I go about this?
