Hey ! Here are some test I made during pre-production time.
The first one was made in order to mix it with CG water and assets, I've paint some 2D asset in Photoshop and animate it with After Effects.
The Other one is a test for rendering, made in maya with mental ray.
I used the free character RIG Jin for this test : https://www.youtube.com/watch?v=ofHmbxiVkuE
