Texture moving surface
I am trying to achieve an effect whereby a person is ‘revealed’ by liquid ‘filling them up’.
My workflow so far is to model a mesh for the person, matchmove it, and then use Xparticles for a liquid sim inside.
What I’m struggling with is needing to have the surface of the liquid, that is the top bit, a different colour/texture than the sides (the footage, mapped).
I’m currently using triplaner mapping to achieve this but it’s not perfect so I’m wondering if anyone knows a way to texture just the surface or to output a matte from the triplaner?
I hope this makes sense, It’s baking my noodle somewhat.
