Lava floor

Hi guys i'm developing a 3d mobile game and i am working with a designer who is asking me a question that i can't really answer. He is designing me a scene with a lava floor that moves and asks the following question: I have a question. To be smart about the materials, I think I would be better to make the map be a shader in engine but I don't know if that would be a good use of resources. in that way I would use a shader as an smart material, with masks and do the geometry of the map. and the textures for the shader, That way the floor can have smaller textures, but I am not sure.

 

Hi,
So what exactly is your question here? Are you looking for ideas how to implement lava animation with a shader or what? Right now that description seems more like a collection of thoughts. Maybe it might help us answer if you clarify what you are trying to achieve.
