Suggestion / Idea OBI7 Surface Texture Rendering (Lava) discussion

[josemendez]

Yes, can ObiFluid have this effect? those foam look very very good and big.
The smaller advected particles can be used as bubble though.

Quoting myself here :

Obi does not support this yet, but likely will in the future: all that's needed to be able to do this in a shader is for the fluid mesh to contain velocity information in its vertices, which is very simple to do (at the cost of increased surface chunk memory usage).

Once the fluid mesh has velocity information, this is doable. We'll also throw in a ShaderGraph node to do the actual crossfading of texture coordinates, so you can easily implement this with minimal complexity.
