Decided to take a short break from my Hair simulation stuff. ambershee suggested in IRC working on metaballs, so decided to take the work done by NVidia and implement it into UE4. First obstacle was that the Vertex Factories aren’t set up to use a Geometry Shader, so I modified this and allowed Vertex Factories to opt in for a Geometry Shader. Once I figure out the best design, I will submit a PR so that others can use Geometry Shaders with Vertex Factories in the future.
50 or so Metaballs with standard Reflection (Prior to adding Tangents and UVs).
Metaballs with UVs no Tangents.
Metaballs using a custom UVW blend to blend depending on Normal direction.
Metaballs in motion.
Still deciding on where this will go. I am thinking of replicating Crysis cave building system using metaballs and then there is also Portals goo.
