Here is what I’ve got so far in order to cache the verticies:
local function Liquidize(part: MeshPart)
local mesh = game.AssetService:CreateEditableMeshAsync(part.MeshId)
mesh.Parent = part; mesh.Name = 'EffectMesh'
local MeshVerticies = {}
for _, VertexID in mesh:GetVertices() do
MeshVerticies[VertexID] =
{
Position = mesh:GetPosition(VertexID),
Viscoscity = 1,
NextdoorVerticies = {}
}
end
for _, TriangleID in mesh:GetTriangles() do
local tVerts = {mesh:GetTriangleVertices(TriangleID)}
for _, VertexId in tVerts do
if MeshVerticies[VertexId].NextdoorVerticies[VertexId] then
table.insert(MeshVerticies[VertexId].NextdoorVerticies[VertexId], TriangleID)
else
MeshVerticies[VertexId].NextdoorVerticies[VertexId] = {TriangleID}
end
end
end
end
How can I use the viscoscity values in order to create a natural liquid?

Alright so by using assumptions on how blobs of liquid look, I’ve came to these 3 forces to simulate the behaviour:

I’ve cooked this up, but the mesh is not moving at all 
yes, the EditableMesh is a child of the mesh
I’ve decided to cheat a bit by using Roblox’s engine to sort out gravity and collisions by making each vertex it’s own, invisible part:
local vertexCache = {}
for _, VertexID in ipairs(mesh:GetVertices()) do
local newPart = Instance.new('Part')
newPart.Parent = vPartFolder
newPart.Size = Vector3.new(0.05, 0.05, 0.05)
newPart.Transparency = 1
newPart.Shape = Enum.PartType.Ball
newPart.Name = 'vPart #'..VertexID
local attachment = Instance.new('Attachment')
attachment.Parent = newPart
attachment.Name = 'vPart Attachment'
local forceValue = Instance.new('VectorForce')
forceValue.Parent = newPart
forceValue.Name = 'vPart Force'
forceValue.Attachment0 = attachment
vertexCache[VertexID] =
{
ForcePart = forceValue,
PhysiPart = newPart,
Correction = 1 / newPart:GetMass() ,
GeneralForce = Vector3.zero,
TentionForce = Vector3.zero,
}
end
Using springs I accidently made a soft body
