EditableMesh:GetAdjacentTriangles only returns {0, 0, 0}

Calling GetAdjacentTriangles with any stable triangle ID only seems to return a table of 0’s. I have included a repro file of this issue with an mesh and the following code:

local AssetService = game:GetService("AssetService")

local editableMesh = AssetService:CreateEditableMeshFromPartAsync(script.Parent)
local triangleIDs = editableMesh:GetTriangles()

for _, triangleID in pairs(triangleIDs) do
	print(editableMesh:GetAdjacentTriangles(triangleID))
end

Thanks for the bug report, we can reproduce this locally, and will look into it.

Unsure if this is related, but I can’t seem to open another bug report so I will attach it here as well.

I have found some cases where EditableMesh would return an empty list for GetTriangles() but returns vertices fine with GetVertices(). Attached below is a repro file.

I’m having this issue too, though :GetAdjacentVertices() has been working fine for me, hope they get this fixed soon

local AssetService = game:GetService("AssetService")

local mesh = AssetService:CreateEditableMeshAsync("rbxassetid://452936006")
mesh.Parent = workspace.MeshPart

print("Adjacent Triangles:")
for i, v in pairs(mesh:GetTriangles()) do
	print(table.unpack(mesh:GetAdjacentTriangles(v)))
end

print("Adjacent Vertices:")
for i, v in pairs(mesh:GetVertices()) do
	print(table.unpack(mesh:GetAdjacentVertices(v)))
end
