Hello,
We are experiencing an issue on Roblox Studio where when you resize any Part or MeshPart it lags really bad for the person doing it, and everyone else in the team create session. This happens on any part, brand new or old. It does not happen on things inside a Model. Most team create users are on the newest studio version.
Expected behavior
The part should resize without lag.
Hey @chickenputty ,
Did this start when you added a certain part/mesh? How recent is this issue?
It happened after we added a MeshPart with Bones (for an animation with mesh deformation). We delete it, and the problem is “fixed”. However, we need to keep this in the game for our new update, so we cannot keep it deleted.
Specifically, it happens when ModuleScript has the children of a MeshPart with the children of Bone (with bones inside the bones). If the MeshPart is in a model within the ModuleScript, it is fine.
We can work around this for now by keeping it in ServerStorage, no need to rush a fix before the holidays.
Could you check if Studio lags on local Studio as well once you add this part? with Team Create off
Yes, it does. I downloaded an offline copy and was able to reproduce.
Seems to happen when the MeshPart is parented to Workspace too. Not only ModuleScript. But, I put this MeshPart into a blank workspace and cannot reproduce there. It’s very strange.
I accidentally made a duplicate post. It’s now completely broken even after deleting all Bones from the game. Not even in ServerStorage or ReplicatedStorage or anything. Completely deleted and the issue is persisting.
INTERESTING NOTE:
I deleted the MeshPart that the Bone was originally inside of, and it resolves everything. Like, there is no Bone inside of the MeshPart, I’m still lagging like crazy, then I delete the MeshPart from workspace and it is smooth again.
putting it inside of a Model 100% fixes things.
This is a known issue that we are planning to fix, thanks for your patience. In the meantime here is a script that will find all skinned meshparts in the workspace and put them under models if they aren’t already, which should resolve the issue:
local function addSkinMeshModels(parent)
children = parent:GetChildren()
for _, child in children do
if child:isA("MeshPart") then
if child.HasSkinnedMesh then
print(child.Name)
model = Instance.new("Model")
model.Name = child.Name
model.Parent = parent
child.Parent = model
continue
end
end
if child:isA("Model") then
continue
end
addSkinMeshModels(child)
end
end
addSkinMeshModels(game:GetService("Workspace"))
