Scale
The Scale of a mesh determines the size of the mesh relative to its original dimensions.
How to use mesh scale
The scale property works slightly differently depending on the type of mesh being used. Note the size of the BasePart
remains unchanged, meaning the physics collision box of the part will remain the same.
SpecialMesh
objects withSpecialMesh/FileType
set to ‘FileMesh’ scale relative to the original dimensions of the mesh when it was uploaded to RobloxBlockMesh
objects orSpecialMesh
objects withSpecialMesh/FileType
set to ‘Brick’, ‘Wedge’ or ‘Sphere’ scale uniformly relative to theBasePart/Size
of their parentCylinderMesh
objects orSpecialMesh
objects withSpecialMesh/FileType
set to ‘Cylinder’ scale relative to theBasePart/Size
of their parent. Uniformly for the cylinders height axis and maintaining a 1:1 ratio for the length and width of the cylinder, using the lowest value.SpecialMesh
objects withSpecialMesh/FileType
set to ‘Head’ currently scale in a non standard manner. Developers should not rely on this as their are plans to change this behaviorSpecialMesh
objects withSpecialMesh/FileType
set to ‘Torso’ scale in a non standard manner. Developers should not rely on this as their are plans to deprecate this mesh type.
Mesh scale demonstration
The above behavior can be seen in the following demonstration images.
Linear scaling relative to part size for ‘Brick’, ‘Wedge’ and ‘Sphere’ meshes.
Linear scaling relative to original uploaded mesh for ‘FileMesh’ meshes
Non-uniform constrained scaling for ‘Cylinder’ meshes
Other uses for mesh scale
There are a number of interesting uses for the mesh offset property.
DataModelMesh/Offset
and Scale can be animated usingTweenService
relatively inexpensively as the engine does not need to make any physics/collision calculations as theBasePart
is not changed.- Changing the relationship between the mesh and its collision extents (determined by the
BasePart
)
Code Samples
Mesh Offset and Scale
In this code sample a BasePart
is instanced with a SpecialMesh
. The DataModelMesh/Scale
and DataModelMesh/Offset
properties of the SpecialMesh
are then animated using TweenService
.
local TweenService = game:GetService("TweenService")
-- instance a part and a mesh
local part = Instance.new("Part")
part.Size = Vector3.new(4, 8, 4)
part.Position = Vector3.new(0, 4, 0)
part.Anchored = true
part.CanCollide = false
local mesh = Instance.new("SpecialMesh", part)
mesh.MeshType = Enum.MeshType.FileMesh
mesh.MeshId = "rbxassetid://1086413449"
mesh.TextureId = "rbxassetid://1461576423"
mesh.Offset = Vector3.new(0, 0, 0)
mesh.Scale = Vector3.new(4, 4, 4)
-- selection box to show part extents
local box = Instance.new("SelectionBox", part)
box.Adornee = part
-- parent part to workspace
part.Parent = workspace
-- animate offset and scale with a tween
local tween = TweenService:Create(
mesh,
TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, -1, true, 0),
{Scale = Vector3.new(1, 1, 1), Offset = Vector3.new(0, 3, 0)}
)
tween:Play()
